BACKGROUND: Interest in minimally invasive procedures has recently increased because it results in less surgical trauma, decreased patient discomfort, short hospital stay, reduced costs, and better cosmetic appearance. Based on these facts, we have been using the transxiphoid process approach without sternotomy for the correction of atrial septal defects. METHODS: From July 1996 to January 1997, the xiphoid process window approach was performed in 10 patients with ostium secundum atrial septal defect. Ages ranged from 6 months to 14 years (mean, 5.3 years). In all patients, extracorporeal circulation was carried out by means of cannulation of the femoral artery and both caval veins and of aortic cross-clamping. Videothoracoscopy was used to improve visualization of the aorta. RESULTS: There were no intraoperative or postoperative complications, and in all but 1 patient, extubation was possible while in the operating room. CONCLUSIONS: The xiphoid process window, with no median sternotomy, permitted closure of the atrial septal defects with good results and could be used as a less invasive technique for their correction. 相似文献

OBJECTIVE: Median sternotomy was performed by 2 different techniques in order to determine whether there was a difference in the incidence of inadvertent pleural entry. EXPERIMENTAL DESIGN: Patients were prospectively evaluated and reviewed at a mean follow-up interval of 8.2 months. PATIENTS AND METHODS: Ninety five consecutive patients underwent primary sternotomy at a single tertiary referral center. MEASURES: Planned outcome measures included, incidence of pleural entry, length of hospitalization, and chest tube site related postoperative morbidity. RESULTS: Group 1 (n=49) had sternotomy undertaken from the sternal notch proceeding downwards. Group 2 (n=46) underwent sternotomy performed from the xiphoid upwards. Mediastinal evaluation revealed a significant reduction in the incidence of pleural violation for group 1 (3) versus group 2 (11) (p=0.014). This difference was not found to be surgeon specific. CONCLUSIONS: Sternotomy undertaken from the sternal notch proceeding downwards is shown to be associated with a reduced incidence of inadvertent pleural entry. Potential advantages for this approach also include reduced respiratory morbidity, less chest tube site complications and a trend to reduced length of hospitalization. 相似文献

BACKGROUND: In most cases of transposition of the great arteries with ventricular septal defect and left ventricular outflow tract obstruction, a Lecompte procedure (réparation à l'étage ventriculaire) is possible without interposition of a conduit between the right ventricle and pulmonary artery. However, the anterior location of the pulmonary arteries after the Lecompte maneuver may be a potential cause for right ventricular outflow obstruction, which continues to be reported in 5% to 25% of cases. We have used a tubular segment of aortic autograft to connect the pulmonary artery, left in the orthotopic posterior position (without the Lecompte maneuver), to the right ventricle in 10 consecutive patients with transposition, ventricular septal defect, and left ventricular outflow tract obstruction. METHODS: Ten consecutive patients aged 2 months to 11 years (mean 32 months) have undergone a modified Lecompte operation. Eight had severe pulmonary stenosis, two had pulmonary atresia, and four had a restrictive ventricular septal defect at the time of the operation. Two had multiple ventricular septal defects. Seven had undergone one (n = 5) or two (n = 2) previous modified Blalock-Taussig shunts. All patients underwent a total correction with left ventricular-aortic intraventricular connection (four needed a ventricular septal defect enlargement), connection between the right ventricle and pulmonary arteries with a tubular segment of autograft aorta, without the Lecompte maneuver (anterior location of the bifurcation of the pulmonary arteries) on the right (n = 6) or the left (n = 4) of the aorta. No valvular device was used for the right ventricular outflow repair. RESULTS: No early or late deaths occurred. One patient with multiple ventricular septal defects needed an early (2 weeks) reoperation for a residual muscular ventricular septal defect. All patients are currently in New York Heart. Association class I, without medications, in sinus rhythm, at a mean follow-up of 30 months. Late results up to 3.6 years show no calcification on the chest roentgenogram, and at the most recent echocardiogram, right ventricular pressures were low (25 to 40 mm Hg, mean 33 mm Hg) and no significant gradient (over 10 mm Hg) was found between the right ventricle and pulmonary arteries. Left and right ventricular function was satisfactory. CONCLUSION: This modification of the Lecompte operation using a segment of autograft allows an excellent early and late result, with no danger of compression of anteriorly placed pulmonary arteries, no significant right ventricular outflow obstruction, and normal appearance of the tubular autograft. In view of laboratory and clinical evidence, normal growth of the autograft can be anticipated. It allows an elective correction of transposition, ventricular septal defect, and left ventricular outflow tract obstruction without a previous Blalock-Taussig shunt (three patients) and correction at a young age (three patients younger than 1 year). 相似文献

Isolated secundum atrial septal defect is one of the most common congenital heart defects. Surgical closure is the treatment of choice but is associated with a chest scar, some morbidity and a relatively long recovery and the use of cardiopulmonary bypass. Transcatheter closure of secundum atrial septal defect is therefore an attractive approach. 3 children, aged 5-10 years, underwent successful transcatheter closure of moderate to large central atrial septal defects with the Cardioseal device. The procedures were performed under x-ray and transesophageal echocardiographic guidance. Our initial experience, and that of others, indicates that transcatheter occlusion of secundum atrial septal defects is safe and effective and can be an appropriate alternative in approximately 60% of patients. 相似文献

An unusual case of chylothorax is described in a 4-year-old child after repair of a ventricular septal defect and ligation of a patent ductus arteriosus through a median sternotomy. Left chylothorax developed after a latent period of six days and was treated initially with continuous drainage and parenteral supplementation of proteins and lipids. Operative intervention with oversewing of the site of the leak in the anterior mediastinum proved necessary after three weeks. The anatomical variations of the thoracic duct are outlined to explain the occurrence of chylothorax after diverse intrathoracic operations. The physiological effects of a thoracic duct fistula and various aspects of management are reviewed. 相似文献

From July 1990 to April 1993, 36 lung transplantations in 33 patients were performed in our pediatric transplant program (0.25 to 23 years, mean age 10.3 years). Eight children had been continuously supported with a ventilator for 3 days to 4.5 years before transplantation and three were supported by extracorporeal membrane oxygenation. Indications for lung transplantation in this pediatric population included the following: cystic fibrosis (n = 13), pulmonary hypertension, and associated congenital heart disease (n = 10), pulmonary atresia, ventricular septal defect and nonconfluent pulmonary arteries (n = 3), pulmonary fibrosis (n = 6), and acute respiratory distress syndrome (n = 1). Three children underwent retransplantation for acute graft failure (n = 2) or chronic rejection (n = 1). Pulmonary fibrosis was related to complications of treatment of acute of myelogenous leukemia with bone marrow transplantation in two children and to bronchiolitis obliterans, bronchopulmonary dysplasia, interstitial pneumonitis, and Langerhans cell histiocytosis in four others. Thirteen children underwent lung transplantation and concomitant cardiac repair. Bilateral lung transplantation, ventricular septal defect closure and pulmonary homograft reconstruction of the right ventricular outflow tract to the transplanted lungs was performed in three children by means of a new technique that avoids the need for combined heart-lung transplantation. Two patients had ventricular septal defect closure and single lung transplant for Eisenmenger's syndrome, two had ligation of a patent ductus arteriosus and transplantation, three additional children underwent atrial septal defect closure and lung transplantation, and two underwent lung transplantation for congenital pulmonary vein stenosis. Eight early deaths and three late deaths occurred (actuarial 1-year survival 62%). Lung transplantation in children has been associated with acceptable early results, although modification of the adult implantation technique has been necessary. Lung transplantation and repair of complex congenital heart defects is possible; heart-lung transplantation may only be required for patients with severe left heart dysfunction and associated pulmonary vascular disease. Bronchiolitis obliterans remains a major concern for long-term graft function in pediatric lung transplant recipients. 相似文献

BACKGROUND: Patients with pulmonary atresia, ventricular septal defect, and major aortopulmonary collateral arteries have traditionally required multiple unifocalization staging operations before undergoing complete repair. Recently, the feasibility of a single-stage unifocalization and repair was demonstrated by Hanley. In this report, we describe our experience with each approach. METHODS AND RESULTS: Since 1989, 11 of 12 patients with pulmonary atresia, ventricular septal defect, and major aortopulmonary collateral arteries have undergone complete surgical correction. The first seven patients were subjected to staged bilateral unifocalizations, with repair being achieved in six (group I). The last five patients have undergone a single-stage midline unifocalization and repair via a sternotomy (group II). Four of these were infants (2 weeks to 9 months) and one was 13 years old. All patients in group I had tetralogy of Fallot, whereas in group II three patients had tetralogy of Fallot, one patient had double-outlet right ventricle, and one patient had complete atrioventricular canal and transposition. In group I, the median age at the first operation was 43 weeks. Complete repair was performed at a median age of 3.5 years, with a mean number of 3.3 operations required. In group II, only one operation was required to achieve complete repair at a median age of 28 weeks. The postoperative right ventricular/left ventricular pressure ratio was 0.49 in group I and 0.45 in group II. One intraoperative death and one late death occurred in group I and no early or late deaths in group II. Currently, four patients in group I and all five patients in group II are alive and well. CONCLUSIONS: Early intervention with both surgical approaches can lead to complete biventricular repair in most patients. Because the single-stage midline unifocalization and repair can achieve a completely repaired heart in infancy with one operation, it is currently our approach of choice. 相似文献

BACKGROUND: Minimally invasive pediatric cardiac surgical techniques continue to evolve and remain challenged by technologic advances in percutaneous devices developed to treat congenital heart disease exclusive of cardiopulmonary bypass. Public tenacity for "incisionless" operations, however, must remain balanced scrupulously against the collective safety of the surgical procedure. METHODS: Twenty-three pediatric patients underwent repair of atrial septal defects through a partial sternal split and a limited skin incision (5 to 7 cm) at our institution between July 1995 and October 1996. RESULTS: The average age of the patients was 6 years and 2 months (range, 19 months to 15 years) and the average weight was 23.3 kg (range, 11.3 to 61.7 kg). The average bypass time was 35 minutes (range, 19 to 81 minutes). Fourteen patients had a single dose of blood cardioplegia administered, whereas 9 had ventricular fibrillation electrically induced. Twenty-two patients had ostium secundum defects and 1 had a sinus venosus defect. The average length of the hospital stay was 3.6 days (range, 3 to 6 days). There were no operative or late deaths. CONCLUSIONS: Modifications of this technique continue to evolve as an effective cosmetic alternative to submammary and thoracotomy approaches. Advantages of this modification include excellent cosmetic results in all age groups and the concomitant security and familiarity of mediastinal access and full sternotomy when required. 相似文献

BACKGROUND: There are few congenital anomalies of the heart that have benefited more from thorough anatomic analysis than the complex anomaly known as atrioventricular septal defect in the setting of common atrioventricular junction. Recent advances in understanding the anatomy of this lesion have led to alternative methods of repairing these defects. METHODS: The medical records of 21 consecutive patients undergoing repair of complete atrioventricular septal defect have been reviewed. Nine of these patients had a standard one- or two-patch repair, and 12 had direct closure of the ventricular element of the defect. RESULTS: Direct closure resulted in significantly shorter pump and cross-clamp times. Follow-up for an average of 34 months suggests that when direct closure can be performed, the results are comparable with those of the more standard technique. CONCLUSIONS: Our initial success with this approach is encouraging; however, longer follow-up is required to establish whether it will be broadly applicable. 相似文献

CONTEXT: The incidence of infective endocarditis after surgical repair of congenital heart defects is unknown. OBJECTIVE: To determine the long-term incidence of endocarditis after repair of any of 12 congenital heart defects in childhood. DESIGN: Population-based registry started in 1982. SETTING: State of Oregon. PARTICIPANTS: All Oregon residents who underwent surgical repair for 1 of 12 major congenital defects at the age of 18 years or younger from 1958 to the present. MAIN OUTCOME MEASURE: Diagnosis of infective endocarditis confirmed by hospital or autopsy records. RESULTS: Follow-up data were obtained from 88% of this cohort of 3860 individuals through 1993. At 25 years after surgery, the cumulative incidence of infective endocarditis was 1.3% for tetralogy of Fallot, 2.7% for isolated ventricular septal defect, 3.5% for coarctation of the aorta, 13.3% for valvular aortic stenosis, and 2.8% for primum atrial septal defect. In the cohorts with shorter follow-up, at 20 years after surgery the cumulative incidence was 4.0% for dextrotransposition of the great arteries; at 10 years, the cumulative incidence was 1.1% for complete atrioventricular septal defect, 5.3% for pulmonary atresia with an intact ventricular septum, and 6.4% for pulmonary atresia with ventricular septal defect. No children with secundum atrial septal defect, patent ductus arteriosus, or pulmonic stenosis have had infective endocarditis after surgery. CONCLUSION: The continuing incidence of endocarditis after surgery for congenital heart defect, particularly valvular aortic stenosis, merits education about endocarditis prophylaxis for children and adults with repaired congenital heart defects. 相似文献

A 60-year-old patient underwent triple coronary artery bypass grafting following an inferoseptal myocardial infarction and early onset of exertional angina. Four years later he was involved in a car accident during which he sustained an abdominal and thoracic trauma. Approximately 1 month after discharge, a ventricular septal defect was diagnosed by two-dimensional Doppler echocardiography with patency of all grafts at coronary angiography. Closure of the septal defect was successfully accomplished through a right atrial approach. Rupture of the ventricular septum following blunt chest trauma in a patient with previous myocardial revascularization has not been previously reported. 相似文献

OBJECTIVE: Cardiological and general health status 3-9 years after neonatal arterial switch operation for transposition of the great arteries should be evaluated by non-invasive methods. METHODS: A total of 77 unselected children with intact ventricular septum (75.3%) or ventricular septal defect (24.7%) without or with aortic isthmic stenosis (5.2%) were prospectively examined 3.2-9.4 years (5.4 +/- 1.6) after neonatal switch. Clinical pediatric and cardiological examination, standard and 24 h Holter electrocardiogram, M-mode, 2D-, Doppler and colour Doppler echocardiography were performed. Outcome data were compared to published normals. RESULTS: Reoperation rate was 2.6%, 96.1% were without limitation of physical activity and 98.7% without medication. Compared to normals, growth was adequate, weight and head circumference were slightly reduced. After median sternotomy, 23.4% had abnormal thoracic configuration (16.9% asymmetry, 6.5% funnel chest). ECG and Holter: 93.5% were in sinus, 6.5% in ectopic atrial or junctional rhythm. Incidence of complete right bundle branch block was 15.8% in patients with ventricular septal defect and 5.2% in those without. Ischemic ST-T changes during exercise due to coronary artery occlusion and evidence of old myocardial infarction were found in 1 patient (1.3%) each. Occasional atrial ectopy was found in 27.4%, ventricular ectopy in 15.3%: occasional in 12.5% and frequent (> 30/h) in 2.8% presenting bigemini, couplets and short runs of ventricular tachycardia at rest and during exercise. Echocardiography: Left ventricular function was normal in all. Endsystolic diameter of neoaortic valve annulus was beyond 90% confidence interval for controls in 79.2%, neoaortic root diameter in 100%. Mild aortic insufficiency was seen in 10.4%. No correlation was found between aortic insufficiency and aortic dilatation. Neoaortic stenosis was not seen, mild residual coarctation after end-to-end-anastomosis was found in 2.6%, native coarctation corrected later on in 1.3%. Supravalvular pulmonary stenosis was seen in 29.9% (19.5% trivial, 7.8% mild, 2.6% moderate), mild subvalvular pulmonary stenosis in 1.3%, pulmonary insufficiency in 2.6%. CONCLUSION: The study confirms good midterm results after neonatal arterial switch operation for transposition with or without ventricular septal defect. Long-term observation is necessary to assess rhythm, coronary artery and myocardial function as well as development of neo-aorta and pulmonary artery system. 相似文献

Infants born in New England with congenital heart defects were examined for association with time of year or population density. Moderate seasonal peaks in births were noted for complex ventricular septal defect, malposition defects, and transposition of the great arteries. Positive associations with population density were found for pulmonary atresia with ventricular septal defect, ventricular septal defect with secondary anomalies, and tricuspid atresia. 相似文献

An alternative approach for correction of supracardiac (type I) total anomalous pulmonary venous return is described. A median sternotomy is used. The posterior wall of the left atrium and the common pulmonary venous trunk are exposed through the transverse sinus. A direct anastomosis between these structures, ligation of the systemic-venous connection (vertical vein), and closure of the interatrial septal defect results in a one-stage repair. In our experience with the supracardiac anomaly in 20 patients, we have found that this approach consistently affords better exposure than other techniques currently in use for surgical correction of this anomaly. 相似文献

An echocardiographical and clinical pathological investigation of the rapid loss of weight by a yearling thoroughbred filly revealed an atrial septal defect, a ventricular septal defect and hyperfibrinogenaemia. A post mortem examination confirmed the cardiac abnormalities and revealed a severe thoracic aortitis. It is proposed that the idiopathic thoracic aortitis contributed to the horse's compromised cardiovascular homoeostasis. 相似文献

Neonates with ventricular septal defect and aortic arch obstruction frequently have subaortic stenosis resulting from posterior deviation of the infundibular septum. Because the aortic anulus is often hypoplastic, making direct resection of the infundibular septum through the standard transaortic approach difficult, the optimal method of repair is uncertain. From September 1989 through November 1991, seven patients with ventricular septal defect, coarctation (n = 4), or interrupted aortic arch (n = 3) and severe subaortic stenosis underwent repair with use of a technique that included transatrial resection of the infundibular septum. Their ages ranged from 5 to 63 days (median 15 days) and weights from 1.3 to 5.4 kg (mean 3.1 kg). Only one patient was older than 1 month. The systolic and diastolic ratios of the diameter of the left ventricular outflow tract to that of the descending aorta were 0.53 +/- 0.09 mm (standard deviation) and 0.73 +/- 0.11, respectively. At operation, the posteriorly displaced infundibular septum was partially removed through a right atrial approach by resecting the superior margin of the ventricular septal defect up to the aortic anulus. The resulting enlarged ventricular septal defect was then closed with a patch to widen the subaortic area. In each patient the aortic arch was repaired by direct anastomosis. All patients survived operation; there was one late death from noncardiac causes 3 months after repair. The survivors remain well from 3 to 14 months after repair (mean 8 months). All are in sinus rhythm and none has a residual ventricular septal defect. One patient underwent successful balloon dilation of a residual aortic arch gradient late after repair. No patient has significant residual subaortic stenosis, although one has valvular aortic stenosis. This series suggests that in neonates with ventricular septal defect and severe subaortic stenosis resulting from posterior deviation of the infundibular septum, direct relief can be satisfactorily accomplished from a right atrial approach. This method provides effective widening of the left ventricular outflow tract and is superior to palliative techniques or conduit procedures. 相似文献

BACKGROUND: Our surgical strategy for infant coarctation changed from subclavian flap aortoplasty to resection with extended end-to-end anastomosis in 1991. The purpose of this review was to evaluate the results of that strategy. METHODS: From 1991 through 1997, 55 infants underwent repair of coarctation of the aorta using resection with extended end-to-end anastomosis. Isolated coarctation of the aorta was present in 26 patients, 20 patients had a ventricular septal defect, and 9 patients had other associated intracardiac lesions. Mean age at surgery was 0.20+/-0.24 years (median, 21 days). In 34 patients (62%), arch reconstruction was performed through a left thoracotomy. Twenty patients (36%) had median sternotomy with simultaneous repair of coarctation of the aorta and intracardiac repair of associated lesions. One patient had recoarctation repair through a median sternotomy. All coarctation and ductal tissue was resected and the anastomosis was constructed starting opposite the left carotid artery with running polypropylene suture. RESULTS: There was one early death 26 days after coarctation of the aorta and ventricular septal defect repair in a child on extracorporeal membrane oxygenation for meconium aspiration and 2 late deaths owing to pneumonia and pulmonary hypertension (1) and interventricular hemorrhage (1). There were no instances of paraplegia. Follow-up in survivors ranges from 10 to 76 months (mean, 39.8+/-17.2 months). Recoarctation has developed in 2 patients, who have had successful balloon dilation 6 and 14 months after the operation. This yields a low recoarctation rate of 3.6%. CONCLUSIONS: Resection with extended end-to-end anastomosis yields a low mortality and particularly a low recoarctation rate and is our procedure of choice for infants with coarctation of the aorta. 相似文献

Tetralogy of Fallot was diagnosed in an acyanotic 11-month-old dog. Predicted pressure gradient across the pulmonic valve, as assessed by use of continuous wave Doppler echocardiography, was 94.5 mm Hg. Bidirectional shunting was identified by means of selective angiography. Open-heart correction was performed, using a transatrial approach with limited ventriculotomy and cardiopulmonary bypass. The hypertrophied infundibulum was resected, the ventricular septal defect was closed primarily, and a transannular pericardial patch graft was applied. Pressure gradients across the pulmonic valve were 52.9 and 22.8 mm Hg 2 weeks and 4 months after surgery, respectively. Advances in cardiopulmonary bypass, anesthetic management, and use of the transatrial approach may improve the success of open-heart correction of tetralogy of Fallot in dogs. 相似文献

BACKGROUND: For many congenital heart defects, hospital mortality is no longer a sensitive parameter by which to measure outcome. Although hospital survival rates are now excellent for a wide variety of lesions, many patients require expensive and extensive hospital-based services during the perioperative period to enable their convalescence. These services can substantially increase the cost of care delivery. In today's managed care environment, it would be useful if risk factors for higher cost could be identified preoperatively so that appropriate resources could be made available for the care of these patients. The focus of this retrospective investigation is to determine if risk factors for high cost for repair of congenital heart defects can be identified. METHODS: We assessed financial risk by tracking actual hospital costs (not charges) for 144 patients undergoing repair of atrial septal defect (58 patients), ventricular septal defect (48 patients), atrioventricular canals (14 patients), or tetralogy of Fallot (24 patients) at Duke University Medical Center between July 1, 1992, and September 15, 1995. Furthermore, we were able to identify where the costs occurred within the hospital. Financial risk was defined as a large (> 60% of mean costs) standard deviation, which indicated unpredictability and variability in the treatment for a group of patients. RESULTS: Cost for atrial septal defect repair was predictably consistent (low standard deviation) and was related to hospital length of stay. There were factors, however, for ventricular septal defect, atrioventricular canal, and tetralogy of Fallot repair that are identifiable preoperatively that predict low- and high-risk groups using cost as an outcome parameter. Patients undergoing ventricular septal defect repair who were younger than 6 months of age at the time of repair, who required preoperative hospital stays of longer than 7 days before surgical repair, or who had Down's syndrome had a less predictable cost picture than patients undergoing ventricular septal defect repair who were older than 2 years, who had short (< 4 days) preoperative hospitalization, or who did not have Down's syndrome ($48,252 +/- $42,539 versus $15,819 +/- $7,219; p = 0.008). Patients with atrioventricular canals who had long preoperative hospitalization (> 7 days), usually due to pneumonia (respiratory syncytial virus) with preoperative mechanical ventilation had significantly higher cost than patients with atrioventricular canals who underwent elective repair with short preoperative hospitalization ($83,324 +/- $60,138 versus $26,904 +/- $5,384; p = 0.05). Patients with tetralogy of Fallot had higher costs if they had multiple congenital anomalies, previous palliation (combining costs of both surgical procedures and hospital stays), or severe "tet" spells at the time of presentation for operation compared with patients without these risk factors ($114,202 +/- $88,524 versus $22,241 +/- $7,071; p = 0.0005). One patient (with tetralogy of Fallot) with multiple congenital anomalies died 42 days after tetralogy of Fallot repair of sepsis after a gastrointestinal operation. Otherwise, hospital mortality was 0% for all groups. CONCLUSIONS: Low mortality and good long-term outcome for surgical correction of congenital heart defects is now commonplace, but can be expensive as some patients with complex problems receive the care necessary to survive. This study demonstrates that it is possible to identify factors preoperatively that predict financial risk. This knowledge may facilitate implementation of risk adjustments for managed care contracting and for strategic resource allocation. 相似文献
