Percutaneous echocardiographically guided pericardiocentesis in pediatric patients: evaluation of safety and efficacy

The purpose of this study was to evaluate the safety and efficacy of echocardiographically (echo) guided pericardiocentesis in pediatric patients. Echo-guided pericardiocenteses performed in pediatric patients (age >/=16 years) at the Mayo Clinic between 1980 and 1997 were identified. Presentation, cause and characteristics of the effusion, details of the pericardiocentesis procedure, and outcome were determined by comprehensive chart review supplemented by telephone interviews when necessary. Seventy-three pediatric patients, median age 6.7 years (range 1 day to 16 years), underwent 94 consecutive echo-guided pericardiocenteses for effusions of various causes. Twenty-one (22%) procedures were performed in children younger than 2 years. All but 1 procedure were successful (99%). A mean fluid volume of 237 mL (range 4 to 970 mL) was withdrawn. Only a single attempt was needed for entry into the pericardial space in 87 (93%) procedures. No deaths were associated with the pericardiocentesis procedure. Only 1 major complication occurred (1%), a pneumothorax requiring chest tube reexpansion. Three (3%) minor complications-2 instances of right ventricular puncture and a small pneumothorax-did not require treatment. Extended catheter drainage for a mean of 5.2 +/- 4.5 days (range 1 to 19 days) was used with 30 (32%) of the 94 procedures. For the 52 patients who underwent pericardiocentesis without catheter drainage as the initial management strategy, 18 required 21 repeat pericardiocenteses for recurrence of effusion. In contrast, for the 21 patients who had pericardial catheterization as the initial management strategy, none had recurrences necessitating a repeat procedure (P <.001). Increased utilization of a pericardial catheter was associated with a concomitant decrease in the number of surgical pericardial procedures over the study period. Echo-guided pericardiocentesis was the only therapeutic modality for the management of effusion in 73% of all patients. Echo-guided pericardiocentesis is safe and effective in pediatric patients, including children younger than 2 years. The increasing use of pericardial catheterization in conjunction with this technique was associated with significant reduction of recurrence and decreased frequency of surgical interventions for treatment of pericardial effusion. Echo-guided pericardiocentesis with extended catheter drainage should be considered as primary management strategy for clinically significant pericardial effusions in pediatric patients.     

Cardiac tamponade in the pediatric oncology population: treatment by percutaneous catheter drainage

PURPOSE: The treatment of pericardial effusion resulting in cardiac tamponade has undergone an evolution in recent years, with the use of less invasive drainage methods in selected cases. To determine optimal therapy for pediatric oncology patients with pericardial effusion and tamponade, the authors reviewed their institutional experience with percutaneous catheter drainage. METHODS: Patient records and operative reports were reviewed, and nine patients were identified who met clinical and echocardiographic criteria of cardiac tamponade and were treated with percutaneous pericardial catheter drainage. RESULTS: The median age at time of diagnosis was 14 years (range, 5 months to 19 years), and the male:female ratio was 7:3. Underlying malignancies included acute myeloblastic leukemia in three, acute lymphoblastic leukemia in one, and Hodgkin's disease, B-cell lymphoma, medulloblastoma, desmoplastic small round cell tumor, and rhabdomyosarcoma in one each. EIght patients (89%) were receiving granulocyte colony-stimulating factor (GCSF) during the period when tamponade developed. All patients had a large or moderate-to-large pericardial effusion and right ventricular collapse with hemodynamic compromise on echocardiography, and two patients (22%) also had pericardial thickening. In nine patients, percutaneous catheter drainage was performed intraoperatively and under fluoroscopic or echocardiographic guidance. A median of 300 mL (range, 82 to 500 mL) of fluid was removed from the pericardial sac during the initial drainage, and cytology was positive in one (6%). Complete echocardiographic resolution was observed in eight patients (89%); a small posterior component persisted in one patient but was not significant hemodynamically. The catheters remained in place for a median of 5 days (range, 1 to 35 days) while repeat aspirations were performed. Tamponade resolved in all patients, and one died of overwhelming systemic sepsis. The survival period was 10 to 22 months, and tamponade or the drainage procedure did not contribute to death. Four patients remain alive after 4 month to 7 years of follow-up. CONCLUSION: Cardiac tamponade was effectively treated in all patients and did not recur with percutaneous catheter drainage alone. THere was no evidence of pericardial loculation or infection despite pancytopenia being prevalent with underlying illness and chemotherapy. Percutaneous catheter drainage is an effective treatment for pediatric oncology patients with pericardial tamponade. Because of its simplicity in comparison to move invasive techniques, initial treatment with percutaneous drainage should be considered in this patient population.     

Familial Wilms'' tumor associated with a WT1 zinc finger mutation

Cardiac metastasis from gynecological malignancies is rare. Only six cases of carcinoma of the uterine cervix have been reported where the diagnosis of malignant pericardial effusion was made antemortem. The treatment of neoplastic pericardial effusion is controversial; both surgical and nonsurgical treatments are advocated. We present a patient with pericardial effusion secondary to carcinoma of the cervix and recommend subxiphoid pericardial fenestration for reliable long-term control of malignant effusion.     

Pleurodesis with iodized talc for malignant effusions using pigtail catheters

OBJECTIVE: To assess the efficacy of using an iodized talc slurry as a sclerosing agent instilled into the pleural space via a 12-French pigtail catheter for controlling malignant pleural effusions. DESIGN: A prospective study in which patients were followed until their death. SETTING: A university-affiliated tertiary-care teaching hospital. PATIENTS: Medical oncology patients admitted with symptomatic malignant pleural effusions were considered for iodized talc pleurodesis. MAIN OUTCOME MEASURES: The control of pleural effusion. Treatment failure was defined as any reaccumulation of fluid in the pleural space. RESULTS: Fifteen patients were treated for a total of 17 instillations. The median follow-up on all patients until death was 6 months (range 1-20). The most frequent adverse effect in the study group was pleuritic chest pain (60%). The probability of control of effusion, as determined by the method of Kaplan-Meier, was 81% (SEM 9.7%). The cost of preparing 5 g of iodized talc was $4.32 (US). CONCLUSIONS: Iodized talc slurry instilled through a small-bore pigtail catheter is a safe, economical, and effective treatment for malignant pleural effusion.     

Potent HIV protease inhibitors incorporating high-affinity P2-ligands and (R)-(hydroxyethylamino)sulfonamide isostere

We performed percutaneous balloon pericardiotomy and pulmonary valvuloplasty in a woman affected with cardiac and pericardial involvement from a primary pulmonary adenocarcinoma. Pericardial window was indicated for a recurrent, symptomatic, pericardial effusion. Valvular stenosis was severe and related to metastatic infiltration of cardiac tissue. Open surgery was avoided and the procedures were completed in two steps under local anesthesia in less than 60 min. The patient had no recurrence of pulmonary stenosis or pericardial effusion at 7 months post treatment. Transcatheter techniques are successful in helping to manage malignant diseases with cardiac metastasis, particularly in critically-ill patients. It may become the preferred treatment for avoiding a more invasive procedure for patients with a limited life expectancy.     

European Consensus Statement on Neonatal Hearing Screening. Finalised at the European Consensus Development Conference on Neonatal Hearing Screening, 15-16 May 1998, Milan

Lyme disease is well known for affecting the myocardium in the form of carditis and dilated cardiomyopathy. Pericardial effusion associated with Lyme disease has not been described as yet. This article demonstrates a case of a female patient, 54 years of age, with Borrelia burgdorferi infection and associated pericardial effusion. Recurrent pericardiocenteses as well as conventional treatment of the condition were without success. Diagnosis of Borrelia infection and subsequent treatment with ceftriaxone led to permanent restitution of the pericardial effusion.     

Pericardial effusion after primary percutaneous transluminal coronary angioplasty in first Q-wave acute myocardial infarction

To evaluate the incidence and clinical significance of infarction-associated pericardial effusion in patients with successful primary percutaneous transluminal coronary angioplasty, we studied 214 consecutive patients with a first Q-wave acute myocardial infarction. Based on 9 clinical variables, multivariate analysis was performed to determine the important variables related to the occurrence of pericardial effusion. Pericardial effusion was detected by echocardiography in 45 patients (21%); pericardial rub (p <0.001), number of advanced asynergic segments (p <0.001), ventricular aneurysmal motion (p = 0.03), and pulmonary capillary wedge pressure (p = 0.04) were found to be the important variables related to pericardial effusion. Among 45 patients with pericardial effusion, 29 patients with no pericardial rub had significantly higher pulmonary capillary wedge pressure than those with pericardial rub, whereas 16 patients with pericardial rub had a higher incidence of angiographic no reflow and ventricular aneurysmal motion than those without pericardial rub. Patients with pericardial effusion and a pericardial rub had a higher mortality rate than those without pericardial effusion (19% vs 3%; p = 0.02). Thus, pericardial effusion is still a relatively common clinical finding after primary percutaneous transluminal coronary angioplasty, and those with pericardial effusion and a pericardial rub were associated with more severe transmural myocardial damage and higher in-hospital mortality.     

The evaluation of carcinoembryonic antigen determination in the pericardial fluid in the diagnosis of the cause of pericarditis

Pericardial fluid CEA level was measured with radioimmunoassay in 19 patients with large pericardial effusion of unknown origin. In 11 patients malignancy was diagnosed. In all of these patients pericardial fluid CEA levels were above 7 ng/ml (mean value 52.6 +/- 42.6 ng/ml). In 8 patients the etiology of pericarditis was non-malignant. In all of them pericardial fluid CEA levels were below 7 ng/ml (mean value 2.2 +/- 1.6 ng/ml). In 9 patients with malignant pericarditis serum CEA levels were also determined: they were found to be lower than pericardial fluid CEA values in 6 patients. It was concluded that pericardial fluid CEA elevation is a reliable criteria of neoplastic pericardial involvement.     

Surgical treatment of chronic pericardial effusions. Personal experience

The authors report their experience about 15 patients surgically treated for chronic large pericardial effusion; in 12 cases the etiology was malignant neoplasm, while in the other 3 cases was inflammatory disease. In 4 patients a simple subxiphoid pericardial drainage was carried out, while in the other cases a pericardial window was performed. These cases were managed using an anterior left thoracotomy in 8 patients and a videothoracoscopy in 3. The authors conclude that pericardial window with videothoracoscopic approach is the preferable procedure, but it cannot be used in every case because a lot of patients have seriously compromised conditions and the use of this technique can be hazardous.     

Ascites, pleural, and pericardial effusions in acute pancreatitis. A prospective study of incidence, natural history, and prognostic role

Ascites and pleural and pericardial effusions can be observed during acute pancreatitis. The aims of this study were to evaluate their incidence, natural history, and prognostic role in patients with acute pancreatitis. One hundred patients consecutively admitted with a diagnosis of acute pancreatitis were prospectively submitted to abdominal, pleural, and cardiac ultrasonography at admission and during follow-up. Ascites was found in 18 patients, pleural effusion in 20, and pericardial effusion in 17. Twenty-four patients of this series had severe pancreatitis; three of them died. All effusions disappeared spontaneously in patients who survived pancreatitis up to two months after dismissal. At multivariate analysis ascites and pleural effusion were demonstrated to be accurate independent predictors of severity. The respective odds ratios were 5.9 [95% confidence interval (CI), 1.5-23.0%) and 8.6 (95% CI, 2.3-32.5%). Furthermore the presence of pleural effusion, ascites, and pericardial effusion were associated with an increased incidence of pseudocyst during follow-up. Ascites and pleural and pericardial effusions are frequent during acute pancreatitis. Pleural effusion and ascites are accurate predictors of severity in these patients.     

Catheter lavage and drainage of pneumococcal pericarditis

An 88 year old woman with streptococcal pneumonia developed purulent pericarditis and cardiac tamponade despite treatment with antibiotics. Percutaneous pericardial drainage was effected with a 6 French pigtail catheter inserted via the subxyphoid approach. Catheter drainage was continued for 7 days in conjunction with systemic antibiotics. Catheter patency was maintained with antibiotic lavage. Immediate hemodynamic improvement followed the initial pericardial drainage. Fever, leukocytosis, and sepsis resolved during the course of therapy. The patient recovered fully from the closed space bacterial infection without additional surgical drainage. There has been no recurrence of streptococcal infection and no echocardiographic evidence of recurrent pericardial effusion after 3 months of follow-up. Indwelling catheter drainage combined with antibiotics may be an effective substitute for surgical drainage in the treatment of streptococcal pericarditis.     

N,N-dimethyldioncophyllinium A iodide: synthesis, stereoanalysis, and antimalarial activity of the first N-quaternary naphthylisoquinolinium salt

Since the reported incidence of pericardial effusion following thrombolysis is highly variable, we have evaluated 80 consecutive patients with first acute myocardial infarction treated with streptokinase. Two-dimensional echocardiographic studies were performed on days 1, 2, 3, and 7, at 3 and 6 weeks, and 3, 6, and 12 months following acute myocardial infarction. Throughout the study, pericardial effusion was found in 7 of 80 (8.75%) patients, being small in 5 patients, moderate in 1, and large in 1 patient. No clinical, angiographic, or echocardiographic variable was associated with pericardial effusion formation. The incidence of pericardial effusion found in our study is almost three times lower than in other echocardiographic studies on pericardial effusion in thrombolysed patients. Whether this differences results from the beneficial effects of streptokinase is not clear.     

Pericardial thickening or effusion in patients with pulmonary artery hypertension: a CT study

OBJECTIVE: The aim of the study was to determine the prevalence of pericardial thickening or effusion revealed by CT in patients with pulmonary artery hypertension. MATERIALS AND METHODS: Forty-five patients underwent pulmonary artery catheterization and CT of the thorax. On CT, we measured the maximum pericardial thickness, total pericardial score (the sum of four measures of pericardial thickness), and thickness of the anterior pericardial recess. Patients were grouped according to mean pulmonary artery pressure: group 1, less than 21 mm Hg (n = 15); group 2, 21-35 mm Hg (n = 15); and group 3, greater than 35 mm Hg (n = 15). RESULTS: The prevalence of an increased pericardial score and increased maximum pericardial thickening was higher in group 3 than in group 1 or group 2 (p = .02 and < .001, respectively). Anterior pericardial recess thickening was markedly increased in group 3 (p < .0001). For all patients, significant correlations (Spearman's rank correlation coefficient = .44-.56, p < .005-.0001) were found between mean pulmonary artery pressure and all pericardial measures. CONCLUSION: On CT, pericardial thickening or effusion is a frequent finding in patients with severe pulmonary hypertension.     

Two cases of tuberculous constrictive pericarditis

Case 1 was a 79-year-old male suspected of tuberculous constrictive pericarditis. He was admitted to our hospital because of surgical treatment. His heart failure was NYHA IV. Culture of pleural effusion and pericardial effusion was negative. But ADA level in pericardial effusion was found to be increased. So tuberculosis was suspected. Cardiac catheterization date was compatible with constrictive pericarditis. Case 2 was a 73-year-old female. She was admitted because of heart failure (NYHA IV). As RVP wave indicated dip & platou at cardiac catheterization, she was diagnosed as constrictive pericarditis. ADA level in pleural effusion increased. So tuberculosis was suspected as etiology of constrictive pericarditis. In both cases, after pericardiectomy, heart failure improved to NYHA I. Results of pathological examination were tuberculous inflammation.     

Endocardial activation mapping of ventricular tachycardia in patients : first application of a 32-site bipolar mapping electrode catheter

BACKGROUND: Localization of early activated endocardial areas during ventricular tachycardia (VT) is mandatory for performance of surgical or radiofrequency catheter interventions. The use of a multielectrode catheter may shorten the procedure time and increase the accuracy of the procedure compared with single-electrode mapping techniques. This study was performed to evaluate the safety and efficacy of a 32-bipolar-electrode mapping catheter in patients. METHODS AND RESULTS: The basket-shaped mapping catheter (BMC), integrated with a computerized mapping system, allowed on-line reconstruction of endocardial activation maps. Twenty patients with VT were studied before surgery (n=4) or radiofrequency catheter ablation (n=16). End-diastolic left ventricular (LV) volume was 280+/-120 mL, with an LV ejection fraction of 33+/-14%. The volume encompassed by the BMC was 164+/-27 mL (130 to 200 mL); the deployment time was 46+/-11 minutes. Endocardial activation time during sinus rhythm was 105+/-34 ms; 14+/-5 electrodes could be used to stimulate the heart. Cycle length of VT was 325+/-83 ms. Earliest endocardial activation was recorded 58+/-42 ms before the onset of the surface ECG. Complications were pericardial effusion (n=2) and transient cerebral disorientation (n=1). CONCLUSIONS: Percutaneous multielectrode endocardial mapping in patients with VT is feasible and relatively safe. The use of this technique shortens the time patients have to endure VT.     

The lateral chest radiograph in the detection of pericardial effusion: a reevaluation

The purpose of this study was to evaluate the usefulness of 10 previously published plain film signs for diagnosing pericardial effusion and to determine whether the posteroanterior (PA) or lateral chest radiograph was the better view for detecting pericardial effusion. A retrospective study of 100 consecutive adult patients with pericardial effusions confirmed by echocardiography and/or computed tomography was undertaken. Five signs were found to be useful in detecting pericardial effusion on plain films, and the lateral chest radiograph was found to be better than the PA view in detecting pericardial effusion. The water-bottle configuration, widening of the carinal angle, and the differential-density sign were helpful in diagnosing pericardial effusion on the PA view. However, these signs were only seen in moderate-to-large effusions. The displaced epicardial fat pad sign and the posteroinferior bulge sign on the lateral view improved the detection of moderate-to-large pericardial effusions, and were also present in many of the cases with small pericardial effusions. Recognition of specific signs of pericardial effusion on the lateral chest radiograph may significantly improve the plain film detection of pericardial effusion.     

Ultrasound-guided pericardial drainage. Experience in 34 consecutive patients

OBJECTIVES: Transthoracic echoguided puncture of the pericardium can be an alternative to surgical drainage. We report our experience with this technique acquired over the last 11 years. PATIENTS AND METHODS: From January 1984 to September 1995, 34 consecutive patients in the cardiology intensive care unit (mean age 56.5 +/- 13 years) underwent echoguided pericardial puncture for poorly tolerated pericardial effusion. The underlying cause was neoplasia (n = 22), idiopathic disease (n = 5), autoimmune disease (n = 2), post-surgical complication (n = 2 including 1 on hemodialysis), infection (n = 1), antivitamin K therapy (n = 1) and disseminated vascular coagulation (n = 1). The subxyphoid (n = 33) or left parasternal (n = 1) route was used under echographic guidance. Intrapericardial contrast allowed verification of the catheter position. The mean quantity of fluid removed was 585 +/- 390 ml. The fluid was hemorrhagic (n = 19), clear (n = 10) or serohematic (n = 4). Aspiration was continued in 16 patients after the initial puncture for a mean 64 hours. The mean total volume of fluid was 750 +/- 330 ml. RESULTS: There was one death during puncture which was found to be unrelated to the procedure after anatomic verification. In two cases, the left ventride was punctured without any consequence. Collapsus occurred during puncture in 2 patients with pulmonary sepsis. Minor incidents were: 6 vasovagal syndromes at puncture with paroxysmal supraventricular rhythm disorder during aspiration. Prior to 1988, surgical drainage was required in 5 patients for persistent or recurrent effusion. Since that time, continuous aspiration has been used in all patients and no surgical drainage has been required. Short-term prognosis depends on the underlying cause (6 deaths at 1 month). CONCLUSION: Echoguided pericardial puncture is a simple procedure which rapidly improves cardiac hemodynamics in these particularly fracle patients. Continuous aspiration avoids subsequent surgical drainage for persistent or recurrent effusion.     

Benign fibrous mesothelioma: report of 8 cases

Benign fibrous mesothelioma (BFM) is a primary, isolated tumor of the pleura. In 80% of patients the tumor originates in the visceral pleura. BFM is rare and localized malignant mesothelioma, whose prognosis and treatment is significantly different, must be considered as a differential diagnosis. We report 8 cases of BFM excised by thoracotomy. In 6 asymptomatic patients, diagnosis was based on radiological images. One patient with a large tumor suffered dyspnea, acropachia and hypertrophic osteoarthropathy. The last patient experienced long-lasting chest pain even though the tumor was small (3 x 3 x 1 cm). Diagnosis was before thoracotomy in 3 cases, 2 by punch biopsy (tru-cut) and the other by thoracoscopy. The results of pleural fluid analysis were nonspecific in 2 of the 3 cases in which pleural effusion was present. Thoracotomy allowed removal of the entire tumor in all patients.     

Controlled reopen suture technique for pyloric exclusion

The aim of this prospective, randomized study was to investigate the possibility of performing pleurodesis using a small percutaneous catheter (Cystofix catheter, CH10, 65 cm) inserted at bedside in patients with recurrent malignant pleural effusion and to compare this catheter with a conventional large bore chest tube (CH24) placed in connection with diagnostic thoracoscopy. After drainage pleurodesis was performed with tetracycline as sclerosing agent. Of 18 evaluable consecutive patients (mean age 67.8 years) nine were randomized for pleurodesis with the small and nine for the large catheter. In the former group, the majority (seven of nine) did not find insertion of the catheter more unpleasant than thoracentesis. In the latter group only a few (two of nine) found insertion comparable with thoracentesis (P < 0.05). All patients found the presence of the large catheter very or somewhat unpleasant (two and seven patients), whereas this was only the case for a few (no and two patients) treated with the small catheter (P < 0.05). In the former group three patients required new thoracentesis, whereas this was only the case for two patients in the latter group (P > 0.05). No complications were seen. We conclude that pleurodesis in patients with recurrent malignant pleural effusion can be performed with a small percutaneous catheter (Cystofix) with an effect similar to that obtained with a large-bore chest tube and with less discomfort for the patient.     

Reversal of intractable uremic pericarditis by triamcinolone hexacetonide

Of 74 patients undergoing long-term hemodialysis who were observed during a 21-month period, seven developed uremic pericarditis. Five of these patients developed intractable pericarditis, unresponsive to intensive dialysis and pericardiocentesis, and were treated with prolonged pericardial drainage (16 to 60 hours) by an indwelling polyethylene catheter and instillation of triamcinolone hexacetonide. Evidence of intractability was based on either the recurrence of cardiac tamponade after pericardiocentesis (two patients) or progression in the size of the pericardial effusion despite four weeks of intensive dialysis (three patients). These five patients recovered and subsequently were observed from 1 to 15 months with no evidence of recurrent pericarditis. This procedure may be an effective alternative to the surgical management of intractable uremic pericarditis, particularly in the patient at high risk for anesthesia and major surgery.
