我们为一位47岁患者成功的施行了国内首例TMLR+CABG手术。病人为严重广泛三支病变伴左心衰,LVEF27%,激光在左室壁打孔46个,搭桥4根,病人术后恢复顺利,症状消失、心功能明显改善,术后二周痊愈出院。  相似文献

目的评价Starclose血管缝合器在老年冠状动脉介入诊疗术中使用的安全性和疗效。方法204例老年冠脉介入诊疗术后患者,110例应用Starclose缝合器止血(缝合组),94例应用手工压迫止血方法止血(对照组),分别记录止血时间、下肢制动时间和手术相关并发症。结果缝合组与对照组的止血成功率无统计学差异(P>0.05);缝合组的止血时间及下肢制动时间明显较对照组缩短(P<0.01);对照组手术相关并发症发生率明显高于缝合组(P<0.05)。结论Starclose血管缝合器在老年冠状动脉介入诊疗中具有良好的临床效果和安全性。  相似文献

The effects of background millimeter radiations (BMR) in patients with coronary artery disease (CAD), hypertension and in subjects with Inherited real risk of CAD, were investigated through invariant statistic measures, typical of nonlinear dynamics analysis of biological systems. The experimental evidences show that BMR ameliorate the nonlinear complexity in biosystems, recognized sign of physiological behavior, by increasing both the rate of unpredictability of heart rate variability (HRV) in patients with metabolic syndrome and the fractal dimension of coronary microvessel oscillations in subjects with pre-metabolic syndrome, healing their genetic alteration and CAD Inherited real risk.  相似文献

Physicians are demanding innovative technologies for multimodal imaging of the cardiovascular system that would lead to the appearance of advanced diagnosis and therapy procedures. This implies the simultaneous development of new imaging techniques and contrast agents whose synergy would make it possible. Optical coherence tomography (OCT) has recently emerged as a versatile and high‐resolution clinical technique for cardiovascular imaging. Unfortunately, the lack of adequate contrast agents impedes the use of OCT for intracoronary multimodal imaging. In this work, the hitherto unexplored capability of semiconductor quantum dots (IR‐QDs) emitting in the third infrared biological window (1.55–1.87 µm) to act as multimodal agents for intracoronary imaging is demonstrated. Under single line laser excitation at 1.3 µm, IR‐QDs are capable of providing simultaneous backscattering contrast and efficient luminescence at 1.6 µm. In this work, backscattered radiation is successfully employed to construct OCT images in both fluids and tissues whereas the infrared luminescence of the IR‐QDs provides the possibility for simultaneous acquisition of high penetrating fluorescence images. The first multimodal (fluorescence + OCT) imaging of an artery using IR‐QDs as contrast agents is provided herein demonstrating their outstanding potential for future clinical applications.  相似文献
