冠状动脉钙化与冠状动脉狭窄的相关性研究

目的探究冠心病患者冠状动脉钙化积分与冠状动脉狭窄的相关性。方法入选54例冠心病住院患者,年龄52～84岁,（平均68.47±9.35）岁;其中男性36例,女性18例,行16层螺旋计算机断层扫描,计算冠状动脉钙化积分,并与冠状动脉造影进行比较,分析冠状动脉总钙化积分及各冠状动脉节段（共分16个节段）钙化积分与冠状动脉造影所示冠脉狭窄程度的相关性,同时分析冠状动脉总钙化积分与年龄的相关性。结果冠状动脉总钙化积分与年龄呈正相关（r=0.372,P=0.009）、冠状动脉总钙化积分仅与部分冠状动脉节段狭窄程度呈正相关：RA（1#）、LAD（7#）、D1（9#）、LCX（11#）,（相关系数、P值分别为：r=0.499,P〈0.01;r=0.431,P〈0.01;r=0.440,P〈0.01;r=0.469,P〈0.01）。冠状动脉各节段钙化积分与对应血管节段狭窄程度相关分析结果提示：RA（1#）、LM（5#）、LCX（11#）节段钙化积分与对应节段狭窄程度呈正相关。结论总冠状动脉钙化积分与年龄呈正相关,提示随年龄增长冠状动脉钙化发生率增加,但冠状动脉钙化积分仅在部分冠状动脉节段与狭窄程度呈正相关,且限于三支冠状动脉近段。     

一站式杂交技术与非体外循环下冠脉搭桥术治疗复杂冠心病的meta分析

目的用meta分析方法对一站式杂交技术与非体外循环下冠脉搭桥术治疗冠心病疗效的临床研究进行综合性定量研究。方法使用Cochrane系统评价方法,计算机检索EMBASE,Cochrane图书馆、中国知网、万方数据库、CBM,web of Science,scopus,Google scholar and Controlled Trails metaRegister,Pubmed及Medline等数据库的文献,收集有关比较一站式杂交技术和非体外循环下冠脉搭桥术治疗冠心病的对照研究实验,评价入选研究的质量。结果共纳入符合标准的文献5篇,共409例患者。Meta分析结果显示:杂交组手术时间长于传统组住院费用多于传统组(P0.05);机械通气时间、住ICU的时间住院时间失血量、输红细胞悬浮液量术后心肌梗死发生率明显低于传统组(P0.05)。杂交组的非计划再次手术、术后新发房颤发生率及随访期死亡发生率与传统组无统计学差异(P0.05),但是杂交组随访期主要心脏不良事件发生率低于传统组且重返工作或正常活动时间短于传统组(P0.05)。结论一站式杂交治疗复杂冠心病的疗效可能优于非体外循环下冠脉搭桥术。     

Pseudoaneurysm of coronary artery following rupture of coronary artery during coronary angioplasty.

Rupture of the coronary artery is a rare complication of percutaneous transluminal coronary angioplasty (PTCA). We describe a case of coronary artery rupture during PTCA resulting in the formation of a coronary artery pseudoaneurysm. The pseudoaneurysm was successfully treated by percutaneous spring-coil embolization of the coronary artery.     

Dual anterior descending coronary artery associated with coronary artery disease

The patient is a male with risk factors for coronary artery disease, who was referred for cardiac catheterization after acute myocardial infarction in the inferior wall. The patient underwent transluminal coronary angioplasty in the right coronary artery with successful stent implantation.     

Isolated single coronary artery with dual right coronary artery distribution

We present the case of a 76-year-old patient in whom coronary angiography, performed due to non-ST-segment elevation myocardial infarction, revealed an isolated single coronary (SCA) artery with dual right coronary artery (RCA) distribution. One RCA arose from the mid segment of the left anterior descending (LAD) artery and followed a prepulmonic course to the right, while the other RCA arose as the terminal extension of the left circumflex artery beyond the crux cordis. This is the second reported case of the combination of these two variants of SCA and the first such case in which the LAD-derived RCA originated as a single branch. Furthermore, this is the first report presenting a sinus node artery with origin from an ectopic LAD-connected RCA. The clinical implications of this rare coronary artery pattern are discussed.     

重症冠心病的非体外循环下冠状动脉旁路移植术

目的 探讨如何提高莺症冠心病患者非体外循环下冠状动脉旁路移植术的手术疗效.方法 Off-Pump coronary artery bypass grafting of severe coronary artery disease回顾性分析268例重症冠心病患者非体外循环下冠状动脉旁路移植术的临床资料,男性131例,女性137例;搭桥数2～6(4.01±0.99)支/人.对手术方法、主要并发症和术后处理进行分析总结.结果 二次开胸3例(1.1%),低心排综合征9例(3.4%),应用IABP 1例(0.4%),反复发作房颤22例(8.2%),肺功能不全13例(4.9%);死亡2例(0.7%),其余患者康复出院.结论 合理地选择患者、成熟的手术技术、主动脉内球囊反搏(IABP)的尽早应用及术后处理的加强是提高重症冠心病患者非体外循环下冠状动脉旁路移植术疗效的重要措施.     

Robotic coronary artery bypass for aberrant right coronary artery stenosis

Anomalous coronary arteries that course between the aorta and pulmonary artery are subject to compressive forces and can manifest angina, myocardial infarction and sudden death. The current report presents a young, female patient who presented with a short duration of severe, rapidly progressive angina despite optimal medical therapy. Combined computed tomography and myocardial perfusion scanning identified an anomalous dominant right coronary artery that appeared kinked at its origin between the aorta and main pulmonary artery. A robot-assisted right internal thoracic artery to right coronary artery bypass was performed, which was confirmed to be widely patent (FitzGibbon grade A) on routine intraoperative angiography. The procedure completely resolved the patient's angina symptoms.     

Single coronary artery anomaly: branching of left coronary artery from right coronary artery with 2 distinct patterns

Normal coronary vasculature has a left coronary artery arising from the left coronary cusp and a right coronary artery arising from the right coronary cusp. In about 0.024% of cases in the general population, there is no left main coronary artery. In fact, there is a single coronary artery, which arises from the right coronary cusp. We encountered 2 such cases with distinct patterns. The first case was a patient with angina who had an abnormal stress test for which he underwent coronary angiography. This revealed a single coronary artery arising from the right coronary cusp. This vessel gave rise to the right coronary artery, which had a varicose anatomy, with a critical lesion in the posterior descending artery. The left coronary artery passed anteriorly to the pulmonary artery with a critical lesion in the circumflex artery. In the second case, the patient also had angina with a normal noninvasive work-up but due to his persistent symptoms, coronary angiography was performed. This revealed a single coronary artery arising from the right coronary cusp. Subsequent CT angiography revealed that the left coronary artery coursed in between the aorta and pulmonary artery without critical lesions. In both cases, the patients underwent coronary artery bypass grafting.     

冠状动脉外科发展史

冠状动脉搭桥手术（CABG）是当今冠心病治疗的重要手段之一。因其疗效好，再手术率低，已越来越多地被冠心病患者所接受。冠状动脉外科的发展是一个具有创造性思维的故事，期间有极大期望，亦有极大失望，但最终它产生了令人满意的结果。本文分5个阶段简述。
