目的 分析冠心病合并左室室壁瘤形成患者仅行冠状动脉旁路移植术(CABG)但未同期行左心室成形术的疗效。 方法 2008年1月至2012年12月武汉亚洲心脏病医院收治冠心病合并室壁瘤患者共105例,术中探查发现室壁瘤边界欠清或活动欠佳或无明显矛盾运动而未处理室壁瘤患者共74例,其中男59例,女15例;年龄 (60.96±9.09) 岁。冠状动脉造影显示:单支血管病变5例,双支病变10例,3支病变45例,左主干+3支病变14例。术中发现30例室壁瘤界限不清,29例心尖室壁变薄、室壁瘤不明显,15例室壁瘤未见明显的矛盾运动、心尖部质地较厚。所有患者均行冠状动脉旁路移植术。在体外循环下手术62例,非体外循环下手术12例。70例采用左乳内动脉吻合于左前降支,2例行左前降支内膜剥脱术。因二尖瓣中-重度反流行二尖瓣成形术3例,二尖瓣置换术2例;因合并主动脉瓣重度狭窄同期行主动脉瓣置换术1例。 结果 术后因恶性心律失常、缺血、缺氧性脑病死亡2例 (2.7%);因低心排血量、围术期心肌梗死、恶性心律失常等行主动脉内球囊反搏 (IABP) 辅助6例。术后随访70例,随访时间24~60 (43±12) 个月。随访期间发现心室内血栓形成8例,其中5例服用华法林1年内血栓消失,无1例发生血栓脱落栓塞事件。超声心动图检查提示:室壁瘤消失18例 (25.7%)。出院时、术后6个月、1年射血分数较术前明显增高 (术后6个月与术前比较:44%±6% vs. 39%±5%),左心室舒张期末内径 [术后6个月与术前比较:(54.37±6.28) mm vs. (59.24±6.24)mm]、左心室收缩期末内径与术前比较明显缩小 (P<0.01)。但随着时间延长,左心室舒张期末内径、左心室收缩期末内径较出院时逐渐增大。 结论 对于合并室壁瘤的冠心病患者,根据术中探查实际情况未行左心室成形术仅行冠状动脉旁路移植术,术后射血分数、左心室舒张期末内径、左心室收缩期末内径均较术前明显改善,但术后心室扩大呈进行性发展。  相似文献

目的评价单纯冠状动脉旁路移植术和同期加二尖瓣成形术对轻中度缺血性二尖瓣关闭不全(IMR)中期疗效的影响。方法1999年8月至2004年8月手术后生存的术前轻中度IMR病人60例,其中冠状动脉旁路移植术同期二尖瓣成形术(MVP组)和单纯冠状动脉旁路移植术(C组)各30例,分析术前资料,包括年龄、性别、二尖瓣反流程度、心功能、左心形态及左心室射血分数(LVEF)等,利用超声心动比较术后中期心功能和左心形态改善情况,利用生活质量评估表(SAQ量表)评价两组生活质量的改变。结果中期生存率MVP组为96.7%,C组为92.6%,两组差异无统计学意义。MVP组术后左心房内径缩小,C组左心房内径增大(P〈0.05),左心室内径改变两组差异无统计学意义。两组病人LVEF较术前均改善,但MVP组明显优于C组(P〈0.05)。MVP组术后生活质量明显优于C组病人,SAQ总得分分别为66.18和58.20(P〈0.05)。结论冠状动脉旁路移植术同期二尖瓣成形术可以明显提高轻中度IMR病人中期预后、生存率和生活质量,中期疗效优于单纯冠状动脉旁路移植术;  相似文献

Rupture of left ventricle following mitral valve replacement   总被引:5,自引:0,他引:5  
A survey of the English language literature revealed 125 cases of left ventricular rupture following mitral valve replacement. In ten larger series, the incidence averaged 1.2%. Most of the ruptures were attributed either to technical maneuvers in the operation or to stretch injury produced by the untethering of the left ventricle through removal of the mural leaflet of the mitral valve. Preventive measures include modifications in operative techniques, containing pressure-volume work by the left ventricle, and probably retention of the posterior mitral leaflet. Surgical repair of the rupture with and without the aid of cardiopulmonary bypass resulted in 50% and 7% survival, respectively. With the use of cardiopulmonary bypass, external repair was followed by a 67% survival and the internal approach, by a 27% survival.  相似文献

Posterior left ventricular rupture (LVR) is a serious complication following mitral valve replacement (MVR), especially if occurring postoperatively with the chest already closed or the patient in the intensive care unit. Only one of the patients with this delayed type of LVR reported earlier has been treated successfully. Our experience consists of 4 such complications among 161 MVR patients, the incidence being 2.5%. Two of these patients survived. Mechanical factors seem to constitute the most important etiologic causes for this complication. Immediate reoperation must be performed, and extracorporeal circulation is generally mandatory for successful repair. The reconstruction of the ruptured posterior left ventricular wall in both surviving patients was performed from the epicardial surface of the heart using pledget sutures. The auricle of the left atrium was used to cover the site of the tear when bleeding was not stopped with pledget sutures. It usually seems possible to avoid this complication if all mechanical etiologic factors are taken into consideration. After successful correction, a pseudoaneurysm may arise and, for that reason, a cardiac echo sonography follow-up is recommended.  相似文献

We report a rare case of infected left atrial myxoma associated with mitral valve endocarditis. The tumor and a small amount of vegetative growth on the anterior mitral leaflet were surgically excised. Subsequent antibiotic therapy may have prevented the infection from recurring. Histological findings showed myxoma cells embedded in mucinous stroma at the tumor base and an organized thrombus with bacterial colonization at the tumor tip.  相似文献

Delayed development of left ventricular pseudoaneurysm is a rare late complication of mitral valve prosthesis and requires early surgical intervention. Here we describe the occurrence of such a complication diagnosed 6-months after the valve surgery in a 60-year-old lady. The anatomic delineation of subannular left ventricular pseudoaneurysm using multiple imaging modalities including CT angiography is also being discussed.  相似文献

Reports of left atrial ball thrombus without mitral valve disease are few. We experienced a case of free-floating left atrial ball thrombus that developed in a short period in a patient with atrial fibrillation and dilated left atrium but intact mitral valve. Surgical removal of the thrombus was performed. It was presumed that atrial fibrillation and enlarged left atrium were the contributory factors to thrombus development.  相似文献

Systolic anterior motion of mitral anterior leaflet is a serious clinical condition and it is hard to control medically. Alfieri edge-to-edge repair has been thought one of the useful techniques to improve abnormal anterior systolic motion with hypertrophic obstructive cardiomyopathy. Here, we present a 71-year-old lady who had the left ventricular outflow tract obstruction, severe mitral valve regurgitation with systolic anterior motion. The patient had a history of aortic valve replacement 5 years ago. She was successfully treated with transaortic edge-to-edge mitral valve plasty and myectomy of the left ventricle. Postoperative course was uneventful.  相似文献

Rupture of the left ventricle in the atrioventricular (AV) groove is a rare and usually fatal complication of mitral valve replacement (MVR). The successful repair of a delayed type I left ventricular rupture is described. The technique of repair is described, the literature reviewed, and three further cases from the authors' experience are reported.  相似文献

OBJECTIVE: We studied whether differences exist between hearts having rheumatic mitral valves and those having myxomatous mitral valves, in functional, geometrical, and mass changes in the left ventricle after mitral valve replacement. METHODS: Patients who underwent mitral valve replacement without preservation of annular-papillary continuity for pure mitral incompetence were classified into rheumatic and myxomatous based on valvular histopathology. Echographic data measured before surgery was compared to that about 3 weeks after surgery. RESULTS: In the rheumatic group, ejection fraction decreased from 57.5 +/- 10.8 to 47.7 +/- 12.0, indexed left ventricular internal dimension in systole (mm/m2) from 24.7 +/- 6.8 to 20.7 +/- 6.2 (P = 0.0001), and left ventricular mass index (g/m2) from 205 +/- 55 to 138 +/- 54 (P = 0.0002). In the myxomatous group, ejection fraction decreased from 60.4 +/- 11.6 to 39.7 +/- 14.5 (P = 0.0001), indexed left ventricular internal dimension in systole from 24.2 +/- 5.6 to 23.1 +/- 5.5, and left ventricular mass index from 195 +/- 83 to 111 +/- 72 (P = 0.0004). Mean wall thickness index and relative wall thickness showed significant differences between the two groups postoperatively but no significant difference preoperatively. CONCLUSION: Hearts dilated due to chronic mitral incompetence respond differently after valvular replacement with total chordal excision depending on whether a rheumatic or myxomatous mitral valve is involved.  相似文献
