Left ventricular aneurysms are a frequent complication of myocardial infarction. Some aneurysms occur secondary to trauma, previous operation, or infection. This report presents the case of a patient with a posterior submitral left ventricular aneurysm, which occurred following mitral valve replacement. The complete obliteration of the pericardial sac due to previous cardiac operation and the posterior location made external dissection of the aneurysmal wall technically impossible. Closure of the defect through the valve orifice by placing a patch over the neck of the aneurysm was found to be a relatively simple and safe technique combined with replacement of the prosthetic valve. The possibility of injury to the circumflex coronary artery was reduced using this surgical approach.
左心室室壁瘤是心肌梗死常见的并发症。有些室壁瘤继发于外伤、既往手术或感染。本报告介绍了一例二尖瓣置换术后发生后下二尖瓣环左心室室壁瘤的患者。由于既往心脏手术导致心包腔完全闭塞以及瘤体位于后方，使得瘤壁的外部剥离在技术上无法实现。通过在瘤颈部放置补片经瓣膜口封闭缺损，被认为是一种相对简单且安全的技术，并同时进行人工瓣膜置换。采用这种手术方法可降低回旋支冠状动脉损伤的可能性。
