Abstract

Ischaemic heart disease and aortic stenosis are potentially life-threatening conditions. A post-infarct left ventricular aneurysm, when combined with the above, is particularly hazardous. We present a case where all three conditions occurred simultaneously and describe the surgical approach undertaken to attempt correction. The patient underwent aneurysmectomy together with aortic valve replacement and two-vessel coronary artery bypass grafting. The aneurysm was excised with direct linear closure of the walls using a Teflon-buttressed interrupted mattress suture technique. Post-operatively, ventricular systolic function was good (LVEF 40%) together with a well-seated aortic valve showing no paravalvular leaks. This case highlights the importance of meticulous removal of thrombus from the aneurysm and everting the edges thereby eliminating a thrombogenic surface and the risk of embolic stroke. The restorative procedure itself serves to underline the importance of ventricular shape in the effective functioning of the myocardium for sustaining an adequate stroke volume with normalized physiology.

摘要

缺血性心脏病和主动脉瓣狭窄是潜在的危及生命的病症。心肌梗死后左心室室壁瘤若与上述病症同时存在,则尤其危险。我们呈现了一个三种病症同时发生的病例,并描述了为尝试矫正而采取的手术方法。该患者接受了室壁瘤切除术,同时进行了主动脉瓣置换和双支冠状动脉搭桥术。使用带特氟龙支撑的间断褥式缝合技术,通过直接线性缝合壁层来切除室壁瘤。术后,心室收缩功能良好(左心室射血分数40%),且主动脉瓣固定良好,无瓣周漏。该病例突出了从室壁瘤中细致清除血栓以及将边缘外翻从而消除血栓形成表面和栓塞性中风风险的重要性。修复手术本身强调了心室形状对于心肌有效运作以维持正常生理状态下足够的每搏输出量的重要性。
