摘要

一位44岁的男士提出了严重的缺血性心肌病和二尖瓣反流后下壁心肌梗死。超声心动图和磁共振成像显示左心室扩张,伴有大左心室动脉瘤(9.3 × 9.5 cm)和相关血栓。严重的二尖瓣返流由于小叶栓系和左心室射血分数(LVEF) 25%也被看到。患者接受了成功的动脉瘤切除术,并进行了膜片修复和乳头肌逼近。首次体外循环脱机后,术后6天需要临时静脉-动脉体外膜氧合支持。患者术后第16天出院,心功能改善(LVEF为45%),二尖瓣返流痕迹残留,突出了几何修复在解决此类二尖瓣返流方面的有效性,避免了对二尖瓣本身的常规干预。

Repairing the mitral valve without touching the mitral valve-a novel technique.

A 44-year-old gentleman presented with severe ischemic cardiomyopathy and mitral regurgitation post-inferior myocardial infarction. Echocardiography and magnetic resonance imaging revealed a dilated left ventricle with a large left ventricular aneurysm (9.3 × 9.5 cm) and associated thrombus. Severe mitral regurgitation due to leaflet tethering and a left ventricular ejection fraction (LVEF) of 25% were also seen. The patient underwent successful aneurysmectomy with patch repair and papillary muscle approximation. Following initial weaning from cardiopulmonary bypass, 6 days of postoperative temporary veno-arterial extracorporeal membrane oxygenation support were required. The patient was subsequently discharged on postoperative day sixteen with improved cardiac function (LVEF of 45%) and trace residual mitral regurgitation, highlighting the efficacy of geometric restoration in addressing such mitral regurgitation, avoiding conventional intervention on the mitral valve itself.
