Iatrogenic coronary injury after mitral repair is related to blind annuloplasty suture ligation or kinking of the circumflex artery (CxA) and can present with early ST segment changes, malignant ventricular arrhythmias, and segmental wall motion abnormalities. Corrective treatment is imperative to avoid myocardial infarction and can include removal of the annuloplasty ring or CxA bypass. We present a novel hybrid approach for the rapid diagnosis and management of iatrogenic CxA injury after mitral repair.
二尖瓣修复术后医源性冠状动脉损伤与盲目瓣环成形缝线结扎或回旋支（CxA）扭结有关，可表现为早期 ST 段改变、恶性室性心律失常和节段性壁运动异常。为避免心肌梗死，必须进行纠正治疗，包括去除瓣环成形环或 CxA 旁路。我们提出了一种新的混合方法，用于快速诊断和处理二尖瓣修复术后医源性 CxA 损伤。
