摘要

主动脉瓣置换术后冠状动脉口狭窄是一种罕见但可能致命的并发症。外科医生必须对AVR后出现的急性心肌缺血、心律失常和心力衰竭保持高度警惕。根据大多数报道，这一事件可以根据时间分为两组;早期急性期多发生在CPB脱机术中或ICU住院早期，晚期多出现在术后1 ~ 6个月。在这里，我们描述了一个不寻常的亚急性表现，右冠状动脉口狭窄在SAVR后12天，这是成功地治疗了再跳心脏冠状动脉旁路移植术(CABG)。

Delayed Coronary Ostial Stenosis after Surgical Aortic Valve Replacement and Root Enlargement Treated with Beating Heart On-Pump CABG

Coronary ostial stenosis after surgical aortic valve replacement (SAVR) is a rare but potentially fatal complication. Surgeons must have a high level of vigilance regarding the presentation of acute myocardial ischemia, arrhythmia, and heart failure after AVR. According to most reports, this event can be time-dependent divided into two groups; early acute phase that mostly happens intraoperative during weaning of CPB or in early ICU stay, and late presentation usually appears 1 - 6 months post surgery. Here, we describe an unusual subacute presentation of right coronary ostial stenosis 12 days after SAVR, which was treated successfully with redo beating heart coronary artery bypass grafting (CABG).
