Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is a rare but potentially lethal complication. Main mechanisms are sinus insufficiency or sinus sequestration with well-described risk factors. We present two cases of acute right coronary artery occlusion during TAVI with a self-expanding valve in the absence of classical risk factors and propose a novel mechanism.
经导管主动脉瓣植入术（TAVI）期间的急性冠状动脉闭塞是一种罕见但可能致命的并发症。主要机制是窦部功能不全或窦部隔离，并伴有已明确描述的危险因素。我们报告两例在TAVI期间使用自膨胀瓣膜时发生急性右冠状动脉闭塞的病例，且不存在经典危险因素，并提出一种新机制。
