摘要

经导管主动脉瓣置换术(TAVR)术后晚期冠状动脉闭塞是一种罕见但严重的并发症。我们为您介绍一位 85 岁的女性,她在经导管主动脉瓣置换术后 11 个月出现胸痛,继发于左主冠状动脉阻塞。血管造影显示部分闭塞,需要进行经皮冠状动脉介入治疗。尽管最初由于与 TAVR 瓣膜的相互作用而导致介入困难,但双腔微导管的使用促进了支架的成功植入,从而解决了阻塞问题。该病例强调了 TAVR 术后冠状动脉晚期闭塞诊断和治疗的复杂性,强调了警惕识别和创新介入策略对优化患者预后的重要性。

Challenging coronary access in a patient with delayed coronary obstruction following TAVR, facilitated by the use of a dual lumen microcatheter

Late onset coronary occlusion post-transcatheter aortic valve replacement (TAVR) is a rare yet significant complication. We present an 85-year-old female with chest pain secondary to left main coronary artery obstruction eleven months post-TAVR. Angiography revealed a partial occlusion necessitating percutaneous coronary intervention. Despite initial challenges in engagement due to interaction with the TAVR valve, use of a dual lumen microcatheter facilitated successful stenting, resulting in resolution of the obstruction. This case underscores the diagnostic and therapeutic complexities of late coronary occlusion after TAVR, emphasizing the importance of vigilant recognition and innovative interventional strategies in optimizing patient outcomes.
