经导管主动脉瓣置换术后冠状动脉的进展是一个重要问题。这些患者的冠状动脉血运重建可能具有挑战性，因为人工瓣膜结构在进入冠状动脉口时可能存在障碍。对于代表冠状动脉病变最复杂子集的慢性完全闭塞（CTO）来说，这变得更加困难。我们报告了首例冠状动脉 CTO 血运重建患者，该患者几个月前接受了 TAVR，并讨论了干预此类病变的复杂性。
Progression of coronary arteries after transcatheter aortic valve replacement is an important issue. Coronary revascularization in these patients can be challenging because of potential hindrance posed by the artificial valve structure in getting access to the coronary ostium. This gets even more difficult in chronic total occlusions (CTOs) that represent the most complex subset of coronary lesions. We report the first case of coronary CTO revascularization in a patient who underwent TAVR a few months prior and discuss the complexities involved in intervening such lesions.
