Anomalous left circumflex artery obstruction after transcatheter aortic valve-in-valve placement
摘要
Coronary obstruction (CO) after transcatheter aortic valve replacement (TAVR) valve-in-valve (VIV) is a rare, albeit severe, complication. Pre-procedural planning with Cardiac CT Angiography (CCTA) is crucial for identifying risk factors. However, the incidence of CO after TAVR over the past decade remains 0.8%1.
