Abstract:
Transcatheter aortic valve implantation (TAVI) has become the main treatment for elderly patients with middle and high risk aortic stenosis. However, coronary artery occlusion (CAO) related to TAVI is a very serious complication, which often leads to poor prognosis. Therefore, active preoperative prevention is particularly important. Preoperative computed tomography evaluation, bioprosthetic or native aortic scallop intentional laceration and chimney stent implantation technology can prevent TAVI-related coronary orifice obstruction. Ensuring commissural alignment during operation can reduce the occurrence of coronary occlusion, but its long-term prognosis needs further study. In addition, percutaneous coronary intervention is the main treatment, but there are problems such as difficult coronary access after TAVI. This article summarized the research progress in the mechanism, prevention and treatment of CAO related to TAVI.
