As the indications for transcatheter aortic valve replacement (TAVR) expand to low-risk young patients, the number of patients undergoing percutaneous coronary intervention (PCI) after one or more TAVR may increase. The coronary access for PCI after TAVR has become a very practical and severe problem. Coronary re-intervention poses technical difficulties, and compared to balloon expandable valve, the use of self-expanding valve is more challenging for the coronary access for PCI after TAVR. This article discusses the selection of appropriate valves before TAVR, the implementation of intraoperative commissural alignment technology, and the techniques for mastering the coronary access for PCI after TAVR, in order to improve the success rate of the coronary access for PCI after TAVR.
