How TAVI affects CAG and PCI

Transcatheter aortic valve implantation (TAVI) was first introduced in 2002 by Cribier as an alternative to inoperable patients with severe aortic stenosis (AS). Now, after two decades of advancements in device design and operational techniques, the use of TAVI has become widespread as its use was expanded to a wider range of patients. Still, there are challenges with the use of TAVI. One such difficulty is coronary artery cannulation after TAVI.
