Coronary Artery Disease and Transcatheter Aortic Valve Replacement

"In patients with coronary artery disease undergoing transcatheter aortic valve replacement (TAVR), the decision of whether to revascularize, which lesions to revascularize, and the optimal timing of revascularization remains controversial. The sequence of revascularization should be made on a case-by-case basis. Pre-TAVR revascularization (staged or simultaneous with TAVR) is preferred due to unobstructed access to coronary ostia and is important to consider especially in cases in which long self-expanding valves are used. In patients who are hemodynamically compromised, the valve should be addressed first, as the most important cause of mortality is heart/multiorgan failure."
