    AbstractAcute coronary obstruction is a relatively rare complication of transcatheter aortic valve replacement (TAVR). Left coronary ostial obstruction is much more common compared to right coronary occlusion due to its relatively lower ostial height from the aortic annulus. We present a case of acute ostial right coronary occlusion immediately upon deployment of a 29-mm Sapien 3 transcatheter aortic valve. The acute right coronary ostial occlusion manifested with ventricular fibrillation, acute right ventricular failure, and right-sided cardiogenic shock. The patient, after undergoing an initial unsuccessful attempt at percutaneous revascularization, was placed on veno-arterial extracorporeal membrane oxygenation (VA-ECMO). This was later transitioned to percutaneous right atrial to pulmonary artery right ventricular support, which led to subsequent recovery.Copyright © 2020, Joshi et al.
