Abstract

Abstract : Transcatheter aortic valve replacement (TAVR) is becoming the standard of care in the management of severe aortic stenosis for patients in all risk stratifications. Many causes have been identified for acute drop in blood pressure during TAVR. Mitral regurgitation (MR) is a rare, but important acute intraprocedural complication that requires rapid assessment and treatment. Two important reasons for acute MR during TAVR include entanglement of the guide wire in papillary muscles and extension of the guidewire into the left atrium. Here, we report a case of acute reversible MR which was assessed using an echocardiogram and rapidly reversed by removing the stiff preshaped Safari 2 wire from the left ventricle post valve deployment.
