Kindya B, et al. - Researchers investigated the role played by mitral regurgitation (MR) etiology and its severity in outcomes for patients undergoing transcatheter aortic valve replacement (TAVR). Analysis of a baseline and a follow-up (within 30 days of TAVR) echocardiogram in 270 patients undergoing TAVR at two hospitals was conducted. As per findings, they recommend providing special consideration to patients with moderate-severe degenerative MR undergoing TAVR. In view of the continuous evolution of transcatheter approaches for mitral valve repair and replacement, moderate-severe degenerative MR patients may benefit from consideration of double valve intervention.
