Change in mitral regurgitation severity impacts survival after transcatheter aortic valve replacement
Background: The impact of a change in mitral regurgitation (MR) following TAVR is unknown. We studied the impact of baseline MR and early post-procedural change in MR on survival following TAVR. Methods: The SWEDEHEART registry included all TAVRs performed in Sweden. Patients were dichotomized into no/mild and moderate/severe MR groups. Vital status, echocardiographic data at baseline and within 7
