| Abstract: | The purpose of this study was to evaluate mitral regurgitation (MR) severity in patients undergoing transcatheter aortic valve replacement (TAVR) by standardized assessment of two-dimensional (2D) transthoracic echocardiography (TTE) and 1-year echocardiographic and clinical outcomes. Pre- and post-procedural TTE’s of patients undergoing TAVR between 2008 and 2014 were analyzed. MR was graded according to current guidelines with a systematic and integrated approach. Longitudinal echocardiographic and clinical results were analyzed. Regression analysis was performed for change in MR grade at follow-up, using pre-determined variables and confounders. Pre- and post-procedural TTE were available in 213 subjects. Significant MR was seen in 22% at baseline and 15% at follow-up; MR grade?≥?3 in
