Phenotype-specific mitral regurgitation trajectories following transcatheter aortic valve replacement in low-flow aortic stenosis.
OBJECTIVES Mitral regurgitation (MR) evolution after transcatheter aortic valve replacement (TAVR) in low-flow aortic stenosis (LFAS) is poorly characterized. The authors evaluated MR trajectories across LFAS phenotypes, predictors of MR worsening, and associations with clinical outcomes. METHODS The authors retrospe...
