Key result
Recurrent mitral regurgitation at a mean of 47 months after ring annuloplasty is associated with continued left ventricular remodeling, with end-systolic LV sphericity index as the sole predictor.

Does continued left ventricular remodeling predict recurrent ischemic mitral regurgitation late after ring annuloplasty?
Recurrent ischemic mitral regurgitation late after ring annuloplasty is driven by continued left ventricular remodeling, specifically increased end-systolic sphericity.
Hung et al. (2004) conducted an observational in Ischemic mitral regurgitation (n=30). Ring annuloplasty was evaluated on Echocardiographic measures of MR and LV remodeling. Recurrent mitral regurgitation at a mean of 47 months after ring annuloplasty is associated with continued left ventricular remodeling, with end-systolic LV sphericity index as the sole predictor.
