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.
Why the study?
Does continued left ventricular remodeling predict recurrent ischemic mitral regurgitation late after ring annuloplasty?
Observational (n=30)
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.
No takes yet. Share an insight, caveat, or question.
May inform post-annuloplasty LV shape surveillance; leaves open whether remodeling modification prevents recurrent ischemic MR.
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.
