Sacubitril-Valsartan Reduces Functional Mitral Regurgitation
In patients with chronic heart failure and functional mitral regurgitation, sacubitril/valsartan was associated with greater reduction in mitral regurgitation compared to valsartan alone.

When to Operate on Chronic Aortic Regurgitation Patients
A retrospective observational study of patients with moderate to severe aortic regurgitation followed for five years showed that symptoms or a left ventricular end-systolic dimension index > 20 mm/m2 were multivariate predictors of death.
