Preoperative N-terminal pro-B type natriuretic peptide level can predict the regression of left ventricular mass after valvular surgery in patients with chronic severe mitral regurgitation: One-year follow-up

A lower preoperative NT-proBNP level predicted the regression of LV mass after valvular surgery in patients with chronic severe MR. This measure could be used as a biomarker for predicting the postoperative course in such patients.
