To evaluate the predictors of pulmonary artery systolic pressure (PASP) in organic mitral regurgitation (MR) and its prognostic value after surgery. ⋯ In organic MR, mitral deceleration time, mitral E/E' and left atrial volume correlate with PASP. Pulmonary artery systolic pressure > or = 50 mmHg is an independent predictor of overall and cardiovascular mortality after surgery in organic MR.
