A, Freedom from recurrent CHF: MVPPM versus NOMVPPM (P < .0001). B, Cumulative incidence of postoperative PHTN: smaller sized valve (≤27) versus larger (≥29) sized valve (P = .005). C, Adjusted survival according to MVPPM versus NOMVPPM (P = .05). CHF, Congestive heart failure; PHTN, pulmonary hypertension; MVPPM, mitral valve patient–prosthesis mismatch.
