Outcomes of Repeat Mitral Valve Surgery in Patients with Pulmonary Hypertension

Abstract

Patients with pulmonary hypertension that undergo redo mitral valve surgery have a 55.9% 5-year survival rate. Increasing age, chronic renal insufficiency, peripheral vascular disease, and preexisting mitral valve prosthesis are associated with early mortality. The severity of pulmonary hypertension does not affect operative mortality rates, but it may decrease 1-, 3-, and 5-year survival.
