Clinical Experiences in Surgical Treatment of Heart Valve Disease with Pulmonary Hypertension

Statistical differences in mortality and incidence of perioperative complications between the cases with pulmonary hypertension （pH, group 1） and normal pulmonary pressure （group 2） are reported. The analysis shows: 1. pH in valvular diseases is not a contraindication or operation. 2. Severe pH influences on the perioperative hemodynamics, including low cardiac output and/or chronic heart failure. 3. Relation between pH and postoperative pulmonary complications is of no statistic significance.
