Relationship Between Preoperative Diastolic Transpulmonary Gradient With Pulmonary Vascular Resistance and 1-Year and Overall Mortality Rates Among Patients Undergoing Cardiac Transplant.

Objectives: Cardiac transplant is a life-saving procedure for patients with end-stage heart failure. Preoperative pulmonary vascular resistance is indicative of intrinsic pulmonary vascular disease and correlates with posttransplant survival. However, its measurement is costly and time consuming.
