Influence of preoperative transpulmonary gradient on late mortalityh after orthotopic heart transplantation

We reviewed the transpulmonary gradient, pulmonary arterial systolic pressure, pulmonary vascular resistance (Wood units), and pulmonary vascular resistance index (Wood units × Body surface area), recorded preoperatively in 109 recipients aged 44.6 ± 13.5 (mean ± SD) years who underwent orthotopic heart transplantation between March 1984 and March 1988, to identify which measure of pulmonary hypertension most accurately predicts poor outcome after orthotopic heart transplantation
