The objective of the present work is to describe the experience with intravenous (IV) sildenafil in heart transplant (HT) patients with reactive pulmonary hypertension (PH) who developed right ventricular dysfunction (RVD) in the immediate postoperative period. The first 5 patients who received IV sildenafil followinga HT are presented. The HTs took place(More)
