[The fate of the pulmonary hypertension after ASD-closure in adults (author's transl)].
10 female and 7 male patients, who were operated for secundum type Atrial Septal Defect with Pulmonary Hypertension, got postoperative check-ups including right heart catheterisations. The investigations were performed on the average 6.6 years postoperatively. There was a fall of the systolic pulmonary pressure and of the flow; pulmonary resistance fell in 8 cases and rose in 9. The low left ventricular cardiac index together with an elevated left atrial pressure may be the pathogenetic cause of postoperatively elevated pulmonary resistance.
