[Pulmonary hypertension in adult patients with secundum atrial septal defect before surgery and in long-term follow-up]. / Nadcisnienie plucne u doroslych pacjentów z ubytkiem przegrody miedzyprzedsionkowej typu II przed operacja i w obserwacjach odleglych.

The aim of the study was to determine pre- and postoperative systolic pulmonary pressure in adult patients with ASD II. The study group consisted of 224 pts who had undergone surgical repair of ASD II in between 1987-1993. The mean postoperative follow-up was 7.5 y. The group (160 F, 66 M aged 17-66 years) was divided on 3 subgroups: age under 20 y--27 pts; 20-40 y--131 pts; and older then 40 y--66 pts. We analysed pre- and postoperative parameters: pulmonary hypertension (PASP-Doppler) and functional class (NYHA). Preoperative pulmonary pressure was 35-50 mm Hg in 69 pts (30.8%) of the group, and over 50 mm Hg in 29 (12.9%). In long-term follow-up of 98 (43.8%) operated patients with coexisting pulmonary hypertension, significant reduction of pulmonary pressure was observed in all patients, even in patients over 40 y. Functional class of heart failure NYXHA improved as well in all patients.
