title: [Long-term follow-up studies in 211 patients with tetralogy of Fallot after corrective surgery over 10 years].
abstract: A total number of 427 patients with tetralogy of Fallot who underwent corrective surgery between 1960 and March 1990, in whom 211 patients who survived the surgery over 10 years were evaluated for the follow-up studies. Hemodynamic and cardiac function studies were carried out in 101 patients at the mean interval of 15.7 years (ranges 2 to 21 years). Three methods indicated that patients with muscle resection and pulmonary valvulotomy without patch enlargement (NP) had worse results than the groups with RV patch below valve (RP) and with transannular patch (TP). Also, Holter ECG revealed ventricular arrhythmias in patients with NP were more common than the groups with RP and TP. Sixteen patients (13 with NP, 2 with TP and one with RP) were required reoperation for residual ventricular shunt in 13, residual pulmonary stenosis in 11 and tricuspid regurgitation in 2. All of these 16 patients survived operation and obtained excellent clinical status. It is concluded that patients with TOF after corrective surgery should be carefully followed with short term interval to prevent sudden death and postoperative complications.
