Abstract

Outcome of adult patients with repaired tetralogy of Fallot (TOF) was studied with emphasis on postrepair problems. A retrospective review of clinical, echocardiographic, catheterization, and surgical data was performed for 48 patients who underwent corrective repair of TOF after 15 years of age. All patients survived total repair and have been followed up from 3 months to 11 years (median 4.6 years). Postoperatively, 81.3% of patients were in functional class I and 85.4% had normal right ventricular function. One patient (2.1%) died during follow-up. There were 6 reoperations (12.5%) in 5 patients. The indications for reoperation included residual ventricular septal defect (VSD) (n=1), right ventricular outflow obstruction with VSD (n=4), and pulmonary regurgitation (n=1). The 10-year actuarial survival rate was 97.1%, and the 10-year freedom from reoperation was 81.3%. Aortic regurgitation was seen preoperatively in 6 patients (12.5%) and there were 2 newly developed aortic regurgitations after operation, one of which was caused by infective endocarditis. Corrective repair of TOF can be recommended in this patient group since the survival rate, postrepair functional status and hemodynamics are acceptable. Continued close follow-up, however, is essential for early identification and correction of post-repair problems.
