Background. The surgical approach to tetralogy of Fallot (TOF) continues to evolve and now many centers favor early repair for TOF. Methods. Our experience includes 82 consecutive patients less than 1 year old with TOF (n = 74) and TOF with pulmonary atresia (n = 8) who were operated on between January 1992 and March 1998. Mean age at repair was 5.2 ± 1.2 months and mean weight was 4.5 ± 0.4 kg. Seven patients (anomalous left anterior descending artery [n = 1], pulmonary atresia with hypoplastic pulmonary arteries [n = 6]), underwent palliative procedures in the neonatal period followed by complete repair. Forty-nine patients (59%) were symptomatic (severe cyanosis or hypoxic spells), and 33 patients (41%) were asymptomatic. A combined transatrial-transpulmonary approach was employed in 28 patients (34%), and transannular patch or conduit for reconstruction of the right ventricular outflow tract (RVOT) was required in 54 patients (66%). The mean Nakata index was 160 ± 25 mm2/m2. Results. There were no hospital deaths. Mean post-repair peak right ventricular/systemic pressure ratio was 0.48 ± 0.1. There were no late deaths or reoperations during a mean follow-up of 23 ± 5 months. All patients are currently asymptomatic and in New York Heart Association class 1. Postoperative evaluation by two-dimensional and Doppler echocardiography or cardiac catheterization showed minimal pulmonary artery stenosis with a mean pressure gradient of 15 ± 6 mm Hg across the RVOT. Conclusions. Our experience suggests that early repair of TOF can yield excellent results and initial palliation does not preclude early complete repair.
