A total of 225 symptomatic patients underwent the complete repair of tetralogy of Fallot. The mortality rate correlated with the preoperative pulmonary artery to aortic diameter ratio, left ventricular end-diastolic volume and postoperative size of the right ventricular outflow tract. The postrepair right ventricular to aortic systolic pressure ratio and right ventricular to pulmonary arterial systolic pressure gradient were regulated by the cross-sectional area index of the pulmonary annulus after enlargement in the patients without a transannular patch. Most patients with a transannular patch kept excellent postoperative hemodynamic results, but when pulmonary regurgitation or pulmonary hypertension was significant, the right ventricular systolic pressure was higher than that of the patients without a transannular patch. Significant pulmonary regurgitation was avoidable as long as CSAI was 2.5 cm^2/m^2 or less and a single cusp was mounted on the patch.
