title: Right heart reconstruction following repair of tetralogy of fallot.
abstract: Ten patients in whom tetralogy of Fallot had been repaired underwent late reconstruction of the outflow tract of the right ventricle because of poor hemodynamic results. The major hemodynamic problems that necessitated right ventricular (RV) outflow tract reconstruction were severe pulmonary insufficiency in 9 patients and pulmonary stenosis in 1. Impaired RV contractility and RV aneurysm were the most important factors prompting valve replacement for severe pulmonary insufficiency. Seven patients received a Hancock prosthesis and 3, an aortic homograft. Among the 7 patients who underwent postoperative cardiac catheterization, the surgical results were hemodynamically excellent in 2, good in 3, and unsatisfactory in 2. The management of pulmonary insufficiency in such patients is discussed.
