  • Title: Right ventricle-to-aorta conduit in pulmonary atresia with intact ventricular septum and coronary sinusoids.
    Author: Freeman JE, DeLeon SY, Lai S, Fisher EA, Ow EP, Pifarré R.
    Journal: Ann Thorac Surg; 1993 Dec; 56(6):1393-5. PubMed ID: 8267445.
    Abstract:
    A 20-month-old girl with pulmonary atresia, intact ventricular septum, and ventriculocoronary connections underwent successful interposition of a right ventricle-to-aorta conduit and Fontan operation. The patient initially had a modified Blalock-Taussig shunt at birth and subsequently a bidirectional Glenn shunt at 8 months of age. After Fontan and right ventricle-to-aorta conduit placement, the suprasystemic right ventricular pressure dropped to systemic levels without causing myocardial injury. Additionally, the right ventricular cavity enlarged. We believe that the use of a right ventricle-to-aorta conduit should provide a valuable alternative and improve the outlook of certain patients with pulmonary atresia, intact ventricular septum, and ventriculocoronary connections.
