Pulmonary root translocation for biventricular repair of double-outlet left ventricle

Double-outlet left ventricle is conventionally repaired with an extracardia c conduit when pulmonary stenosis is present. We report the use of pulmonar y root translocation to the right ventricle to construct the posterior wall with autologous tissue and a porcine pericardial monocusp ventricular outf low patch anteriorly for 2 patients with double-outlet left ventricle. This technique allows minimization of pulmonary insufficiency, avoids coronary artery ligation with infundibulotomy, and has a major theoretical advantage for growth potential.
