Right ventricular outflow patch reconstruction for repair of double-outlet left ventricle.

Double-outlet left ventricle (DOLV) is conventionally repaired with an extracardiac conduit when pulmonary stenosis is present. We report a case of surgical repair for DOLV with severe pulmonary stenosis where the right ventricular outflow tract was established using a vascular graft patch anteriorly after constructing the posterior wall with autologous tissue. This approach provides excellent hemodynamic repair without the use of an extracardiac conduit and has the major advantage of growth potential.
