The presence of left ventricular hypoplasia in double-outlet right
ventricle may increase the risk of biventricular repair and Fontan
procedures. The hypoplastic left ventricle of an 11-year-old girl with
complex double-outlet right ventricle was successfully incorporated in a
modified biventricular repair by Dacron patch closure of the ventricular
septal defect, diversion of venous return of the inferior vena cava to the
mitral valve with an intraatrial baffle, insertion of a left ventricular
apex to pulmonary artery valved aortic homograft, and diversion of residual
systemic venous return directly to the lungs with a bidirectional superior
vena cava to pulmonary artery shunt. Postoperatively, the systemic venous
atrial pressure was 6 mm Hg and the pulmonary artery pressure was 14 mm Hg.
This method is proposed as a partial biventricular repair hemodynamically
superior to the Fontan procedure, although aortic homograft revision may be
required in the future.
