Two patients with a rare form of double-chambered, double-outlet right
ventricle (DORV) are described. Both patients had associated pulmonary
stenosis, ventricular septal defect, and a large tricuspid valve whose
chordal attachments crossed the right ventricular outflow tract. The
angiocardiographic, echocardiographic, and operative findings were
distinctive. The right ventricle was positioned as a "cap" sitting atop the
ventricular septal defect at the cephalad end of the left ventricle. The
right ventricle, with its two "horns," was likened to a rider straddling a
saddle. Tricuspid chordal attachments extended into each of the two right
ventricular "horn." No repair was performed in the asymptomatic patient.
The other repair involved closure of the tricuspid orifice and insertion of
a valved extracardiac conduit from the right atrium to the pulmonary
artery.
