Summary
We recently treated 7 patients with tricuspid atresia type Ib, and one patient with
type IIIb by enlargement of the ventricular septum defect (VSD), combined with pulmonary
valvotomy or infundibular resection in 3 cases. The result was good or excellent in
the 7 cases with type Ib, while the patient with type Illb, suffering from associated
cardiovascular malformations and operated upon in a very poor hemodynamic state, died
during operation. The procedure is simple and represents no particular risks if one
avoids excessive enlargement of the VSD and does not resect in the area of the cardiac
conduction system. Review of the literature leads us to believe that this operation
should have a place among the different forms of surgical treatment for tricuspid
atresia.
