Valvuloplasty for common atrioventricular valve regurgitation in cyanotic heart diseases.

Valvuloplasty for common atrioventricular valvular regurgitation and bidirectional cavopulmonary shunt were successfully performed in 3 children with univentricular heart and double-outlet right ventricle. The free margins of opposite leaflets of the common atrioventricular valve were sutured together to restore coaptation of the leaflets, and Kay-Reed's or DeVega's annuloplasty was carried out. Postoperative examinations revealed significant reduction of atrioventricular valve regurgitation and improvement of general condition in all patients.
