Radical correction of double outlet of right ventricle with conduits

The use of an artificial pulmonary arterial trunk in the radical correction of complicated congenital heart disease (CHD), such as double origin of the great vessels (DOGV) from the right ventricle (RV) concurrent with pulmonary stenosis is the operation of choice in the presence of anomalous origin of coronary arteries. In 1990 to 2000, the Department of Surgical Treatment of CHD in Old Children, A.N. Bakulev Research Center of Cardiovascular Surgery, Russian Academy of Medical Sciences, repaired the RV outflow tract in 10 patients during radical correction by using an extrac-ardiac conduit. The patients' age ranged from 5 to years (mean, 9,2 ± 2,4 years). Two dacron prostheses were implanted, one of them had a xenoaortic valve. Teflon, vitaflon, and Gore-Tex conduits were used in 2,2, and 2 patients, respectively. A xenopericardial two-flap monoleaflet conduit was employed in 2 cases. In most cases, there was a significant RV pressure reduction that averaged 55,2 ± 14,7 mm Hg. If transannular plasty of the RV outflow tract and the pulmonary artery cannot be performed by means of a flap, the use of conduits provides an adequate repair of the RV outflow tract and considerably enhances life quality in patients.
