Abstract
The repair of many complex congenital cardiac anomalies is impossible without the use of an extracardiac conduit to establish continuity between the right ventricle and the pulmonary artery. Until now the «ideal» conduit remains a subject of search, and many patients with implanted prosthesis pulmonary artery trunk require reoperations to correct the different complications. The spectrum of complications associated with the implantation of extracardiac conduit includes conduit stenosis, the valve conduit failure, infective endo- carditis of conduit, its thrombosis, pulmonary embolism and other.
The review article is devoted to the surgical treatment of complications developing dysfunction right ventricle – pulmonary artery conduit. The causes of dysfunction of different types of extracardiac conduits, the main indications for repeat surgery and methods of correction extracardiac conduit obstruction are discribed. An assessment of the immediate and long-term results of surgical correction of various techniques of right ventricle – pulmonary artery conduit obstruction and the risk of poor results reoperations are presented in the article.
