Experience of surgical correction of failures, concomitant with corrected transposition of main vessels (CTMV) in 29 patients was summarized. For pulmonary artery (PA) stenosis demolition in 10 patients the conduits of various design were applied, for moderate left atrioventricular valve (LAVV) insufficiency--its prosthetics. Surgical treatment mortality was 20.7%. Late follow-up results of the operation was studied up in 16 (66.7%) patients. Mean period of observation constituted 3.3 years. Good result was noted in 7 patients, fair--in 9. Lowering of contractile ability of "arterial" ventriculus and the LAVV insufficiency progress were the causes of follow-up results changing for worse. Application of conventional methods of treatment do not put away the basic disorder--CTMV.
