Abstract
Introduction. Right ventricle outflow tract (RVOT) reconstruction is not only part of the right heart defects, and aortic valve disease particularly in autologous pulmonary valve (Ross operation). Until recently, the gold standard for RVOT reconstruction in step Ross considered the use aortic and pulmonary allografts. At the present stage of development of surgery of congenital aortic valve prosthesis for the purpose of the pulmonary artery trunk used recently appeared in the arsenal of cardiac surgeons from the bovine jugular vein conduits (BJV).
Material and methods. The article presents the personal experience of implantation of conduits 9 BJV conduits for RVOT reconstruction. The average period of follow-up is 18 [12, 47] months. The median age of the patients – 24 [10; 68] months, the average weight – 14 [9; 29] kg, Z-score – 1,45 [0, 1.93]. Valve insufficiency, stenosis and combined defect were in 1, 3 and 5 patients, respectively. The average systolic pressure gradient between the right ventricle and the pulmonary artery was 6±2 and 9±4 mmHg before and after operation, respectively.
Results. The survival rate was 100%. Two patients had a dysfunction of the conduit due to the development of stenosis of the distal anastomosis, which subsequently transluminal balloon angioplasty estuarine stenosis was performed. Cases containing conduit dysfunction due to valvular insufficiency were detected. Conduit insufficiency cases were not found.
