Abstract
Objective: To evaluate the feasibility and reliability of Getex artificial pulmonary valve for reconstruction of right ventricular outflow tract by some new surgical techniques. Methods: A retrospective analysis of the effect of Getex artificial pulmonary valve and those new techniques on early outcomes of reconstruction of the right ventricular outflow tract was made in children from February 2012 to December 2016 in our hospital. Results: A total of 35 patients with complex congenital heart disease were treated with Getex artificial pulmonary artery valve and those new surgical techniques to reconstruct the right ventricular outflow tract in our hospital. The average age were 10 years old, and the average weight was 6-96 (25 ± 22) kg, of which 19 were man, 16 were women, and 5 were reoperated. Related surgical procedures include artificial single flap (21 cases), artificial double valve (6 cases) and comprehensive forming techniques (8 cases). The average extracorporeal circulation time was 75-251 (120 ± 37) minutes, and the average aortic occlusion time was 32-185 (72 ± 28) minutes. The time of postoperative ventilation was 6-68 (24 ± 18) hours, and the duration of the intensive care unit was 14-225 (59 ± 51) hours.There were 2 cases with mild pulmonary stenosis, 5 cases with moderate pulmonary valve regurgitation after operation, and 3 cases were delayed to close the chest. All follow-up patients survived, and the average follow-up time was 15 (6-52) months. Conclusions: Reconstruction of right ventricular outflow tract with Getex artificial pulmonary valve and those new surgical techniques can significantly reduce the right ventricular volume load in the early stage, which is simple, cheap and safe.
