Abstract: Objective To evaluate possibility and reliability of the technique of artificial pulmonary valve reconstruction in right ventricular outflow tract reconstruction. Methods We retrospectively analyzed the clinical data of 35 patients with artificial pulmonary valve reconstruction of right ventricular outflow tract reconstruction surgery in our hospital between February 2012 and December 2016. There were 35 patients with 19 males and 16 females at age of 10 years ranged 5 months to 42 years and body weight of 26 (8–62) kg. There were 21 patients with artificial moncusp valve, 6 patients with bicuspid technology, 8 patients with comprehensive forming method. Results Average extracorporeal circulation time was 75–251 (120±37) min. Aorta blocking time was 32–185 (72±28) min. ICU stay time was 14–225 (59±51) hours. Breathing machine auxiliary time was 6–68 (24±18) hours. There were 3 early postoperative deaths. There was no death during the long term following-up time. Thirty-two patients survived with heart function of class Ⅰ in 20 patients, class Ⅱ in 10 patients, class Ⅲ in 2 patients. Conclusion In right ventricular outflow tract reconstruction using the technique of artificial pulmonary valve reconstruction in the operation, it can reduce early postoperative right ventricular volume load. To smooth out perioperative patients, the surgical technique is simple, cheap, safe, but long-term follow-up still needs further observation.
