Abstract

Objectives: To Report the early outcomes of valved conduit for right ventricular outflow tract reconstruction in congeniatl heart defects at National Children’s Hospital in 2020. Methods: In 2020, 1200 cases of open-heart surgery were conducted at our hospital, in which 70 patients (5.8%) are using the valved conduit for reconstruct the right ventricular outflow tract. We conducted a cross-sectional study, describing the early postoperative resultsin this group of patients. Results: There were 44 male (62.9%) and 26 female (37.1%), in which Truncus (15.7%), Pulmonary atresia or stenosis (60%) Ross’s procedure (5.7%),Pulmonary valve replacement (18.6%). The conduits areContegra (91.4%), Hancock (5.7%), Homograft DMP (2.9%) with an average size of 16 (9-25) mm. At the time of surgery, the mean age was 24.4 ± 33.7 [1 - 171] months and the meanweight was 9.2 ± 6.4 [2.6 - 41.0]kg. The mean bypass time and cross-clamped time were 155 ± 51 [72 - 381] minutes and 81 ± 47 [21 - 209] minutes, respectively. Early death has 5 patients (7.1%): 4 patients died during hospital stay, 1 patient died 1 month after dischargedue to pneumonia. The remaining patients are monitored for at least 3 months after surgery. The echocardiography at last check-up showed that the average rate of mild to moderate pulmonary insufficency (15.7%), No PI (84.3%). Mean pressure gradient across the conduitwas10 ± 8 [1 - 35] mmHg. Conclusions: Using a valved conduit to shape the right ventricular outflow tract in complicated congenital heart defect patients at National Children’s Hospital is feasible. Long term follow-up is absolutely in need.
