Objective To summarize clinical outcomes of right ventricle-to-pulmonary artery shunt （Sano shunt）as the first stage palliative operation for patients with pulmonary atresia with ventricular septal defect （PA/VSD）. Methods Between September 2009 and May 2011，17 PA/VSD patients underwent Sano shunt in Fu Wai Hospital. There were 10 male patients and 7 female patients with their median age of 9.7 （2.5-73.8） months and average weight of （8.3±3.4）kg. Preoperative McGoon ratio was 1.04±0.29 and Nakata index was （102.0±56.9） mm2/m2. Five children had severe intrapericardial left pulmonary aretery stenosis，11 patients had patent ductus arteriosus （PDA），and 1 patient had major aorto-pulmonary collateral arteries. Preoperative transcutaneous oxygen saturation （SpO2） was 72.6%±11.6%. Results All the patients received Sano shunt placement successfully. Eleven patients underwent concomitant PDA ligation，and 7 patients underwent concomitant left pulmonary artery plasty. The Sano shunts were constructed with glutaraldehyde-fixed autologous pericardium in 10 patients，fresh autologous pericardium in 1 patient and Gore-Tex graft in 6 patients. All the patients underwent reconstruction of the right ventricular outflow tract via the right ventricular incision. The average cardiopulmonary bypass time was （75.0±30.0） min. Postoperative SpO2 was 89.8%±5.3% and significantly higher than preoperative SpO2 （P＜0.05）. All the patients were discharged alive and followed up for （12.1±6.7） months. During follow-up，8 patients underwent angiography study whose McGoon ratio and Nakata index improved to 2.05±0.37 and （304.8±51.3） mm2/m2 respectively，both of which were significantly higher than preoperative values（P＜0.05）. Four patients successful underwent second stage total correction. Conclusion Sano shunt is a comparatively safe procedure as the first stage palliative operation for PA/VSD patients，and can significant improve their pulmonary artery growth.
Objective To compare the clinical characteristics and prognosis of patients who received two different intraventricular repair. Methods We retrospectively analyzed the clinical data of 24 complete transposition of the great arteries (TGA)/left ventricular outflow tract obstruction (LVOTO) patients who all received intraventricular repair. The patients were allocated into two groups including a REV group and a Rastelli group. There were 13 patients with 9 males and 4 females at median age of 25.2 (6, 72) months in the REV group. There were 11 patients with 10 males and 1 female at median age of 47.9 (14, 144) months in the Rastelli group. Results The age at operation (P=0.041), pulmonary valve Z value (P=0.002), and LVOT gradient (P=0.004), rate of multiphase operation between the REV group and the Rastelli group was statistically different. The mean follow-up time was 17.3 months. And during the follow-up, 1 patient had early mortality, 2 patients had early reintervention, 7 patients had postoperative RVOTO, and received Rastelli and larger VSD inner diameter were associated with postoperative RVOTO. Conclusion As the traditional surgery for TGA/LVOTO patients, the intraventricular repair has a low early mortality and low early reintervention. Modified REV is associated with postoperative peripheral pulmonary vein isolation (PVIS). Patients who received Rastelli operation and with larger VSD inner diameter are more likely to have postoperative RVOTO, but the reintervention for PVI and RVOTO during follow up is very low.
ObjectiveTo summarize our experience of critical congenital heart diseases treatment system for the newborn and to report its surgical results.MethodsWe reviewed the clinical data of 97 neonates with congenital heart diseases who admitted to pediatric cardiac center from January 2019 to August 2020 in our hospital. The patients were divided into a prenatal and postnatal diagnosis and treatment integration group (integrated group, n=41), and a postnatal diagnosis and rapid admission by green channel group (non-integrated group, n=56).ResultsThe age of admission in the integrated group was younger than that in the non-integrated group (3.0 d vs. 11.0 d, P<0.001), and the weight was lighter (3.3±0.4 kg vs. 3.6±0.6 kg, P=0.006), operation age was younger (13.0 d vs. 17.5 d, P=0.004), proportion of palliative surgery was smaller (2.4% vs. 8.9%, P=0.396), time for ventilator assistance was longer (153.0 h vs. 65.0 h, P=0.020), hospital mortality was lower (0.0% vs. 7.1%, P=0.135). There was no significant difference in the follow-up (11.0 months vs. 12 months, P=1.000), out-of-hospital mortality (2.4% vs. 1.8%, P=1.000) and total mortality (2.4% vs. 8.9%, P=0.396) between the two groups.ConclusionPrenatal and postnatal diagnosis and treatment integration can significantly shorten the diagnosis and the hospitalization interval of newborn, that surgical intervention could be performed timely. It can reduce the risk of death before surgery but need longer time for recovery after surgery. Patients with postnatal diagnosis and admitted hospital through green channel also can get perfect results if surgical intervention is performed timely.
