OBJECTIVES Surgical outcomes of supracardiac total anomalous pulmonary venous connection (TAPVC) repair by the posterior technique (PT) remain unsatisfactory. This study aimed to compare the outcomes of the modified L-shaped incision technique with the PT for supracardiac TAPVC repair. METHODS From January 2009 to December 2019, 121 consecutive patients with supracardiac TAPVC undergoing surgical repair in our institution were included (L-group, n = 53; PT group, n = 68). A propensity score-matched analysis was performed. Patients with single-ventricle physiology or atrial isomerism were excluded. All clinical data were retrospectively analysed. RESULTS In the unmatched cohort, the median follow-up duration was 33 months (interquartile range 26–65 months). There were 5 operative mortalities (4.1%) and 12 late mortalities (9.9%). Postoperative pulmonary venous obstruction (PVO) was documented in 21 patients. After matching (52 pairs), the overall survival rate in the L-group was 88.2% at both 3 and 5 years. For the propensity score-matched patients with preoperative PVO (n = 20), statistically significant differences (P = 0.002) were found by Kaplan–Meier curves with freedom from death and postoperative PVO at 1 and 3 years of 100% and 85.7% [standard deviation (SD): 13.2%] in the L-group and 90% (SD: 9.5%) and 22.9% (SD: 14.1%) in the PT group, respectively. Multivariable analysis revealed that the use of the PT was an independent risk factor for death and postoperative PVO (hazard ratio 4.12, 95% confidence interval 1.12–15.16; P = 0.03). CONCLUSIONS The modified L-shaped incision technique provided an acceptable outcome for supracardiac TAPVC repair. Compared with PT, the modified L-shaped incision technique was significantly associated with decreased death and postoperative PVO in patients with obstructed supracardiac TAPVC.

Background Prenatal diagnosis and planned peripartum care is an unexplored concept in China. This study aimed to evaluate the effects of the "prenatal diagnosis and postnatal treatment integrated model" for newborns with critical congenital heart disease. Methods The medical records of neonates (≤ 28 days) admitted to Fuwai Hospital were reviewed retrospectively from January 2019 to December 2020. The patients were divided into "prenatal diagnosis and postnatal treatment integrated group" (n = 47) and "non-integrated group" (n = 69). ResultsThe age of admission to the hospital and the age at surgery were earlier in the integrated group than in the nonintegrated group (5.2 ± 7.2 days vs. 11.8 ± 8.0 days, P < 0.001; 11.9 ± 7.0 days vs. 16.5 ± 7.7 days, P = 0.001, respectively). The weight at surgery also was lower in the integrated group than in the non-integrated group (3.3 ± 0.4 kg vs. 3.6 ± 0.6 kg, P = 0.010). Longer postoperative recovery time was needed in the integrated group, with a median mechanical ventilation time of 97 h (interquartile range 51-259 h) vs. 69 h (29-168 h) (P = 0.030) and with intensive care unit time of 13.0 days (8.0-21.0 days) vs. 9.0 days (4.5-16.0 days) (P = 0.048). No significant difference was observed in the all-cause mortality (2.1 vs. 8.7%, P = 0.238), but it was significantly lower in the integrated group for transposition of the great arteries (0 vs. 18.8%, log rank P = 0.032). Conclusions The prenatal diagnosis and postnatal treatment integrated model could significantly shorten the diagnosis and hospitalization interval of newborns, and surgical intervention could be performed with a lower risk of death, especially for transposition of the great arteries.

these patients and evaluate the effectiveness of the bivalvation technique. Methods Patients The institutional ethics committee approved this study. We reviewed the medical documents of 546 patients who underwent single-ventricle palliative surgeries from January 2007 to April 2018 at Fuwai Hospital, Beijing, China: 6 patients with severe pulmonary stenosis and 38 patients with pulmonary atresia were identified; 15 patients underwent banding and 20 patients underwent Blalock-Taussig shunt were found as stage I palliative surgeries. A total of 54 patients were diagnosed with CAVV, and 37 of them underwent single-ventricle palliative surgery combined with CAAV repair. Patients with a balanced CAVV who
