    Abstract:
    OBJECTIVE: The efficacy of using a sutureless approach in order to surgically manage postoperative pulmonary vein stenosis following total anomalous pulmonary venous drainage (TAPVD) has been reported, though outcomes of primary treatment of supracardiac TAPVD remain unclear. We retrospectively reviewed our cardiac center experience, and compared the differences in mid-term outcomes for those patients that received conventional surgery and those that underwent sutureless technique for the primary repair of supracardiac TAPVD. METHODS: A total of 43 patients (median age, 199 days; range, 35 days to 1572 days) with supracardiac TAPVD underwent surgical treatment at our cardiac center from 2014 to 2018 were studied retrospectively. Primary sutureless repair was conducted in 20 cases (46.5%). The pulmonary vein scores, left ventricular ejection fraction (LVEF), baseline of the included patients, postoperative, and outcomes data were analyzed between the two groups. RESULTS: The pulmonary vein scores, indicating the stenosis degree, of two groups were 0.1 ± 0.3 and 0.1 ± 0.3, left ventricular ejection fraction (LVEF) (%) were separately 66.2 ± 12.1 and 67.1 ± 13.6. The average cardiopulmonary bypass time of sutureless techniques group was much longer than conventional group (96.2 ± 32.6 min vs 75.6 ± 28.2 min, P < 0.05), but there was no difference in aortic cross-clamp time between the two groups. Followed up from 0.1 to 4 years, 3 cases died overall, with 1 (5.0%) individual dying from postoperative pulmonary venous obstruction (PVO) in sutureless group, and 2 (8.6%) dying in the conventional group respectively for postoperative infection and post-PVO. There were no differences in the length of stay in the ICU, grades of PVS after surgery, LVEF and reoperation rate between the two groups. CONCLUSIONS: The mortality, post-PVO, follow up results of supracadiac TAPVD showed no differences between sutureless and conventional techniques. Post-PVO supposed to be the main reason for postoperative mortality.
