Outcomes of Surgical Repair of Total Anomalous Pulmonary Venous Drainage: Role of Primary Sutureless Technique

To evaluate the surgical outcomes of total anomalous pulmonary venous drainage focusing on survival, postoperative and pulmonary venous obstruction. Further investigate the role of primary sutureless technique in patients with preoperative pulmonary venous obstruction. Consecutive patients underwent total anomalous pulmonary venous drainage repair in our institution during Jan 2000 to Dec 2019 were enrolled into this retrospective analysis. Since 2016, sutureless repair was regularly applied in patients with preoperative pulmonary venous obstruction. All patients with preoperative pulmonary venous obstruction referred before 2016 had underwent traditional repair. A total of 95 patients were included. During follow-up time of 85 months, main endpoints were documented in 21 patients, including 9 (9.5%) early deaths, 3 (2.3%) late deaths and 9 (9.5%) postoperative pulmonary venous obstructions. Preoperative pulmonary venous obstruction was presented in 26 (27.4%) patients with more emergent surgery (14/26 vs 3/69, P < 0.001) was required. Main endpoints occurred more in patients with preoperative pulmonary venous obstruction (4/26 vs 5/69, P = 0.004). Patients experienced sutureless technique had a lower incidence of postoperative PVO at follow-up (0/11 versus 4/11, P = 0.045). Outcomes of surgical repair for total anomalous venous drainage are satisfactory. However, preoperative pulmonary venous obstruction may be accompanying unfavorable early deaths and postoperative pulmonary venous obstruction. Propensity matching analysis showed that sutureless technique was benefit for postoperative pulmonary venous obstruction without longer cardiopulmonary bypass and aortic cross-clamp time.
