Objectives: This study was performed to analyse the surgical results of total anomalous pulmonary venous connection (TAPVC) repair at a single institution and to identify trends and variables associated with mortality and morbidity, particularly predictors of recurrent pulmonary venous obstruction (PVO). Methods: Our surgical database contained 256 patients with biventricular anatomy who underwent surgical repair for TAPVC from 1981 to 2016. The anatomic TAPVC subtypes in this study were as follows: 114 supracardiac (44.5%), 56 cardiac (21.9%), 64 infracardiac (25.0%) and 22 mixed (8.6%) types. The follow-up for the entire study ranged from 1.6 months to 28.2 years (median 10.4 years). Preoperative PVO was present in 128 patients (50.0%). All patients with TAPVC with single-ventricle anatomy were excluded from the analysis. Data were retrospectively reviewed. Results: Seven (2.7%) early deaths and 26 (10.1%) late deaths occurred. The actuarial survival rate at 20 years postoperatively was 85.3%. The preoperative predictors of operative mortality were younger age and the era of TAPVC repair (before 1998). In addition to these variables, associated cardiac anomalies were predictors of late mortality. Those for postoperative PVO were younger age, lower weight and being an emergency case. The actuarial survival rate at 20 years was 38.6% for patients with postoperative PVO and 92.2% for patients without postoperative PVO (P < 0.001). Conclusions: The long-term outcomes after TAPVC repair in patients with biventricular anatomy were satisfactory. Mortality was significantly associated with the rate of progression of postoperative PVO, and careful follow-up was required especially within 6 months after the primary operation.
