Abstract
Objectives: Prior studies have reported a high mortality and incidence of post-repair pulmonary venous obstruction (PVO) in mixed total anomalous pulmonary venous connection (TAPVC). This study sought to review the surgical outcomes in this entity.
Methods: A review of 61 patients undergoing surgical repair of mixed TAPVC was conducted. Patients with a single ventricle were excluded. Patients were subdivided into 3 groups according to Chowdhury’s classification. Predictors for death and postoperative PVO were explored by Cox regression model.
Results: This study trended towards an older cohort with a median age of 88 days (interquartile range, 56.5-177). Twelve patients belonged to ‘2 + 2’ type, 40 belonged to ‘3 + 1’ type and the remaining 9 belonged to bizarre type. There were no early death and 7 late deaths. Follow-up was available in 96.7% of the patients after discharge with a median duration of 53 months (range, 1-177). Nineteen patients developed post-repair PVO among whom 2 required reintervention. Patients with preoperative PVO had a 4-fold higher risk (95% confidence interval, 1.36-12.38) of postoperative PVO than those without and were more likely to die (P = 0.009). No statistical difference was observed among the 3 subgroups in terms of mortality (P = 0.058) and postoperative PVO (P = 0.186).
Conclusions: Preoperative PVO was significantly associated with postoperative PVO. There was no statistical difference in terms of death and postoperative PVO among the 3 subtypes of mixed TAPVC. Mid-term results favoured a complete rechanneling of pulmonary veins in ‘3 + 1’ type.
