Abstract
Background: Repair of total anomalous pulmonary venous drainage (TAPVD) in neonates remains a challenge as it is often associated with severe obstruction. We describe a large cohort of neonates who underwent TAPVD repair at a single institution.
Methods: From 1973 to 2008, 112 patients underwent simple TAPVD surgery during the first month of life. Data collection occurred retrospectively.
Results: Preoperative pulmonary venous obstruction (PVO) occurred in 89 (79.5%) patients. There were 12 (10.7%) early deaths. Significant risk factors were bypass time greater than 65 minutes (p=0.014) and emergent surgery (p=0.005). Hospital mortality was unchanged throughout the 3 eras (1973 to 1988, 1989 to 1998, 1999 to 2008), despite an increase in patients with preoperative acidosis (p=0.004) and severe TAPVD obstruction (p=0.038) during the recent 10 years. There were 6 (6.25%) late deaths within 2 years of repair. Survival at 20 years was 83.4% (95% confidence interval 75 to 89). Risk factors for late death were operative weight 2.5 kg or less (p=0.004) and postoperative pulmonary hypertensive crisis (p=0.02). Reoperation for recurrent PVO was required in 13 patients (11.9%). Risk factors were operative weight 2.5 kg or less (p=0.035) and postoperative pulmonary hypertensive crisis (p=0.002). Follow-up was 96% complete and survivors (n=90) were asymptomatic at a median age of 11.7 years.
Conclusions: Hospital mortality remained unchanged over the 36-year period. Survival beyond 2 years offers excellent outcome. Risk factors for mortality were the preoperative clinical status, prolonged bypass time, persisting micro-obstruction, and low operative weight. A reduction in mortality will likely require development of effective medical management for patients who have peripheral PVO not amenable to surgical repair.
