Insights
This study on total anomalous pulmonary venous drainage repair shows a low 2.3% mortality rate. Survivors experienced excellent long-term outcomes without medication, highlighting successful surgical interventions.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Total anomalous pulmonary venous drainage (TAPVD) is a critical congenital heart defect.
- Surgical repair is essential for survival in neonates and infants.
- Understanding outcomes is crucial for improving patient management.
Purpose of the Study:
- To evaluate the surgical outcomes and long-term results of patients with TAPVD.
- To identify risk factors and complications associated with TAPVD repair.
- To assess the efficacy of surgical intervention in different types of TAPVD.
Main Methods:
- Retrospective review of 44 patients undergoing TAPVD repair between 1979 and 1987.
- Classification of TAPVD into supracardiac, cardiac, and infracardiac types.
- Analysis of perioperative data, including obstruction, emergency surgery, and mortality.
- Long-term follow-up to assess survival, reoperation, and medication status.
Main Results:
- Overall hospital mortality was 2.3% (1 death).
- 50% of patients had obstructed venous drainage; 12 required emergency surgery.
- Pulmonary artery pressure exceeded systemic pressure in 17 patients post-repair.
- Two of four reoperated patients died due to pulmonary vein sclerosis.
Conclusions:
- Surgical repair of TAPVD demonstrates a low mortality rate with favorable long-term outcomes.
- Pulmonary vein sclerosis is a significant long-term complication requiring vigilance.
- Prompt surgical intervention is critical for improving survival in TAPVD patients.
Abstract:
Forty-four patients with total anomalous pulmonary venous drainage underwent repair between 1979 and 1987. The anomalous drainage was supracardiac in 16, cardiac in 12, and infracardiac in 16. Median age at repair was 15 days and median weight, 3.3 kg. In 22 patients (50%) the venous drainage was obstructed. Emergency operation was necessary in 12 patients, and the condition of seven additional patients deteriorated while they were awaiting semiurgent operation. There was one hospital death (mortality rate 2.3%), occurring in a 2-week-old premature neonate with infracardiac drainage. In 17 of 44 patients, mean pulmonary artery pressure equaled or exceeded systemic arterial pressure immediately after repair. Four patients have required reoperation and two of these have died as a result of peripheral extension of pulmonary vein sclerosis. In the review period of from 1 month to 7 years, all survivors are well and receiving no medication.
