Total anomalous pulmonary venous drainage in infancy
Insights
This study on total anomalous pulmonary venous drainage (TAPVD) correction in infants found a 36% hospital mortality but no late deaths. Improved survival is linked to early diagnosis, aggressive treatment, and comprehensive care.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
- Thoracic Surgery
Background:
- Total anomalous pulmonary venous drainage (TAPVD) is a critical congenital heart defect.
- Surgical correction is essential for infant survival.
- Early surgical intervention outcomes require continuous evaluation.
Purpose of the Study:
- To evaluate the surgical outcomes for infants undergoing correction of TAPVD.
- To identify factors influencing survival rates in TAPVD repair.
- To analyze mortality trends in relation to TAPVD subtypes and management strategies.
Main Methods:
- Retrospective analysis of 39 infants undergoing TAPVD correction between 1971 and 1975.
- Classification of TAPVD by drainage type: supracardiac, intracardiac, infracardiac, and mixed.
- Data collection on patient demographics, operative details, and mortality outcomes.
Main Results:
- Overall hospital mortality was 36% (14 of 39 infants operated on under 1 month of age).
- No late deaths were recorded post-hospital discharge.
- Highest operative mortality observed in patients with direct superior vena cava or infradiaphragmatic drainage, the latter group experiencing pulmonary venous obstruction.
Conclusions:
- Early recognition, prompt referral, and aggressive diagnostic approaches improve TAPVD outcomes.
- Comprehensive surgical correction with attention to anastomosis and left atrial size is crucial.
- Intensive postoperative care, particularly fluid balance and pulmonary complication management, significantly impacts survival.
Abstract:
Between May 1971 and December 1975, 39 infants had operations for correction of total anomalous pulmonary venous drainage. Fourteen of the 39 patients were under 1 month of age at the time of operation. Twenty-four patients had supracardiac, 7 intracardiac, and 6 infracardiac total anomalous pulmonary venous drainage, and 2 had a mixed type. The overall hospital mortality was 36 per cent. There have been no late deaths. The improvement in survival rate in this series is attributed to: (1) earlier recognition and prompt referral, (2) an aggressive approach to diagnosis involving complete cardiac catheterisation and angiocardiography, (3) vigorous preoperative care, (4) early complete correction including construction of a large anastomosis and enlargement of the left atrium when indicated, and (5) intensive postoperative management paying particular attention to fluid balance and treatment of pulmonary complications. Operative mortality was highest in patients with total anomalous pulmonary venous drainage directly to the superior vena cava, and in those with infradiaphragmatic drainage of whom all had pulmonary venous obstruction. Mortality was not closely related to age, body weight, or severity of pulmonary hypertension.
