The surgical treatment of total anomalous pulmonary venous connection
Insights
Complete repair of total anomalous pulmonary venous connection showed high early mortality, especially in infants. However, outcomes improved significantly for older infants and with advancements in surgical care.
Area of Science:
- Cardiology
- Pediatric Surgery
- Congenital Heart Disease
Background:
- Total anomalous pulmonary venous connection (TAPVC) is a severe congenital heart defect.
- Surgical repair is complex and historically associated with high mortality rates.
- Early diagnosis and intervention are critical for improving outcomes in TAPVC patients.
Purpose of the Study:
- To evaluate the outcomes of surgical repair for total anomalous pulmonary venous connection (TAPVC).
- To identify factors influencing early and late mortality in TAPVC patients.
- To assess the impact of surgical timing and technique on patient survival.
Main Methods:
- Retrospective analysis of 35 patients undergoing complete repair of TAPVC between 1968 and 1974.
- Data collection included patient age at operation, hospital mortality, causes of death, and reoperations.
- Comparison of outcomes based on age at surgery and time period.
Main Results:
- Overall hospital mortality was 43%, with a significantly higher rate (86%) in infants under one month.
- No deaths occurred in patients over six months of age.
- Inadequate cardiac performance was the primary cause of death in recent cases (since 1971).
- Early postoperative bleeding required reoperation in 13% of survivors.
- No tracheostomies were needed since 1971, and late reoperations were required in 3 of 20 long-term survivors.
Conclusions:
- Surgical repair of TAPVC can achieve good long-term results, particularly in older infants.
- Age at operation is a critical factor influencing survival.
- Improvements in surgical management, such as addressing cardiac performance and postoperative bleeding, are crucial for reducing mortality.
- Continued refinement of surgical techniques is necessary to further enhance outcomes for TAPVC patients.
Abstract:
Thirty-five patients had complete repair of total anomalous pulmonary venous connection between 1 January 1968 and July 1974. The mean age of the patients was 5.8 months. The hospital mortality rate was 43%; six of seven patients less than one month of age died. There were no deaths in the nine patients over six months of age at the time of operation. Inadequate cardiac performance was responsible for eight of the nine deaths in patients operated on since 1 September 1971. Thirteen percent of the patients who left the operating room alive were reoperated on for bleeding early in the postoperative period. No patient has required tracheostomy since 1 September 1971. Three of the 20 long-term survivors have required reoperation. The late results are good. Ways of improving results in the future are discussed.
