[Complete correction of Fallot's tetralogy in infants. Preliminary results]
Insights
Complete repair of tetralogy of Fallot in infants can be a viable alternative to palliative shunts. Improved patient selection and surgical techniques are crucial for reducing mortality in this severe congenital heart defect.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
Context:
- Tetralogy of Fallot (TOF) is a complex congenital heart defect often requiring surgical intervention.
- Severe cyanosis and anoxic spells necessitate timely and effective treatment in affected infants.
Purpose:
- To evaluate the outcomes of complete surgical repair in infants with severe tetralogy of Fallot.
- To assess the feasibility and safety of primary complete repair versus palliative shunts.
Summary:
- Twenty-eight infants with severe TOF underwent complete repair, with ages ranging from 8 days to 11 months.
- Early mortality was observed in 6 out of 24 infants without other intracardiac defects, often due to indication or technical issues.
- Post-operative follow-up in survivors showed good results in most cases, with some requiring reoperation.
Impact:
- Enhanced accuracy in patient selection and surgical techniques can further reduce early mortality rates in TOF repair.
- Primary complete repair presents a promising alternative to palliative shunts, particularly in severe TOF cases.
- This approach may improve long-term outcomes for infants with complex congenital heart disease.
Abstract:
Complete repair was undertaken in 28 infants with severe forms of tetralogy of Fallot because severe cyanosis or anoxic spells. Age at operation ranged from 8 days to 11 months (mean: 4,4 months). Among the 24 cases without any other intracardiac defect, there were 6 early deaths related in 4 cases to a wrong indication or a technical error. Re-investigation was performed in 14 out of the 18 survivors from 3 weeks to 6 months post-operatively: the result is good in 10 cases, fair in 1 case, and poor in 3 cases requiring twice a reoperation with 1 further death and 1 good final result. More accuracy in selecting the surgical patients and improvement in operative techniques should result in a further decrease of our early mortality rate. Primary complete repair should therefore become a substantial alternative to the palliative shunts which results seem to be hazardous in the more severe types of the defect.
