Surgical correction of atrioventricular canal during the first year of life
Insights
Surgical correction of atrioventricular (A-V) canal defects in infants is effective. Early surgical repair offers excellent outcomes for infants with severe pulmonary hypertension.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease Surgery
Background:
- Atrioventricular (A-V) canal defects are serious congenital heart conditions.
- Intractable congestive heart failure necessitates surgical intervention in infants.
Purpose of the Study:
- To evaluate the efficacy of definitive surgical correction for atrioventricular (A-V) canal defects in infants.
- To assess outcomes in infants undergoing surgical repair for complete and partial A-V canal defects.
Main Methods:
- Retrospective analysis of eight infants under 1 year of age with A-V canal defects.
- Surgical correction performed due to intractable congestive heart failure.
- Follow-up assessment of surviving children postoperatively.
Main Results:
- One operative death and one late death occurred among the eight infants.
- Six surviving children demonstrated positive outcomes during follow-up periods ranging from 10 months to over 4 years.
- Successful surgical connection of A-V canal was achieved even in very small infants.
Conclusions:
- Definitive surgical correction of A-V canal defects is feasible and yields excellent results in infants.
- Prompt surgical intervention is recommended for infants with A-V canal defects not responding to medical management.
- Elective complete repair is strongly considered for all patients with this lesion and severe pulmonary hypertension within the first 1-2 years of life.
Abstract:
Eight infants less than 1 year of age with an atrioventricular (A-V) canal defect (five with the complete form and three with the partial form) had definitive surgical correction performed because of intractable congestive heart failure. At operation, the infants weighed 2.9 to 6.5 kg. There was one operative death and one late death. The six surviving children were all doing well when followed up 10 months to more than 4 years postoperatively. This small series demonstrates that complete connection of A-V canal is possible even in very small infants and that chances of success are excellent. The infant with this defect who is not progressing with medical management should undergo definitive surgical correction, and a strong argument can be made for elective complete repair in all patients with this lesion, who have severe pulmonary hypertension, during the first 1 or 2 years of life.
