Congenital cardiac anomalies: one-stage repair in infancy
Insights
This study evaluated one-stage operative repair for congenital cardiac anomalies in infants. The approach showed acceptable results for ventricular defect and tetralogy of Fallot, justifying its use when surgery is needed.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Disease Treatment
Background:
- Evaluating the efficacy of a single-stage surgical repair for congenital cardiac anomalies.
- Assessing outcomes in infants and young children requiring operative intervention for heart defects.
Purpose of the Study:
- To determine the advisability of a preferred treatment plan using one-stage operative repair for congenital cardiac anomalies.
- To compare one-stage repair with palliative operations and staged repairs.
Main Methods:
- A cohort of 74 patients aged 14 hours to 24 months underwent one-stage operative repair.
- The study period was from February 1, 1972, to September 15, 1974.
- Analysis of results based on specific cardiac anomalies: ventricular defect, tetralogy of Fallot, transposition of the great arteries, and miscellaneous defects.
Main Results:
- Acceptable results were observed for ventricular defect and tetralogy of Fallot.
- Improved outcomes are anticipated for transposition of the great arteries by adjusting age and technique.
- Survival and improvement were achieved in 51 out of 74 infants, despite an initial 20% mortality.
Conclusions:
- One-stage operative repair is a direct and effective approach for certain congenital cardiac anomalies.
- Persistence with one-stage correction is justified when operative intervention is required.
- Further refinement in technique and patient selection may improve outcomes for complex anomalies like transposition of the great arteries.
Abstract:
A proposed preferred treatment plan consisting of one-stage operative repair of congenital cardiac anomalies whenever complete correction was feasible and operative intervention required was tested during the period February 1, 1972, to September 15, 1974. Experience with 74 patients aged 14 hours to 24 months allows some conclusions to be made regarding the advisability of this approach. For patients with ventricular defect and tetralogy of Fallot, this approach has quite acceptable results and certainly is more direct than palliative operations and second-stage repair. The hypothesis is more difficult to justify in patients with transposition of the great arteries. By avoiding repair in patients under 4 months of age and using a better technique for placement of the intraatrial partition, improved results are anticipated. In the miscellaneous group of anomalies, results depend upon the complexity of the defect and the ability to achieve accurate anatomical correction. After an early mortality of 20% and some late deaths, survival and improvement resulted in 51 of these babies. These results justify persistence in the choice of one-stage correction when operative intervention is required.
