Insights
Anomalous left coronary artery origin in infants can be successfully treated with direct aortic reimplantation surgery. This early surgical intervention significantly improves heart function and resolves heart failure symptoms.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Anomalous left coronary artery origin (ALCA) is a rare congenital heart defect.
- ALCA can lead to severe left ventricular dysfunction, mitral regurgitation, and heart failure.
Observation:
- Two infants, aged 6 months and 1 year, presented with ALCA.
- Both infants underwent surgical correction via direct aortic reimplantation of the anomalous coronary artery.
Findings:
- Post-surgical outcomes were satisfactory, with significant improvement in ventricular function.
- Mitral incompetence and congestive heart failure resolved.
- Myocardial perfusion and electrocardiographic patterns normalized.
Implications:
- Early surgical treatment for ALCA is recommended due to the condition's unfavorable natural history.
- Direct aortic reimplantation is considered the most effective surgical approach for ALCA in infants.
Abstract:
We report 2 infants aged 6 months and one year with an anomalous left coronary artery origin treated surgically at our centre with direct aortic reimplantation of the anomalous coronary. Evolution has been satisfactory, with a great improvement of ventricular function. The mitral incompetence and congestive heart failure have disappeared and myocardic perfusion electrocardiographic patterns were corrected. Because of the unfavorable natural course of the disease and the improvement in techniques of coronary revascularization in infants we recommend an early surgical treatment as soon as it be diagnosed. We consider that the most adequate surgical treatment is the direct aortic reimplantation of the anomalous coronary artery.
