Insights
Anomalous origin of coronary arteries from the pulmonary artery, a rare congenital heart defect, can be associated with aortic coarctation. This complex condition is challenging to diagnose in living patients.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Pediatric Cardiology
Background:
- Anomalous origin of coronary arteries from the pulmonary artery (AOCAP) is a rare congenital cardiac anomaly.
- Aortic coarctation is a congenital narrowing of the aorta.
Observation:
- This report details two cases of AOCAP associated with aortic coarctation.
- Diagnosing this combined anomaly in living patients presents significant challenges.
Findings:
- The association between AOCAP and aortic coarctation is difficult to diagnose preoperatively.
- Patients with isolated aortic coarctation showing poor outcomes post-coarctectomy may have this underlying anomaly.
Implications:
- Consider AOCAP in patients with isolated aortic coarctation who do not improve or worsen after coarctectomy.
- This highlights the importance of considering rare anatomical variations in complex congenital heart disease cases.
Abstract:
Single trunk anomalous origin of both coronary arteries from the pulmonary artery is a rare congenital cardiac anomaly. We report on 2 cases of its association with aortic coarctation, the diagnosis of which in living patients is very difficult. We think that the possibility of this anatomic arrangement should always be considered in patients with isolated aortic coarctation whose clinical condition seems impaired rather than improved after an apparently successful coarctectomy.
