Multimodality Assessment of Congenital Coronary Anomalies
Published by American Society of Echocardiography
Summary
AI-generatedCongenital coronary artery anomalies are recognized as important lesions with significant potential morbidity and mortality, including sudden cardiac death. Multimodality imaging techniques have replaced cardiac catheterization as the primary tool for characterization of most congenital CA anomalies in children.
Key Takeaways
- 1Echocardiography (TTE) is the initial screening and diagnostic tool of choice for suspected congenital coronary anomalies.
- 2Cardiac computed tomography (CCT) and cardiac magnetic resonance (CMR) are essential complementary techniques for confirming complex anatomy, assessing intramural courses, and defining spatial relationships.
- 3Delineating the exact origin and course of the anomalous coronary is critical for surgical planning and risk stratification in isolated CA anomalies like AAOCA and ALCAPA.
- 4In complex congenital heart diseases (e.g., TOF, truncus arteriosus), precise preoperative delineation of a coronary artery crossing the right ventricular outflow tract (RVOT) is vital to prevent surgical injury.
- 5Coronary angiography remains critical prior to right ventricular decompression in PA-IVS to evaluate for RV-dependent coronary circulation.
Key Recommendations
Anomalous Aortic Origin of a Coronary Artery
- REC-AAOCA-1
TTE should be the initial screening tool for suspected AAOCA, particularly in forms that are associated with myocardial ischemia (those with an interarterial course).
Diagnosis - REC-AAOCA-2
When an interarterial AAOCA is identified, delineation of anomalous ostial origin/size and course should be confirmed with CCT and/or CMR.
Diagnosis
Anomalous Pulmonary Origin of a Coronary Artery
- REC-ALCAPA-1
TTE should be the primary screening tool and is usually diagnostic in suspected ALCAPA in infants and children.
Diagnosis - REC-ALCAPA-2
Confirmation of the diagnosis using CCT or CMR should be reserved for cases where the anatomy is unclear; cardiac catheterization is rarely needed for diagnosis.
Diagnosis
Isolated Congenital Coronary Artery Fistulas
- REC-CAF-1
When intervention for a significant CAF is planned, delineation of origin, course and exit should be confirmed with cardiac catheterization, CCT or CMR.
Clinical Assessment
Transposition of the Great Arteries
- REC-TGA-1
Postoperative CCT, CMR, and/or cardiac catheterization should be performed when there is suspicion of coronary compromise.
Clinical Assessment
Pulmonary Atresia With Intact Ventricular Septum
- REC-PAIVS-1
Coronary angiography should be performed prior to any interventions that would result in decompression of the RV.

Safety & Contraindications
Contraindications
- Implanted pacemakers or cardioverter defibrillators (relative contraindication for CMR)
- Advanced renal disease (contraindication for gadolinium-based contrast in CMR)
Monitoring Guidance
Serial TTE is recommended for monitoring coronary ectasia, ventricular function, and regional wall motion abnormalities post-intervention or in conditions like anomalous left coronary artery from the pulmonary artery (ALCAPA).
