4 Interesting Facts of Anomalous origin of the left coronary artery from pulmonary artery
- Congenital abnormality in which the left coronary artery arises from the pulmonary artery rather than the aorta
- Manifestations often develop with decrease in pulmonary arterial resistance in the first few weeks of life, presenting with symptoms and signs of congestive heart failure similar to myocarditis
- Diagnoses are difficult to differentiate on clinical grounds alone; ancillary studies (eg, echocardiogram) are often required to aid in differentiation
- Differentiate with echocardiography and identification of anomalous origin of the coronary artery; angiography is the gold standard for diagnostic confirmation
