RESUMO
The anomalous origin of the coronary arteries (AOCA) has several patterns. Most are functional and asymptomatic. However, some are associated with persistent chest pain and sudden cardiac death. Multiple imaging techniques are available for the assessment of AOCA. We present a report of 4 cases with AOCA, including the anomalous aortic origin of a coronary artery (AAOCA) of the right coronary artery, AAOCA of the circumflex artery, AAOCA of the left anterior descending artery, and AAOCA of the circumflex artery with retroaortic trajectory, in which the clinical manifestations throughout the cases are discussed, highlighting the similarity among patients despite having different patterns. Multiple imaging techniques are indispensable for assessing AOCA, where transthoracic echocardiogram is the first-line study, and cardiac computed tomography provides detailed cardiac and coronary anatomy.
