Abnormal origin of the coronary arteries by echocardiography. And then what?

Abstract Funding Acknowledgements Type of funding sources: None. Introduction The anomalous origin the coronary arteries from opposite sinus (AOCA) is increasingly recognized. most frequent diagnosed by echocardiography circumflex artery arising right Valsalva with a retroaortic course. Classically believed to be low-risk malformation, nevertheless, whether this anomaly associated other high risk features (coexistence high-risk AOACA, acute take off angle, intramural course, etc) not easily identify unknown. Objectives objectives study are know prevalence anomalies echocardiography, determine use additional diagnostic tests and evaluate coexistence / or characteristics. Materials methods A retrospective search AOCA diagnosis was performed among reports outpatients in complexity cardiology center between March 2018 December 2021. clinical history investigated if led further testing (coronary Angio CT Ischemia test) these studies provided clinically relevant information. Results Of total 26260 echocardiogram investigated, 50 presented suspected (0. 2%), 49 course 1 left subpulmonary 18 angiography (36%) 13 stress (26%) were requested. In 17 patients (98%) confirmed (true positive). 4 OAAC angiography, important information (2 anterior descending, interarterial an angle take-off aortic wall ‹45°). Conclusion uncommon finding them low risk. variant adds identifying abnormalities evaluating angulation abnormal arteries.
