MARTINEZ-CANO, Carlos A. et al. Anomalous origin of the anterior descending artery. Rev. Colomb. Cardiol. [online]. 2022, vol.29, n.1, pp.106-110.  Epub 22-Fev-2022. ISSN 0120-5633.  https://doi.org/10.24875/rccar.m22000125.

An anomalous origin of a coronary artery is considered when it does not originate from its respective Valsalva sinus. The estimated prevalence varies between 0.6% to 1.3%. While the majority will be asymptomatic, 20% may debut with arrhythmias, syncope, myocardial infarction or sudden death. It is presented a case of a 42 year old woman, with a history of high blood pressure. During exercise stress test for exercise prescription she presented a left bundle branch block. In absence of symptoms, it was decided to perform a coronary angiotomography that showed an anomalous origin of the anterior descending artery from the right Valsalva sinus. It was considered to perform coronary angiography to evaluate dynamic compression during the cardiac cycle, however, the patient did not accept additional interventions, so exercise restriction was indicated, metoprolol as drug treatment and follow up, not report complications to date. Coronary artery abnormalities are rare heart defects and within these abnormalities of the anterior descending artery are even less frequent. They are a frequent cause of sudden death in athletes. Its anatomical characteristics as the presence of symptoms will help to choose the patients who will benefit from surgical management.
