GONCALVES, Alexandra et al. Anomalous origin of left coronary artery arising from the rigth sinus of valsalva with interarterial course, in a 75 years-old patient . Arq Med [online]. 2006, vol.20, n.4, pp.111-113. ISSN 2183-2447.

Anomalous left coronary artery (LCA) arising from the right sinus of Valsalva with a course between the aorta and the pulmonary trunk is a rare condition associated with sudden death even in the absence of other cardiac abnormalities. We present a 75 year-old woman admitted with a respiratory infection, heart failure, and thoracic pain. Heart perfusion scintigraphy showed a transient perfusion defect on the inferior and septal wall. Coronary angiography revealed that LCA arose from the right coronary sinus, with subsequent coursing between aorta and pulmonary trunk. Multislice Computered Tomography confirmed the interarterial course. Considering patient age and comorbilities, the decision was medical treatment. Clinical satisfactory results were achieved, but 6 months later the patient suffered sudden death of unknown cause.
