Left main coronary artery aneurysms are very infrequent (0.1%) and the majority is related to atherosclerotic obstructive lesions. We describe a young male having no conventional coronary risk factors presenting with acute inferior wall myocardial infarction. Coronary angiography revealed a prominent aneurysm of the left main coronary artery with selective extension towards the proximal left circumflex artery without associated coronary lesions.

“…Es más frecuente en hombres, con una proporción de 1.5-4:1, y su localización es, en orden de frecuencia, la arteria coronaria derecha, la arteria descendente anterior y la arteria circunfleja. El tronco de la coronaria izquierda es el sitio menos afectado, siendo la prevalencia de los aneurismas en esta localización del 0.1% 1,2 .…”

Los aneurismas coronarios son una patología poco frecuente, con una incidencia anual del 1-2%. Su origen puede ser ateroesclerótico, congénito o por otras causas menos habituales. Su manifestación inicial puede ser el infarto de miocardio y la muerte súbita, como consecuencia de su rotura o por la existencia de trombos intracoronarios. El método diagnóstico de elección es la coronariografía. Sin embargo, las técnicas no invasivas, como la ecocardiografía transtorácica incluyendo la modalidad tridimensional y transesofágica, la resonancia magnética y la tomografía computarizada pueden tener un papel relevante en la detección y el seguimiento de estas anomalías. Varón de 20 años sin antecedentes de importancia que acude al servicio de urgencias por presentar precordalgia de 24 h de evolución, con datos sugestivos de edema agudo pulmonar. Se realizan electrocardiograma y determinación de enzimas cardiacas, que reportan un infarto agudo al miocardio anterior extenso. Se procede a valoración por hemodinamia y realización de angioplastia coronaria, reportando tronco izquierdo deformado, aneurismático, con circulación de arteria descendente anterior ausente, con un flujo distal TIMI 0. El paciente presenta choque cardiogénico, con evolución tórpida que evoluciona a paro cardiorrespiratorio y disociación electromecánica, sin respuesta a reanimación cardiopulmonar avanzada.

“…[1] However, giant aneurysm are rare lesions, whose true incidence is unknown, because they tend to be asymptomatic. A myriad of presentations have been reported in the literature such as acute coronary syndromes, [2] heart failure, [3] superior vena cava syndrome, [3] right ventricular outflow obstruction, [4] cardiac compression, [5] sudden death [6] and cardiac tamponade [7] due to rupture of the aneurysmal sac and hemopericardium. We describe tamponade physiology in an unruptured giant right coronary artery (RCA) aneurysm.…”

A 65-year-old woman presented with a history of dyspnea and atypical chest pain. She was diagnosed with a non-ST-segment elevation myocardial infarction due to a giant right coronary artery aneurysm. After a failed percutaneous embolization, she was scheduled for right coronary artery aneurysm resection, posterior descending artery revascularization and mitral valve repair. During the induction of anesthesia and institution of mechanical ventilation, the patient suffered cardiovascular collapse. The transesophageal echocardiographic examination revealed tamponade physiology owing to compression of the cardiac chambers by the unruptured aneurysm, which resolved with the sternotomy. The surgery was carried out uneventfully.
