[A case report of an acute myocardial infarction with simultaneous occlusion of circumflex and right coronary artery]. / Infarctus du myocarde secondaire à l'occlusion aiguë simultanée des portions proximales de la circonflexe et de la coronaire droite: à propos d'un cas.

Acute myocardial infarction due to simultaneous occlusion of two major coronary arteries is a rare phenomenon. We report a case of a 53-year-old man with many cardiovascular risk factors, who presented to the emergency with an acute coronary syndrome with ST segment elevation in anterior and inferior leads, complicated by atrioventricular block and cardiogenic shock. The coronary angiogram showed proximal occlusion of left circumflex artery and right coronary artery. Both arteries were treated successfully with thrombectomy followed by coronary stent implantation. Some similar cases have been reported, but the exact physiopathological mechanism is unknown. There is no clear strategy established for the therapeutic coverage, however, percutaneous revascularisation seems to be actually appropriated treatment.
