Pulmonary arteriovenous fistula as a possible cause for myocardial infarction

Abstract

Although the most common cause for coronary embolism is atrial fibrillation, we should take other conditions into consideration that, despite their low frequency of occurrence, need to be discarded to be able to establish a definitive treatment. Arteriovenous malformations like the case presented here are some of these conditions. A 36-year-old woman with Rendu-Osler-Weber syndrome and recurrent and spontaneous epistaxis as the only personal medical history presented to the ER with oppression in her middle chest and pain radiating towards her left upper limb and back with concomitant vegetative symptoms. The electrocardiogram confirmed the presence of a subepicardial lesion in leads V2-V3 with high-sensitive troponin peak values of 9148 pg/mL.
