Most patients remain asymptomatic, but for those with progressive symptoms, intervention is required. However, there are potential life-threatening complications associated with surgical intervention. We present a case of an extremely rare markedly aneurysmal LM to right atrial fistula treated with surgical ligation complicated by inferolateral ST-elevation myocardial infarction several days post-operatively treated successfully using mechanical aspiration thrombectomy, a stent-retriever, balloon angioplasty, and subsequent intravascular ultrasound-guided percutaneous coronary intervention with drug-eluting stent.
