Six-Month Progression of Massive Left Ventricular Pseudoaneurysm

A 59-year-old male patient was referred to our centre after a scheduled outpatient echocardiogram demonstrated that he had a left ventricular (LV) pseudoaneurysm. The patient reported chest pain and dyspnea on exertion. He had a history of delayed presentation myocardial infarction (MI) 6 months prior, with negative cardiac troponin at presentation. At the time of MI, he was a smoker but had no other past medical history of note. Percutaneous intervention, with placement of a drug-eluting stent to a severe mid left anterior descending artery lesion was performed, and thrombotic occlusion of the principal diagonal artery was medically managed.
