CASE PRESENTATION The patient is a 59-year-old man, (height: 50 4, weight: 143 lbs), who has been moderately active throughout his life and had no known coronary risk factors and was asymptomatic until 4 months ago, when suddenly he started having chest pains. He did not seek medical advice till 10 days later at which time he started having increasing shortness of breath and swelling of the legs. He was seen in outside clinic and was started on aspirin and low doses of a diuretic and a betablocker. His symptoms progressed and he was referred to our medical center.

His blood pressure was 100/70 mmHg the heart rate of 60 bpm and the oxygen saturation was 93% on room air. The electrocardiogram showed sinus rhythm with QS pattern in II, III, aVF and V6, without ST-segment elevation (Figure 1). A 2-dimensional echocardiogram showed inferolateral left ventricular (LV) aneurysm and mild mitral regurgitation (Figure 2). The left ventricular ejection fraction (EF) was 42%. Rest/stress (vasodilator) gated SPECT myocardial perfusion imaging using Tc-99m labeled tracer was performed, which showed a severe and large fixed perfusion defect in the inferior and lateral walls of the LV (Figure 3). A repeat study with Thallium-201 (rest/ redistribution) showed a similar perfusion pattern (Figure 4). A multislice cardiac tomography (MSCT) showed inferolateral LV aneurysm (Figure 5). The aneurysm measured at diastole 40.9 mm 9 56.4 mm in the axial view; 53.9 mm 9 25.1 mm in the sagittal view and 49.6 mm 9 28.8 mm in the mid ventricularshort axis view. The maximum diameter from the aneurysm to the LV septal wall was 92.6 mm. No
