Case report

A 79-year-old housewife experienced sudden-onset chest tightness and was diagnosed with an inferoposterior wall myocardial infarction (MI). Coronary angiography showed two-vessel coronary artery disease with lesions of 70–80 % stenosis of the proximal left anterior artery (LAD) and total occlusion of the proximal left circumflex artery (LCX). An emergent percutaneous coronary intervention (PCI) was performed for the culprit lesion of the proximal LCX. It took about 6 h from chest tightness to revascularization. Transthoracic echocardiogram (TTE) showed impaired left ventricular performance (LVP), with mild mitral regurgitation. Two weeks later, a chest radiography showed progressive left lower lung consolidation. Uncontrolled pneumonia was resent initially; however, symptoms of advanced heart failure progressed. Therefore, PCI was performed for the lesion of the proximal LAD. Unfortunately, symptoms of heart failure did not improve after total coronary revascularization and...
