Acute myocardial infarction accompanying occlusion of left anterior descending and right coronary arteries / 대한내과학회지

ABSTRACT

Acute myocardial infarction (AMI) with simultaneous occlusion of two or three coronary arteries is extremely rare, but may cause devastating events unless immediate revascularization strategies are undertaken. We report an unusual case of AMI with ST-segment elevation in precordial leads. Thrombolysis was achieved successfully 2 hours after the onset of chest pain. Coronary angiography revealed residual heavy fresh thrombi at right coronary artery (RCA) as well as patent residual stenosis at left anterior descending coronary artery (LAD). Akinesia was demonstrated at anterolateral, apical, diaphragmatic, and posterobasal segments on left ventriculography. Large perfusion defects were proven at LAD and RCA territories on myocardial SPECT.
