[Cardiac rupture caused by myocardial infarction in the diagonal branch area: evaluation by cardiac multislice computed tomography: a case report].
A 75-year-old woman was admitted to the emergency room because of hypotension and loss of consciousness induced by cardiac tamponade. Electrocardiography revealed ST elevation and laboratory data showed elevation of serum creatine kinase and troponin I. The patient was referred to the cardiology department 5 days later. Cardiac catheterization revealed ventricular aneurysm in the anterior wall, significant stenosis (75%) in the left anterior descending coronary artery and subtotal stenosis (99%) in the diagonal branch. Cardiac multislice computed tomography suggested that the ventricular pseudoaneurysm was probably due to cardiac rupture caused by myocardial infarction in the diagonal area. Subsequently, aneurysmectomy and coronary artery bypass graft surgery were performed. Cardiac multislice computed tomography is useful for evaluating coronary artery and cardiac rupture.
