Acute Myocardial Infarction Secondary to Bacterial Endocarditis in a Child with Congenital Aortic Stenosis

Although peripheric emboli is a common complication of bacterial endocarditis, emboli to the coronary arteries resulting in myocardial infarction are rare, especialy in childhood. We describe a 14-year-old child with congenital aortic stenosis who developed non-Q moycardial infarction secondary to the embolic complication of bacterial endocarditis. His echocardiographic examination revealed a vegetation under the aortic valve and his valvular gradient was found to be 45 mmHg. Pneumococi were cultured from his blood. In the eight day of hospitalization the patient developed non-Q myocardial infarction. The diagnosis was made on the basis of ST segment depression in leads I, II, III, aVF, aVL, V2-6 and significant elevation in myocardial enzymes. The patient died due to pulmonary edema eight hours after the diagnosis of myocardial infarction.
