Intracoronary thrombolysis and balloon angioplasty can be an effective treatment for acute myocardial infarction caused by coronary embolism in patients with hypertrophic cardiomyopathy.
We report a case of acute myocardial infarction due to coronary embolism in a patient with echocardiographically documented hypertrophic cardiomyopathy. Emergency coronary arteriography revealed embolic occlusion of the proximal left circumflex coronary artery and the first diagonal branch. Intracoronary thrombolysis with urokinase and subsequent balloon angioplasty was successful. Transesophageal echocardiography revealed thrombus in the left atrial appendage. Coronary arteriography performed on the 46th hospital day revealed a patent left circumflex coronary artery and diagonal branch. The patient was discharged uneventfully.
