Left ventricular aneurysm associated with apical hypertrophic cardiomyopathy

A 47-year-old man with apical hypertrophic cardiomyopathy and an apical left ventricular aneurysm with palpitation as the initial manifestation is described. There was no intraventricular pressure gradient. The aneurysm is suggested to be a part of the myocardial disease or to be caused by myocardial bridging of the left anterior descending coronary artery demonstrated by angiography. The 24-hour ambulatory ECG recording showed only isolated ventricular ectopic beats and the clinical course has been favorable during 20 months without therapy.
