Abstract
The end stage of hypertrophic cardiomyopathy is generally considered to be systolic ventricular dysfunction. The majority of patients with hypertrophic cardiomyopathy showed cavity dilatation, wall thinning, and symptoms of heart failure. Repetitive myocardial necrosis may be responsible for the gradual deterioration due to congestive heart failure over the course of several years. Myocardial necrosis in patients with hypertrophic cardiomyopathy is not uncommon, even in the absence of significant coronary artery disease. Here, we describe two cases of hypertrophic cardiomyopathy complicated with myocardial necrosis in the absence of significant coronary artery disease. With comprehensive cardiac MR imaging, we can demonstrate the potential pathophysiologic mechanism of myocardial necrosis in hypertrophic cardiomyopathy.(Korean J Med 73:S961-S965, 2007)
Key Words: Hypertrophic cardiomyopathy, Myocardial necrosis, Normal coronary artery
