Nonobstructive hypertrophic cardiomyopathy with left ventricular aneurysm: the role of cardiac magnetic resonance.

Hypertrophic cardiomyopathy with concomitant left ventricular aneurysm is rare and has important clinical implications, including an increased risk of sudden cardiac death. Most patients with this rare combination have obstructive hypertrophic cardiomyopathy, but we treated a 26-year-old woman who had nonobstructive hypertrophic cardiomyopathy and a family history of probable sudden cardiac death. In our patient, coronary angiograms showed distal occlusion of the left anterior descending coronary artery.
