Idiopathic apical left ventricular aneurysm in hypertrophic cardiomyopathy. Report of 3 cases, and review of the literature.

In a review of 160 cases of hypertrophic cardiomyopathy which underwent hemodynamic studies, 3 cases of apical aneurysm of the left ventricle of unidentifiable etiology were found. Bearing in mind the rarity of apical idiopathic left ventricular aneurysms, the authors believe this association with hypertrophic cardiomyopathy is of some interest and point out the possible pathogenetic mechanisms.
