Co-existing aortic stenosis and secondary hypertrophic cardiomyopathy manifested by an hourglass left ventricle. Successful treatment with verapamil.

A patient with moderate aortic stenosis had severe hypertrophy and a typical hourglass appearance of the left ventricle. His effort-induced angina and dyspnea responded to treatment with verapamil. We suggest that the aortic stenosis resulted in secondary hypertrophic cardiomyopathy which may be treated by calcium antagonists.
