A Case Report of Yamaguchi Syndrome in a Saudi Male.

Apical hypertrophic cardiomyopathy, also called Yamaguchi syndrome, is a rare variant of hypertrophic cardiomyopathy. Yamaguchi syndrome is characterized by hypertrophy almost confined to the apical region of the left ventricle rather than the left ventricular septum. A case of 65-year-old Saudi man presented to the ER with angina, and the ECG, echocardiogram, and nuclear study confirmed the diagnosis with Yamaguchi. Reporting this case serves to help physicians broaden their vision in approaching patients with symptoms mimicking acute coronary syndrome.
