|---|
A 50-year-old man presented with chest pain and recurrent episodes of syncope. Physical examination revealed a loud systolic murmur at the left sternal border with accentuation in erect position. Transthoracic echocardiography demonstrated severe asymmetrical septal hypertrophy and systolic anterior motion of the anterior mitral valve leaflet which were diagnostic for hypertrophic cardiomyopathy. Interestingly, color Doppler examination of the left ventricle showed aliasing of the left anterior descending coronary artery and intra-myocardial coronaries.
