Abstract

A 69-year-old man presented to our hospital with chest pain. Two-dimensional transthoracic echocardiography showed hypertrophy of the left ventricle, mid-ventricular obstruction and an apical aneurysm. Color-flow imaging at the obstruction site on the apical four-chamber view demonstrated systolic flow reversal in addition to a paradoxical jet flow. The systolic flow reversal may have been caused by a decreased apical contractility and pressure during systole.
