摘要：

A 40-year-old man was found to have hypertrophic cardiomyopathy (HCM) with severe mid ventricular obstruction. The obstruction produced two distinct left ventricular chambers with an estimated 60 mmHg continuous wave (CW) Doppler intraventricular gradient. Pulsed wave (PW) Doppler showed high velocity systodiastolic flow from apex to base and flow from base to apex confined mostly to the second half of diastole. Cardiac magnetic resonance (CMR) showed midventricular obstruction, due to septal, parietal, and to an hypertrophic, double posteromedial papillary muscle; an apical aneurysm was detected. Aneurysm is underdiagnosed by echocardiography in HCM and an accurate anatomic definition is needed if surgery is planned; thus, a CMR should always be obtained in these patients.
