How to diagnose hypertrophic obstructive cardiomyopathy

Hypertrophic obstructive cardiomyopathy can generally be diagnosed by echocardiography, cardiac magnetic resonance imaging, and endomyocardial biopsy.

1. Echocardiogram

patients can be examined by echocardiography. If there is asymmetric ventricular hypertrophy but no ventricular enlargement and hypertension, valvular disease, etc. are excluded, hypertrophic obstructive cardiomyopathy can be initially diagnosed.

2. Cardiac magnetic resonance imaging. Cardiac magnetic resonance imaging

can detect localized or generalized thickening of the ventricular wall. Isotope delayed enhancement scanning can also see myocardial patchy enhancement.

3. Endomyocardial biopsy

can identify invasive cardiomyopathy by endomyocardial biopsy, which helps to exclude amyloidosis and glycogen storage.
