Overview
Echocardiography is the imaging modality of choice in the diagnosis of hypertrophic cardiomyopathy.
Diagnostic Fefatures
- Left ventricular hypertrophy (LVH) most often in an asymmetric distribution,
- Thickening of the left ventricular wall in the absence of cavitary dilation and the presence of hyperdynamic activity (in fact there may be systolic cavity obliteration or near obliteration)
- Absnece of any other cause of left ventricular hypertrophy such as aortic stenosis or hypertension
Left Ventricular Wall Thickness
- The traditional definition requires a wall thickness > 15 mm.
- Borderline wall thicknesses of 13-14 mm must be distinguished from extreme variants of athletes heart
- There are some genetic variants that yield a normal wall thickness.
