Echocardiogram in hypertrophic cardiomyopathy, parasternal long axis view
(Click on the image for an enlarged view)
Echocardiogram in parasternal long axis view showing the asymmetric septal hypertrophy. The interventricular septum (IVS) is much thicker than the left ventricular posterior wall (LVPW). Septal to posterior wall ratio of more than 1.5 is highly suggestive of hypertrophic cardiomyopathy (HCM). Here [...]

Indian Hypertrophic Cardiomyopathy Registry

Posted by: Johnson Francis on: 25 Dec, 2009

Hypertrophic cardiomyopathy has an incidence upto 1:500 as per certain studies and has a propensity for sudden cardiac death. The proposed national registry of hypertrophic cardiomyopathy is aimed at compiling important information about the disease in India. Those centers interested in participating in the registry are requested to register their contact details at http://www.hcmregistry.in/ so [...]

Hypertrophic obstructive cardiomyopathy – echocardiographic profile

Posted by: Johnson Francis on: 25 Sep, 2009

Hypertrophic cardiomyopathy is an autosominal dominant disorder with 50% involvement of first degree relatives, though the extend of involvement is variable. The hall mark of the disorder is severe hypertrophy of the left ventricle, even though biventricular forms may be seen rarely. In the obstructive variety of hypertrophic cardiomyopathy, asymmetric hypertrophy of the interventricular septum [...]
