Hi everyone
In this we will discuss about echocardiogrphy features of HCM ( Hypertropic Cardiomyopathy)
HCM is primary genetic disease of heart muscle in which asymmetrical hypertrophy developed in some regions of left ventricle
It occur 1/500 case
Most common cause of sudden death in athletes and player 
In echo there is 
Thickening of IVS , posterior wall and other regions
IVS/PW thickness ratio is more then 1.3 in normal and 1.5 in hypertensive case
Small lv cavity and LVOT
Dilated LA, posterior directed MR het, elongated anterior mitral leaflet
Systolic anterior motion (SAM) of mitral valve seen in m mode 
In short axis view we aortic valve and thickness of LV
Gradient across LVOT is measured in apical five chamer with CW mode 
It shows dagger shaped gradient and  more than 30 mmHg
Both favour HCM
IVS thickness increased near basal part and LV cavity shape become like banana shape 
Systolic function remains normal but some diastolic dysfunction may present
Thanks
