Overview
There are two variants of hypertrophic cardiomyopathy: an obstructive variant, and a non-obstructive variant.
Obstructive Variant
If left ventricular outflow is present, then this syndrome has been known as Hypertrophic cardiomyopathy or HCM, Asymmetric septal hypertrophy or ASH, Hypertrophic obstructive cardiomyopathy, HOCM, Idiopathic hypertrophic subaortic stenosis or IHSS, familial isolated hypertrophic obstructive cardiomyopathy, familial isolated hypertrophic subaortic stenosis, familial or idiopathic hypertrophic subaortic stenosis, familial or idiopathic hypertrophic obstructive cardiomyopathy, primitive hypertrophic obstructive cardiomyopathy, primitive hypertrophic subaortic stenosis.
Non-Obstructive Variant
A non-obstructive variant of HCM is known as apical hypertrophic cardiomyopathy [1],which is also known as nonobstructive hypertrophic cardiomyopathy and Japanese variant hypertrophic cardiomyopathy or the Yamaguchi variant (since the first cases described were all in individuals of Japanese descent).
