This patient suffered from a condition called Subaortic Stenosis, narrowing of the left ventricle of the heart just below the aortic valve through which blood must pass on its way up into the aorta. The narrowing (by forming a fibrous ring) cuts the flow of blood. Subaortic stenosis may be congenital (present at birth) or acquired as part of a particular form of heart disease known as "idiopathic hypertrophic subaortic stenosis" (IHSS).Photos sent by @mmedoshaker
