Changes

The force of the left ventricular contraction reduces afterload and reduces end-systolic volume to zero in some cases.  This is '''cavity obliteration'''.

*[[Endocardial - Pathology#Atrial_thrombosis|Thromboembolic disease]] is a frequent complication.  The thromboemboli most often impact in the femoral arteries manifesting as an acute hindlimb paralysis.

Described clinically in cats and cattle.  There is fibrosis and thickening of the left ventricle which allows decreased filling and so diastolic dysfunction.  There is left atrial dilation to cope with the increased difficulty in filling the left ventricle and this predisposes to [[Endocardial - Pathology#Atrial_thrombosis|thromboembolic disease]].
