Hypertrophic Cardiomyopathy, or HCM, is a thickening in the wall of the left ventricle. It causes scar tissue formation and makes it difficult for the ventrical to relax. If this condition is severe it can cause heart failure and accumulation of fluid in or around the lungs and making really hard for the cat to breathe. Also, the left atrium (the chamber behind the ventricle) enlarges, causing the blood to flow slower and the blood will start to clog. If the clog breaks loose from where its attached, it can travel along the aorta donw to the rear of the cat and cause paralysis and pain in the rear legs. The scar tissue caused by HCM can also induce abnormal electrical activity and can be manifested as arrythmia. This arrythmea can lead to a sudden death.
Some facts points to that males get this disease at an younger age and an often a more sever form.
HCM has been documeted in severel breeds such as Maine Coon, Ragdolls, Sphynx and sadly Bengal cats. In short, HCM could cause your cat to develop heart failure, die suddenly or experience paralyze and sever pain in their rear legs, also called saddle thromboembolus. You cannot detect Hypertrophic Cardiomyopathy without a scan.
That is why we at Spotted Sugar Rush makes yearly controls with HCM scan to ensure that our kittes is going to be as healthy as they can be. Although we do these scans, HCM could show later in their life, but most commonly this disease will develop in their 3-4 first years.
Both our girl has been scan for HCM:
