This is the gorgeous Boomer, a six year old Ragdoll🐈⬛
Boomer came in to see us in January after he’d had some concerning episodes. His owner reported he seemed to go floppy- with one episode worryingly progressing to him becoming almost unresponsive.
Boomer was admitted for urgent tests, which revealed he had a thickening of his heart muscle. The most common reason for this in Ragdoll cats is a degenerative condition called hypertrophic cardiomyopathy (HCM) which unfortunately has no cure and ultimately leads to heart failure. However Boomer’s signs didn’t quite match the signs for HCM and so Sam performed further tests. His diligent approach meant he discovered Boomer likely had a different cause for his heart thickening, one with a better prognosis, TMT.
Transient myocardial thickening (TMT) is a much less common cause of thickened heart muscle. The underlying cause is not always identifiable but with the right medication cats can make a full recovery.
And we’re delighted to report that’s exactly what Boomer did. Thanks to Sam & the team’s excellent care, Boomer’s recent tests show his cardiac parameters are now back to normal.
Well done to his fantastic owners and all involved with his care👏
