Burmese and heart problems
My cat Morag, who is a Burmese, was diagnosed with severe HCM by my regular
vet about a month ago, after having undergone an ultrasound. Yesterday she saw a cardiologist at the veterinary hospital here, and after an ultrasound was performed using a machine with a higher resolution than the one previously used, the cardiologist said that she has a very unusual heart condition that doesn't fit into any textbook. She actually only has mild HCM, but the problem is that her heart is abnormal. Her left atrium is huge, and her left ventrical is just abnormal. The wall bulges inward in several places and also the ventricle contains crap, stuff that strings from one side of the chamber to the other. She doesn't have HCM, DCM, or RCM. The cardio said that what she has is rare, nobody knows what causes it, how to treat it, or what the prognosis is. All that can be done is to treat the symptoms, so try to keep the lungs clear and try to prevent her from throwing a clot. There are some theories of how the heart became this way - some say it's due to inflammation, some say scar tissue from a previous viral infection, some think it's auto-immune in nature, and some think it's congenital. The jury is still out. The cardio says that she has seen perhaps a handful of cats in her career with a presentation similar to Morag - the most interesting point she made was that out of that handful of cats, the cat with the heart that most closely resembles Morag's was also a Burmese. So I'm wondering if anyone has heard of this before in Burmese cats (or in any cat). |

So I'm wondering if anyone has heard of this before in Burmese cats (or in any cat). Has endocardial fibroelastosis been ruled out? -- EFE is a congenital defect/familial disease in the Burmese. "the ventricle contains crap, stuff that strings from one side of the chamber to the other." Sounds a lot like endocardial fibroelastosis -- which is an overgrowth of elastic and fibrous fibers in the inner lining of the left atrium and ventricle. "Her left atrium is huge, and her left ventrical is just abnormal." ""Reported findings (in cats) with EFE include dyspnea, systolic murmur of mitral insuffiÂ*ciency, gallop rhythms, tachycardia, hydrothorax, asciÂ*tes, ECG changes (especially increased R wave voltage), and severe LA and LV enlargement on radiography. At necropsy, the heart weight is increased; there is dilaÂ*tion of the LV and to lesser degree, the LA; and the LV wall is thin. Characteristically, the LV endocardium is diffusely thickened and appears gray-white and opaque. Histologic features are striking and reveal an LV endocardium thickened by dense collagenous and elastic fibers.""
