The condition of having enlarged muscles on the left side is called left ventricular hypertrophy. If it's caused by your mitral valve regurgitation, then it will get labelled as LVH as a consequence of MVR.
If it has no obvious cause (ie: they don't think your regurgitation is bad enough to cause it, and you don't have high enough blood pressure to cause it, etc.) then they'll call it hypertrophic cardiomyopathy.
The treatment will depend on the cause. (Mine was a consequence of MVR so surgery to repair the MV was recommended.)
As your cardiologist says, swelling of the left side of the heart can be caused by many things, most of which can be managed by medication. But you and you cardiologist will have a clearer picture when you have a confirmed diagnosis. I doubt that cooked goose will be the problem!🙂
Meanwhile you might want to thing about small changes you can make to improve your general heart health as these will be helpful whatever answers your cardiologist comes up with later.
Sounds like you may have a septal bulge, as I have been diagnosed. My cardiologist is reluctant to put this down to HCM, which is hereditory, as I do not have sufficient symtoms... yet. Also an MRI scan showed that I do not have the heart muscle structure usually associated with HCM. So welcome to the limboland of HCM or not.
I have this too, was discovered on echo when investigating my angina. Had cardiac mri to check for hypertrophy and it was normal, just something they have to check for, so don't panic, wait until you get a proper diagnosis.
