Plastic Surgery for Patient with an Enlarged Heart?

Denise,
Your question is impossible to answer without knowing more about your cardiac physiology.  Consultation with a cardiologist, who may recommend EKG, echocardiogram or other tests, is the only way to know the risks that your cardiomyopathy creates.  Good luck!

Dear Denise1971
It is great to hear that you are doing so well with your condition. It is not impossible for you to have surgery. However, provided you cardiologist, surgeon , and anesthesiologist are all on the same page, consider doing smaller procedures. For example it is possible to have liposuction and the fat transfer needed as part of the Brazilian butt lift all under local anesthesia.
Because you live in Los Angeles, you have access to excellent Cardiology. UCLA, Cedars, and USC have cardiology services with cardiologist who are focused on the care of individuals with Cardiomyopathy. UCLA for instance has a program where they actively monitor cardiac output in the process of optimizing drug treatment. So while you are focused on the simple question of "can I have surgery?" As Surgeons, we are first and foremost concerned about what is best for you and are you optimized medically for the state of your heart health. Answer this issue and it will be clear to your doctors where the risks of potential surgery are acceptable or too high.

Your condition is one that can get worse, or better, depending on your blood pressure control in the time since your diagnosis. So an updated exam, chest x-ray, and EKG would be needed.
Also, your internist/cardiologist may recommend some different medications to control your blood pressure in the immediate postop period. Some consideration may also be given to doing your case in a facility equipped for good monitoring and an overnight stay.
