My mom had open heart surgery approx. 1 month ago to remove an atrial myxoma that had damaged the mitral valve. They replaced the valve and damaged an artery during the removal of the myxoma, so they also did a by-pass. She was slow to wake up from anesthesia, but started making great recovery. She was able to shower, cook, drive, etc. Then last week, literally overnight, she developed severe tremors when she would engage in any kind of movement. She shakes, has terrible balance, no energy and speech is slowed. I ve had her to the ER twice, and they say all her labs are normal. Even did a cat scan and it was normal. They are referring her to a neurologist. Any ideas what could cause this? She had been doing so well, now she can t even stay home alone.
Hello, I passed carefully through your question and would explain that your symptoms could be related to a stroke, although her CT scan is normal.  For this reason, I would recommend performing a brain MRI and consulting with a neurologist.  I would also recommend performing a new cardiac ultrasound in order to examine her heart function and structure again.  Hope I have answered your query. Let me know if I can assist you further.
