Has anyone with diastolic dysfunction had bariatric surgery?

Hi! I am scheduled to have gastric sleeve surgery in September. I have diastolic dysfunction grade 1 and the idea of going under anesthesia makes me nervous. My surgeon is aware, as is my cardiologist and all have given me the green light. I realize that weight loss will likely improve the diastolic dysfunction and hopefully prevent full blown heart failure, so I am leaning towards going through with the surgery. I had a previous lapband (removed in 2014) and multiple surgeries which has caused adhesions/scar tissue, which will likely extend my total time under anesthesia.

Has anyone had WLS with heart disease? If so, did you have any cardiac complications during or post-surgery?
