Hello there @palni,
I extend my welcome along with others. That's a great question, and it looks like others have chimed in already. If I may add my experience to their list?

@colleenyoung gave you information that is right on in my opinion. From what I have learned, the Mayo Clinic offers people many options for diagnosis, treatment, surgery and being followed post-op. In some cases, you are sent home with a big 'ol packet of information to share with your hometown doctor. You got what you needed and your local doctor can move forward with your treatment plan.

But if you happen to need a little more hand holding and want to be certain you are ready to be turned loose again to your own doctor, Mayo Clinic, in my case, offered to monitor me and I even got to "meet" Dr. Steve Ommen online for his input in my post op course.
I was having trouble adjusting to certain meds after open heart surgery. This wonderful man helped me get through med changes and eventually told me to go off completely. I had lost confidence in my local options after my not-so-positive adventures in HOCM. After being at Mayo Rochester, I was spoiled and was afraid to be cut loose completely. They held my hand until I was ready to let go. It's like once you are in with Mayo...you are in for life! And that is what I experienced. I got my life back and am forever grateful.

I am in the Hypertrophic Cardiomyopathy support group and found them to precious and invaluable before, during and after my open heart surgery journey. May I ask what brings you to Cardiology at the Mayo Clinic?
