Hi @leenag,
Welcome to Mayo Clinic Connect. You posted in the HCM group, so I am going to assume that you have this condition?

Our little support group has many members who have had open heart surgery, specifically a septal myectomy, to reduce the amount of tissue which causes the LVOT obstruction, and thereby reduces the symptoms of HOCM, the obstructed version of HCM.
There are the apical HCM/HOCM people too, and they have a whole unique set of circumstances they have to deal with.

Here are a couple of links to check out for more detailed information:

And here is one from a source outside the Mayo Clinic that many others find useful:

Each one of us is different, and each one of us that had open heart surgery, or are planning to have it, have gone through lots of testing and studies that concluded with the physician making the recommendation for open heart surgery.
Different protocols from different facilities are in place as well.

Again, no two are alike, but we all have much in common.
Medications such as beta or calcium channel blockers may be tried for symptom relief, and the newer drug Camzyos may be suggested as well.

Do you have an HCM expert that you are seeing currently?
How long have you known you have this diagnosis?
Are you otherwise healthy?
