A reply for Peggy...
If you have mitral or aortic stenosis, your doctor will likely advise against snorkelling (I go down 30+ feet regularly). Most will faint outright if you mention scuba diving.
Absolutely run that by your cardiologist before leaving.
After your surgery, you may very well be able to pick up scuba diving again, if you can find an enlightened cardiologist who will work with you to make sure your body's ready. There are some post-vr divers on this site.
The altitude thing is about oxygen intake, and the possibility of creating a potentially risky anoxic situation for a damaged heart that would not have happened if you stayed home.
Best wishes,
