Concerned now primarily with recovery. Will I need home care? Occupational therapy?
It depends on your conditions. Generally unlikely, but it also depends on your current fitness level. If you can walk a mile now, then I'd say very unlikely. The hospital should do an assessment of your needs before the discharge.
Physical therapy? In home labs??
Unlikely, but the hospital should have PT sessions with you during your recovery time there.
Will need in-home labs. The number seems to vary, but they'll want to see your bloodwork during at-home recovery.
Will I be able to feed myself? Go to the bathroom on my own? Or does it depend on how my surgery goes? Etc.
I'd think so. However, it could be quite helpful if somebody else cooks for you. Just "standing around" in the process could feel rather strenuous, and you might have to conserve the stamina for walking.
Are there tools or devices that people have found to be essential to have post-surgery?
I needed sunhats and walking shoes that could be put on easily. (Leaning over is not recommended.)
A shower seat? A grabbing tool? A cane?
I found the shower seat to be absolutely essential. It's probably not a universal experience. Depends on the stamina you'll have post-surgery, which is hard to predict. But a shower, even a lukewarm temperature, can feel like a strong exercise if the stamina is low. Couldn't find a medical shower seat with a proper height, and didn't want to swat too low in the (slippery) bathroom. So just used a narrow chair instead.
A hospital bed at home? Etc.
Quite a number of people found a reclining chair to be useful. But might not be absolutely necessary.
If you have any contributions or suggestions, please feel free to make them.
Some more pointers about what worked for me (and what didn't) are

I'm terrified of going under, not just of not pulling though, but alternatively of waking up in a new world where I'm suddenly in great pain and am entirely dependent upon others...
FWIW, I definitely felt "limited" a bit at first. However, it didn't feel like a "problem". I knew the reason perfectly well
And was re-gaining range and stamina every day. (Well, that's how it started. Eventually the rate of progress slows down, of course.)
Don't sweat it too much. It's a bit of a specialty club
But the number of people who get OHS is not small, about half a million per year in the US. The process is quite well practiced and exercised. The cardiac doctors and nurses really know what they are doing, you just need to follow their directions.
