Two ways: open the constricted channel with a balloon and keep it open with a stent or completely bypass it with a vein or artery.

Honestly, I have no recent experience in current cardiac surgery practice, but I know even less about current anesthesia practice. It will be general anesthesia and you will be put to sleep. How and with what technique I cannot say.
Good luck.

The simple answer is no. I can imagine where placement of a stent could interfere either circulation to the SInus node and atrioventicular node but I’ve never heard of that. So my answer is very unlikely

Depends on wear the stent is for. Heart, peripheral vascular but overall the answer is No. stents do not shorten your life and may help you avoid a major vascular operation or heart surgery.

Depends. If they are opening his chest it will takE about a week. If they do it through a scope it will probably be less. Four things you need to do: he has to cough and deep breathe a lot, make sure he is up and about a lot. Good pain control. Good nutrition. Emotional support as patients get a little depressed after a big operation of any kind. Oops that was five things. I wish him well

It's serious surgery, but over the years, it has become less risky. As a surgeon, I attributed 3 reasons for a bad outcome: the unpredictability of biological systems, an act of God like a tornado hitting the OR, or pilot error like you forgot to put the wheels down before you landed. The first two no one has control over; the last one just never happens in this day of great training, evolved expertise, and experience. I predict he will do fine. Even though the prospect is terrifying.

There are many reasons for surgery over stents and vice versa. If the patient is stable and the episode is not jeopardizing good functioning heart muscle you can do elective stents even urgent stents especially if the situation is stable but could become unstable. Urgent or emergency bypass is for a situation where things are unstable or might become so unpredictability. If there is active muscle dying you want to save it as quickly as possible. Lastly if there are a lot of coronary arteries with high grade obstruction. Just bypass all of then at the same time. Hope that answers your question.
