How long does heart surgery take to complete?

I'm writing a screenplay and I want to make it as believeable as possible, so if you know the answer, please share.

Here's the situation:
The character was vacationing in California, had a heart attack and had to get heart bypass surgery. How long would it take for the character to have the surgery and recover. And how long would he have to be in the hospital for.
Thanks guys!

1. A routine bypass operation takes approximately four hours.

2. The hospital stay for a routine bypass operation is 3-5 days. If off pump is used most people are discharged on average 3/2 days postoperatively. Usually 5 days for traditional bypass.

3. Recovery time: 4-6 weeks if all goes well, It usually takes 4-6 weeks for the breast bone and chest muscles to heal, and patients gradually return to their usual daily routine.

I had bypass operation and my mitral valve replaced. The mitral valve replacement surgery lasted about 6-7 hours total. The bypass operation lasted about 4 hours.

First he would have to have a heart catheterization to determine his blockage, where it is, etc.
Then they can do the surgery either on bypass or off bypass.
If they do it on bypass, the heart and lungs will basically be turned off inside of the body, and run through a machine.
If they do it off bypass, the anesthesologist, will slow the heart rate, way down by the use of IV medications.
While the heart surgeon is opening the chest, there is another surgeon opening the leg to get the saphenous vein out of the leg. This vein is used for the bypass.
Then, the surgeon begins bypassing the blockages. He ties the vein onto the heart, and then bypasses the blocakage.
While that is taking place the other surgeon is placing a graft into the leg, where the vein came from.
After the surgeon is completed with his bypasses, then the person is brought back off the bypass machine.
They restart the heart and lungs.
The surgeon then closes the rib cage, and the chest.
After this is completed the patient is awakened and taken to CCU
The length os the surgery varies. I have seen it completed in 2 hours, other times many hours. The longest one I have seen began at 1:00 pm, and didnt end until 4:00 am the next morning, when the patient died on the table

two weeks
