How long does a coronary artery bypass graft procedure take?

Approximately how long would a bypass operation take? Yeah, I mean, the average duration of a bypass operation can vary somewhere between three to three and a half hours. Obviously, the duration of the operation also depends on the expertise and experience of the surgeon forming the procedure and what sort of operation you are performing. An average standard bypass operation, which for a layperson is known as a triple bypass operation, would generally take around three to three and a half hours.
