I actually enjoyed it. The Doc seemed very nonchalant about the whole thing, I thought they would be a little more gentle.
I know the cardiothoracic surgeon that performed the procedure (a great guy, very friendly and is one of the top surgeons in the world). He usually operates on Mondays, Wednesdays and Fridays, with Tuesdays and Thursdays being for consultations, although often times he has to perform emergency operations on those days as well, as well as weekends. He also does the rounds at the wards on weekends.
On one typical day, he may perform up to 4-5 surgeries, depending on the type of procedure, and is usually on his feet from 7am till 9pm (all-nighters are not uncommon.) If it's a standard heart bypass or valve repair, such an op would take around 3.5 hours - assuming no complications - from the time they gas the patient to closing up the patient. Heart transplants and LVAD implantations take longer - in fact, when a donor heart becomes available, it becomes priority and other scheduled surgeries are postponed to accomodate this.
So, in a typical week, the surgeon may perform around 12 - 18 heart surgeries. The surgery he performed on Saturday was very much a routine one, and when you've performed the same type of surgery for years, you become comfortable and relaxed about it (like any other skilled job). Many people think that an operating theatre is a serious and quiet affair. Serious, yes (the patient's life is in the surgeon's hands), but quiet? not always... the surgical and theatre staff chat, discuss current events, swap jokes, with conversation becoming quiet during a particularly complicated procedure.
I've attended several open heart surgery procedures and it's absolutely fascinating. The broadcast on TV gives you a good impression of what happens, but nothing beats standing next to the patient and watching the whole thing happen from start to end. If you have an opportunity to observe open heart surgery in person, go grab it!
BTW, the surgeon couldn't pull off the surgery without the anaesthesiologist, the perfusionist, the scrub nurse... it's very much a team effort!
