Funny you should say that MM, there are videos on the net showing the operation and I studied them beforehand. If anyone wants to know more the Cleveland Clinic and the Mayo Clinic are the world leading heart specialists and have good info on their sites.
Anyway, open heart surgery is not a cakewalk. I may have appeared cheerful and no worries but underneath I was exceedingly nervous. So I fronted the surgeon. I pointed out to him that he proposed to crack my sternum, then crank it wide open with retractors which you can imagine comes as a bit of a shock to the ribs. After that he'd plunge his hands into my chest shoving aside the lungs and anything else in the way and grab my heart, at which point I was a dead man.
Not only that but the aeorta and vena cava would then be pierced so the perfusionist could artificially run my blood supply, while the anaethesist kept the body as close to death as he could manage. And to top it off the body would be cooled to slow metabolism down. The butcher....er surgeon then intended to cut my heart open, fiddle about with the mitral valve, cut pieces out of it, or if things were in a parlous state, replace it with a mechanical valve. After which he'd have a scotch, put in a few stitches, run some lacing wire through the sternum, hook me up to an electric fence and Voila - the Tui Moment - back to life.
Yeah right.....
He just grinned at me and said restarting the heart was the least of my worries. As it turned out, he was right.
