Monty,
Welcome to the VR site! This is a good place to vent dissatisfaction, frustration, confusion, and even elation regarding valve replacement surgery.
First off, I'm with Nancy on the surgeon's lateness. They do get held up. However, if you're not a match with your surgeon for other reasons, you should consider seeking another. If you're already at CCF, you've hit the mother lode.
I also agree with Al that if you're looking at valves, you should consider all the types, unless you have already ruled out mechanicals because of the required anticoagulation. At 47, you're young enough that it deserves consideration at some level. There are many enthusiastic marathon runners on this site who have mechanical valves, and a famous one or two. A peek at some of the threads in the Active Lifestyles forum should find them quickly.
As far as tissue products, here's my biased take on your issue: The St. Jude Toronto valve was approved by the FDA in 1997, and is an unstented valve. The Toronto valve uses a different implantation technique than other aortic valves, and the surgeon you have may have specialized in that technique, thus making it his preferred valve.
A stent is a fixed ring at the base of the replacement valve, to hold its shape. Unstented valves are shaped by the place into which they are implanted.
Unstented valves can have an advantage in bloodflow over a standard mount valve. The Carpentier-Edwards Perimount Magna overcomes this by its superior placement in implantation, allowing a larger opening as the stent is not in the line of blood flow ("superior" meaning "on top of" in this case). The Mosaic's response is that it uses a stent that is thinner by half than other stented valves, allowing more flow in a traditional placement.
Here's a link to some info on the Toronto valve:

The Toronto valve does not indicate that it has the newer anticalcification features found on the Mosaic or CEPM. Its history in the US is relatively short, and the studies it refers to are very short-term and mostly over five years old. Also, the numbers from their "patient recovery" graphs stretch reasonable limits. As examples:
- Average ICU time for unstented valves - 26.4 hours, stented valve - 110.4 hours. Most people are expected to leave the ICU the next day with any valve type. I was home in 75 hours (with my stented valve).
- Average hospital stay for unstented valves - 9.7 days; stented valve - 14.2 days. Most people are expected to stay 5-7 days for all valve types in the US. Three days for the lucky.
- Average ventilation time with unstented valve 16 hours; unstented 55 hours. Most people are now off the ventilator later the same day with all valve types, usually in less than 12 hours.
Of course Ross, Harpoon, and a few others had to go and mess up all those quick ICU, ventilation, and hospital stay times for everybody...
So, the graphs in the St. Jude description/marketing site don't cut it with me, as the numbers (to me) clearly do not reflect current practices. I am not aware of any difference in ventilator, ICU, or hospital stay time accorded to patients at this time, based only on the brand of the valve or whether the valve is stented. You could ask the surgeon's people whether that practice exists at CCF.
This doesn't mean the Toronto is not a good valve, or even a great valve. It has been in the US for seven years, and its competition has been there much longer. And the track records of the Magna and CEPM predecessors are excellent. Although St. Jude is a very large name in heart valves, and is by far the largest supplier of mechanical heart valves, use of the Toronto valve still lags behind the use of Medtronics and Edwards Lifesciences tissue valves.
The Mosaic and CEPM also have extra anti-calcification features which could reasonably be beneficial to a young tissue recipient like yourself, as younger valvers seem to calcify their valves more rapidly.
This is not a vote against the Toronto, but it is one for looking at the other offerings as well.
This here is a link to a post that has links to tissue valve sites (sounds convoluted, but really isn't):

I know you're in kind of a hurry. Hope this helps you find more to chew on.
Best wishes,
