Well I saw the surgeon Dr McGiffin and got a date. I will check-in on March 17th and they will do heart cath and all the pre-op stuff and then surgery on March 18th at 2:00. they said they will do all the prepping early before he gets there. Now, I'm so happy to get it over with but I'm SO NERVOUS!!!! He said the valve has to be replaced because it is so calcified and leaking... I hate all these emotions right now, makes me feel like I'm crazy

but I know you all understand!!!! I need to let him know if I want the st judes or on-x valve. I'm going to do a little more research but pretty sure I want the on-x.
Here's a copy of a post I made on Jan. 7, 2009 in another Mechanical Valve 'discussion'.
Anti-coagulation does a pretty good job of preventing Clot Formation for most patients AS LONG AS their INR is in range.
For those times when it is necessary to go OFF anti-coagulation for other Invasive Procedures or Surgery, I would want the valve that is Least Likely to cause Clot formation and possible Stroke damage with NO anti-coagulation. Just MY opinion.
===================
A few years ago, On-X sent me an 'Information Package' which included a pair of tables entitled "Morbid Event Rates Comparison" for both the Aortic and Mitral positions with footnotes indicating the source of the data for each company which included PMA (something about Safety and Effectiveness) Summaries (ATS and CMI) and FDA submissions.
The combined rates in (% per pt-year) for Thromboembolism, Thrombosis, and Hemorrhage for the
Aortic Position were
On-X = 2.14 % per pt-year
SJM = 3.90 St. Jude Medical
CMI = 2.96 Carbomedics
ATS = 4.04 ATS
MH = 2.50 Medtronic Hall (I believe that is a single leaflet valve)
Mitral Position
On-X = 1.86 % per pt-year
SJM = 3.34
CMI = 4.44
ATS = 5.07
MH = 4.30
I left off the breakdowns by categories because I'm not about to sit here and re-type all that data. Note that other factors such as Hemolysis (blood cell damage) and Pannus Tissue Growth are not included in the above statistics.
The complete charts are available to ANYONE who asks for them. Just call or e-mail On-X and they will send you whatever information you request. Contact information is on their website
www.onxvalves.com or 888-339-8000.
They have recently published another set of Bar Graphs which also include several tissue valves (which I find a little hard to interpret - too much information in too little space... give me the numbers in a spread sheet format please).
