I chose the tissue valve because of the coumadin issue, my dad took it for years and I know how much trouble he had with it.
You need to know that before 1992?, anti-coagulation was monitored by measuring the Prothombin (clotting) Time.
The problem with that method is that they have determined that there was a WIDE Variation in the measurement based on differences in the Chemical Reagent that was used.
In 1992? a Greatly Improved method of monitoring was introduced. It is called the International Normalized Ratio (INR) and it compares the Ratio of clotting times for your blood and a known sample. By taking the Ratio of those times, the variation in Reagent factors is cancelled out.
Dedicated Anti-Coagulation Clinics and Home Testing have greatly improved results. There is a wide variation in Quality of Management by independent Doctors and Nurses, especially those who were trained before INR testing became the norm. Unfortunately, there is also a lot of misunderstanding and Outdated Information still in the minds of many 'older' practicioneers. Home Testing has proven to give the BEST results. Several companies now produce small 'finger stick' machines that are similar in operation to the ones used by dibetics.
Please look at the 'tickys' at the top of the Anti-Coagulation Forum listing and at AL Lodwick's excellent website
www.warfarinfo.com for CURRENT information on living with / on anti-coagulation.
Out of curiosity, which type of Tissue Valve did you select?
The Bovine Pericardial Tissue Valves have a proven longevity approaching 20 years (when implanted in patients aged 60 or over). The new and improved versions have an 'anti-calcification' coating that is hoped to extend that lifetime a few more years.
There are several different types of Porcine Tissue Valves. Some of them are known to have Lower Gradients which is useful to Athletic Types who want to push themselves to the max. Some of them also have treatments to hopefully extend their durability. Untreated Porcine Tissue Valves (straight from the pig) typically last only 8 to 12 years in older patients. The New and Improved Porcine Valves haven't been out long enough to know how long they will last.

I'm glad you had a chest CT. That should have given the examining Doctor a good view of your aorta. Some pictures of Aortas with aneurisms have been posted in the BAV and CTD Forum. To the best of my knowledge, the TEE gives a good view of the Heart Valves but I can't imagine it giving a good view of the Aorta, especially the Aortic Arch.
