3. Mech Aortic Valve (On-X) in 2011.
I chose Mechanical for several reasons, but one factor that I haven't seen mentioned--family history-- My Grandfather and Uncle both have AVR--St. Jude mechical. My Grandfather had his 26 years with no futher issues before he passed at age 85. My Uncle is still going strong with no further issues for 12 years. So I figure my biology tolerates the mechanical valve and coumadin well.
