Roy, age 25: I was born with a bicuspid aortic valve. The valve has two leaflets instead of the three it's supposed to have. I'm going to have a mechanical valve, mainly because of my age—I'm only 25, so I know that if I have a tissue valve, I'll have to have it replaced at least once, and probably twice. My doctor says that tissue valves also can become hardened in younger people.

Rhonda, age 72: When I found out that I had a narrowed aortic valve, I talked with my doctor about what type of valve I should have. We agreed that because I'm 72, a tissue valve would be fine. They last for 10 to 15 years, and sometimes as long as 20. Besides, I won't have to take anticoagulants every day for the rest of my life.

Chantal, age 51: I take anticoagulants for another heart condition. My doctor said that because I take this medicine anyway, I should consider having a mechanical valve because it will last longer than a tissue valve.

Maurice, age 57: I decided to have a tissue replacement valve because I have a history of bleeding stomach ulcers. If I get a mechanical valve, I will need to take anticoagulants every day, and they can increase the risk of bleeding. So a tissue valve is a better option for me.
