AVR. Aortic valves can be replaced with either mechanical valves or bio prosthetic, taken from animals and treated to prevent rejection. There are different reasons for choosing either valve such as age and treatment with anticoagulants. Individuals who do not wish to be on meds such as Coumadin (warfarin) may have a bioprosthetic valve, however, younger individuals usually have mechanical valves.
Depends. Age bleeding risks ulcers, diverticulitis etc travel compliance with medicines we offer all choices and tailor to the specific patient scenario. The mechanical valve patients are treated for life with anticoagulants.
Why will my tissue aortic valve replacement only last for 7-12 years, especially because my original lasted 65 years?
Foreign material. A tissue (pig or cow) or "bioprosthetic" (synthesized from natural tissue such as pericardium) generally lasts 7-12 years (with some variability) because, unlike your native valve, is foreign to the body. It is susceptible to certain stresses that your own valve wasn't. They are safe, however, and improve the quality of life during those years.
Which type of tissue. If your original lasted 65years you should be older than 40years old. Need to clarify.
It's not alive. The tissue valves we implant are made of treated tissue from either a pig or cow. They are not living tissue any more. So over time they begin to wear out. On the other hand you original valve is alive and can repair itself to some effect.
Artificial vs tissue aortic valve replacement. Is it worth it to do tissue when it will have to be redone in 10 to 12 years? Effects of blood thinner?
Discuss with MD. You really need to discuss this with your surgeon. It is way too involved of a discussion for this kind of board.
Depends..... Depends on age, lifestyle and need or not for anticoagulant for other reasons. Coumadin (warfarin) is not without risk, while the risk for re-replacement of a tissue aortic valve is not high. So if you are relatively young (<60), don't need Coumadin (warfarin) or don't want to take it, it would be very reasonable to have a tissue valve with the understanding that you will probably require another replacement.
Had mechanical aortic valve replacement on 2001. Been on warfarin ever since want to get a tattoo on the inside of my forearm. Is this save?
Maybe. A tattoo is only skin deep shouldnt be a high risk for bleeding. You may ooze and bruise but a life threating bleed very unlikely. Infections can occur and with a mechanical aortic valve, endocarditis is a remote but catastrophic complication. I personally would not go looking for trouble. Antibiotic prophylaxsis may help but chk with your docs.
Not really. You may not bleed much, but I worry about technique and infection and valve infection is a disaster. You are a lucky beneficiary of american ingenuity and medical care! Why take a elective risk?
Reasonably safe. Generally aortic valve replacement is a reasonably safe procedure. The operative risks however depends on the overall condition of the heart, age, presence or absence of other problems such as lung and kidney disease and the overall physical strength of the patient. In most cases the surgical risk should be less than 5% chance of a bad outcome.
