Aortic Valve Tissue Vs Mechanical
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. ...Read more
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more
May be decades: mechanical valves are the most durable of all heart valves. The "biological valves" or "tissue valves" usually last a decade or so but have the advantage or lower risk of clotting and less need for anticoagulation. Patients with mechanical valves general should be anticoagulated with Coumadin (warfarin). People who have a long life span and have low risk with anticoagulation are best for mechanical valves ...Read more
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. ...Read moreSee 2 more doctor answers
Check with your doc: If you have your aortic valve replaced with a tissue valve, some surgeons do not recommend warfarin at all, others may suggest you take a blood thinner for a short while e.g. 1-3 months. If you have any other problems such as an irregular heart beat like atrial fibrillation, you may have other reasons that you would need warfarin. It would be best to check with your doctor. ...Read more
What is best method for replacing aortic valve damaged due to rheumatic heart disease for 51 year old man?mechanical biological or auto or homograft?
Longevity: Repair is the best option but may not be feasible. The tissue valve options are attractive because of minimal anti coagulation but at 51 you would have to plan on at least one reoperation in the future. Mechanical should last a lifetime but will require anti coagulation that may inhibit some of your activities. Discuss in depth with surgeon and cardiologist. ...Read moreSee 2 more doctor answers
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?
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. ...Read moreSee 1 more doctor answer
My husband had open heart surgery at 57 for a mitrial valve repair. At 66 he needs his aortic valve replaced He is in excellent health. Can he have a third operation when that tissue valve wears out?
Sure: The suggestion would be to cross the bridge when you get there. Since he's in good health he probably won't need any more surgeries... There are other minimally invasive valve procedures being developed... So when the time comes for third - he may be a candidate for that. ...Read moreSee 1 more doctor answer
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?
Between LV and Ao: The aortic valve is a passive flap valve with three leaflets which opens as the left ventricle (LV) ejects blood into the Aorta (Ao). After ejection, the LV relaxes, and when LV pressure is lower than Ao pressure, the aortic valve flaps closed, preventing blood from leaking (regurgitating) back into the heart. ...Read moreSee 3 more doctor answers
Aortic Valve: The aortic valve functions as a valve -no surprise here-. So it can either leak or be restricted (stenotic). Both conditions, when severe, need to be corrected. This is usual done by replacing the defective valve with an artificial one. There are many conditions/diseases that can cause the valve to leak or be restricted. ...Read moreSee 1 more doctor answer
Aortic Valve: The aortic valve is an integral part of the heart and is located between the left ventricle and the aorta. It opens when the left ventricle contracts (systole) and allows blood to be pumped into the aorta. It closes when the left ventricle fills (diastole). ...Read moreSee 1 more doctor answer

It's function is to prevent blood from flowing back from the aorta while the heart is filling. ...Read moreSee 1 more doctor answer
The aortic valve is one of 4 valves in the heart, each of which separates 2 cardiac chambers. It opens when blood is actively ejected from the left ventricle into the aorta artery, to be carried to the rest of the body. It then closes firmly to prevent blood from flowing backwards, while it passively continues to flow forward to body's vital organs. When next heartbeat ...Read more
The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more
