Mechanical Aortic Valve Replacement
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

I would like to take green coffee bean supplements for weight loss. I am taking Coumadin after a mechanical aortic valve replacement surgery 9 years a?
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 may have a bioprosthetic valve, however, younger individuals usually have mechanical valves. ...Read more
Not proven (yet): Minimally-invasive heart surgery, including for aortic valve replacement, has not been proven to reduce postoperative complications in randomized studies of both approaches. The one important exception is postoperative pain and immobility; the minimally-invasive approach allows patients, on average, to be pain-free sooner, and become active and return to work, quicker. ...Read moreSee 2 more doctor answers
Keep reading...: You need preop angiogram to see if there's blocked coronary arteries that should be bypassed at the time of surgery, unless you're under 40 (50 for females) with no major risk factors. During surgery, heart is stopped from beating, while a machine ("pump") circulates blood through the body; this allows surgeon easy access. Postop recovery is usually 1 week in hospital, 2 weeks in cardiac rehab. ...Read moreSee 1 more doctor answer
Relatively safe: Heart surgery is major surgery with lots of potential complications but the good news is that for the vast majority of patients they are uncommon. A lot depends on how well your heart squeezes before surgery and your overall health. With good health and function infection 1%, stroke 1%, irregular heart beat 15-20% (often not serious), death 2% or less. Your surgeon is best resource. ...Read moreSee 1 more doctor answer
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
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
