Is There A Major Difference Between Cow And Pig Heart Valves For Replacement
Not really: Both offer the advantage of not requiring "blood thinning" on a long term basis. Unlike a "mechanical" valve, cow and pig don't last longer than 7-12 years(with a few exceptions). Otherwise, the outcomes in both valves are generally the same and for all intents and purposes, either one is a reasonable choice in a patient who does not desire blood thinning. ...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
Tissue valves: The size of pig and cow valves approximates the size of human valves. They are chemically treated to decrease the likelihood of tissue rejection. The porcine valves are more commonly used than the bovine. ...Read more
Tissue valves: We use beef, pig and human aortic valves as replacements in humans. Those three most closely simulate the size of the human valves. ...Read more
Why is it that the human body does not reject bovine or pig heart valves. Can cells from different animals survive in humans?
Medical technology: The valves are derived from pig or bovine but are treated in a laboratory to remove the antigens that would cause a reaction against them in a human body. Medical technology is amazing! ...Read more
Mitral valve: Outcomes with mitral valve replacement are not quite as good as aortic valve replacement but, in many cases, the mitral valve can be repaired which is always preferable to replacement and has excellent outcomes if it's an option. The tricuspid and pulmonic valves are lower risk and less frequently needed operations. ...Read more
Valve infection: Fungal infection of the valve — serious and debilitating. You would have to have an abnormal valve, infection of the blood stream (bactaremia) and/or be immunocompromised. Blood cultures can detect candida in the blood. If positive, the next step would be imaging tests of the heart valves. ...Read more
Depends: Trace to mild amount of leakage is considered normal in right heart valves. It is not uncommon to see trace amount of leakage on the left side in normal individuals. Leakage of the valves is also somewhat dynamic depending on pressures, can be seen at times but not all the time. ...Read more
Numerous: An infection of the heart valves, known as endocarditis, is a very serious disorder. Symptoms usually stem from infection in the blood stream and include fever, chills, possible low blood pressure or even shock, heart failure, shortness of breath, and may include severe damage to the infected valve causing severe leakage of the valve, requiring emergency valve replacement surgery. ...Read more
Endocarditis: When a bacteria gets in the bloodstream, there is a chance of attaching to a heart valve. This is called endocarditis. If this happens, the bacteria can grow, causing lesions called vegetations to appear which can break off and plug small blood vessels in the hand, foot, or brain. The bacterial growth can also cause the valve to leak. If this is significant, valve replacement may be needed. ...Read more
Nope: Sorry- we haven't found any substances yet that can reverse that process. Statins looked promising at one point but a couple of key trials ended up being negative. That said, at 21 you shouldn't have thick heart vavlves. Consider an evaluation for rheumatic fever and certain drug effects if you do. ...Read more
Heart valves: It is difficult to answer this question and it depends on your symptoms. If your symptoms are minimal the you can safely wait, however if you are suffering debilitating symptoms then you need the repair done as soon as possible ...Read more

Can you explain how the heart valves opening/closing is synchronized with the heart's pacemaker firing?
One causes the other: The pacemaker of the heart initiates an electrical impulse that spreads across the upper chambers and causes them to contract. Contraction of the atria pushes the atrioventricular valves open. Subsequently, the electrical impulse is transmitted to the lower chambers of the heart. The contraction of the ventricles opens the semilunar valves; at the same time the atrioventricular valves close. ...Read more
How long after a cardiograph will it be for my heart opereation? A bypass and two heart valves replaced plz
Don't understand: I don't understand your question. Please clarify. Are you having a procedure? Is it for a repeat open-heart surgery. You need to ask your doctor who is taking care of you to explain all the things he or she wants you to have ...Read more
Dr. Says i have trace regurgitation in 3 heart valves. Only recommending yearly echos to check on it. Is this normal im otherwise healthy?
Just a trace.: Trace regurgitation is usually nothing of immediate concern — it wouldn't cause any symptoms and may just be reflective of the way your valves open and close normally and thereby may never progress beyond trace. Yearly 2D echo is recommended to make sure trace regurgitation doesn't become mild, then moderate and then severe, but this doesn't always happen. ...Read more
I feel a tingling sensation in my left upper thigh. Also, at times it heats up where I can t stand it. I m 63 and have 3 heart valves not working right?
Sounds like you: Have irritated you lateral femoral cutaneous nerve. Causes a syndrome known as meralgia parasthetica. The nerve can get irritated by wearing a tight belt as it gets pinched at your waistline, a big belly that puts pressure on it or sitting forward for long periods of time. Nsaids, steroids, removing the irritating factors can help. If you have heart issues, see your doc before taking meds. ...Read more
APS affects balance, "brain fog" twitching muscles. Cardio dr said has affected my heart valves as well. Is this uncommon? Any recommendations?
Yes : 37y fem. w. autonomic parasympathetic system disorder w. "Twitching muscles, dis-coordination & brain-fog". Women w. Fibromyalgia, FM, experience same symptoms. Cardiologist says "heart valve" problem. Mitral valve prolapse /FM via inherited Hypermobility Syndrome. Echocardiogram easily defines MVP. FM cured w. aquatherapy, wt. loss, cannabis for depression mood & sleep, biofeedback, mindfullness. ...Read more
Analyse risk/benefit: Artificial heart valves came on the medical scene in 1961. Prior to these life savers, open-heart surgeons could repair damaged heart valves. A valve repair might last 1 to 6 years. The question you need answered is... Without a heart valve how will my health be? From that point you can get the risk of implanting and maintaining your new valve. Take a friend/family with you to help decide. ...Read more

Three leaky heart valves and palpations. Was prescribed no meds. Was told heart was healthy can this be true?
Before echo's: In the old days, rheumatic heart disease was the cause of most "hearable" murmurs:if heard, you were in trouble. Now with better stethoscopes & esp echo machines, "innocent" murmurs are frequently heard (or small valve leaks are commonly seen with echo) and normal--even all four valves. www.thepmc.org. ...Read more
