Is there risk for infection in the replaced aortic valve?

Is there risk for infection in the replaced aortic valve?

Yes: Any time there is bacteria in our blood stream, it can infect a heart valve. If a heart valve doesn't work properly (leaks too much or doesn't open enough) that risk increases as does if there is an artificial valve. The best way to prevent this is to see your dentist regularly to make sure your teeth and gums are healthy and to see your doctor immediately for any infection or persistent fever. ...Read more

Valve (Definition)

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

Why do homograft aortic valve replacements have a low risk of infection?

Why do homograft aortic valve replacements have a low risk of infection?

Not quite true: Homografts in any position may have low to intermediate risk of infection but it is higher than the native valve. Still antibiotic prophylaxis prior to dental, Gyn and GU procedures is reccommended ...Read more

How come homograft aortic valve replacements have a lower risk of infection?

How come homograft aortic valve replacements have a lower risk of infection?

They don't: There have been studies looking at re-infection risk after aortic valve were replaced in the treatment of heart valve infection. The choice of a homograft vs other options did not influence outcomes. We use to think it would, but it does not. ...Read more

That : That is a lot for someone to go through and it is remarkable that he survived such a severe infection! there are a number of things that can happen, the least likely of which is a piece of valve ending up in the hand. With severe endocarditis (infection in the heart), clots and clumps of bacteria can be thrown from the heart into the major vessels. From there the vessels get smaller and smaller and pieces can lodge in any of these. Some of them will dissolve and others can create scars or secondary infections. Depending on the valve used, it may be more or less fragile. Metal valves are unlikely to have particles break off, but i suppose it would be possible for a pig or cow valve to have a fragment. However, this is still very unlikely and it is more likely that a clump of bacteria, called a vegetation, escaped from the heart. Also, is the nodule even related to the endocarditis? There are any number of small nodules that occur in the hand. If this is causing symptoms, such as pain or numbness, or is increasing in size, it may need to be removed. It is best to have it looked at by a hand surgeon. ...Read more

Many reasons: There are lots of possible reasons for dyspnea after aortic valve replacement surgery. Physical deconditioning ("out of shape") would be common. Some other reasons might be lung disease, pericardial constriction, pleural effusion, patient-prosthesis mismatch, or paravalvular prosthetic leak. ...Read more

Aortic Valve (Definition)

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

Infection (Definition)

Infections are invasions of some other organism (fungus, bacteria, parasite) or viruses into places where they do not belong. For instance, we have normal gut bacteria that live within us without causing problems; however, when those penetrate the bowel wall and enter the bloodstream, ...Read more
