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

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

Depending upon the degree they were compromised with the old/damaged heart, they will be rejuvenated by the new heart. Most of the old heart is removed, so that there is little to 'mend.'. ...Read more
