Your doctor replaces your valve with an artificial valve made of plastic or metal. When the fluid moves to the right blood gets pumped to the lungs through an artificial ventricle.
Mechanical Heart Valves And Blood Thinners Are There Natural Alternatives

How does a mechanical heart valve work. Biological valves are made of human or animal tissue cow and pig hearts are often used and usually have a shorter life span than mechanical valves. What is a mechanical heart valve. A bio heart valve or mechanical heart valve may be the best option to repair a damaged heart.
1 if the heart valve cannot be repaired a decision must be made as to what type replacement valve should be used. When the fluid moves to the left blood gets pumped to the rest of the body. Valve replacement or repair is the definitive treatment in those with severe valvular heart disease.
What is a mechanical heart valve. A mechanical heart valve is made from materials that do not include any form of biological tissue pig cow horse. Instead very strong materials such as titanium and carbon are used in a mechanical heart valve that make them incredibly strong and durable.
While mechanical heart valves provide excellent durability one of their main disadvantages is the persistent risk of thrombosis which can lead to valvular dysfunction 35 36 the most common cause of valvular dysfunction results from obstruction of the valve discs by thrombus and to a lesser extent the formation of pannus 36 pannus formation is characterized by fibrous tissue ingrowth and. A heart valve may be replaced when it is damaged or narrowed by disease. The use of mechanical valves in the pulmonary position is relatively rare but these valves are occasionally used to treat adult and congenital disease.
Mechanical valves however require the patient to take anti coagulant medication continually to prevent blood clots source. Porting valve this valve opens and closes to let the hydraulic fluid flow from one side of the artificial heart to the other. When heart valve disease progresses to the point that treatment by medicine does not provide relief from symptoms a physician may recommend surgery to repair or replace the valve.
The choice of valve depends on valve durability the need for antithrombotic therapy and patient preferences 1 2 mechanical heart valves are preferred in patients under 65 3 bioprosthetic valves do not require lifelong anticoagulation but have a greater rate of primary. The new valve controls the normal flow of blood into and out of the heart. Typically the choice is between a carbon based mechanical valve and a tissue valve.
Artificial heart valves can be biological or mechanical. A leaking heart valve not only puts additional strain on the hardest working muscle in your body it can lead to aneurism or separation and further damage to your heart. Although a bioprosthetic valve is preferred in this position mechanical pulmonary valves have been implanted in patients who are already.
