If you need to have a heart valve replaced, you\u2019re probably wondering about your options.\nBoth mechanical and tissue valves offer different benefits and risks, so it\u2019s important to talk with your doctor about the best option for you.\u00a0Learn more about the types of heart valves, their pros and cons, and what questions to ask your doctor.\nRELATED:\u00a0Which Heart Surgery Is Best?\nHow Do Heart Valves Work?\nYour heart has four valves that open and close to allow blood to flow into, through, and out of your heart. Your valves include:\n\nThe tricuspid valve. When blood flows back into your heart from your body, it passes from the top right chamber through the tricuspid valve to the bottom right chamber.\nThe pulmonary valve. Once blood enters the bottom right chamber, it flows through the pulmonary valve to your lungs to pick up oxygen.\nThe mitral valve. After blood picks up oxygen in your lungs, it flows into the top left chamber of your heart and passes through your mitral valve to the bottom left chamber.\nThe aortic valve. From the bottom left chamber, blood gets pumped through your aortic valve into your aorta and out into your body.\n\nYour valves have flaps, called leaflets, that need to open fully and close tightly to keep blood flowing forward, in the right direction. If a valve becomes narrow, it may not open widely enough to allow enough blood to flow. If it becomes weak or damaged, it may allow blood to leak backward.\nWhat Causes Heart Valve Damage?\nA heart valve can stop working properly because of many conditions, including:\n\nCongenital heart defects, or heart problems you\u2019re born with\nEndocarditis, an infection in the heart\u2019s chambers or valves\nAortic stenosis, which happens when the aortic valve becomes narrow, usually because of calcium buildup\nMitral valve stenosis, which happens when the mitral valve becomes narrow, usually because of calcium buildup or as a result of rheumatic fever or scarlet fever in childhood\nMitral valve regurgitation, which happens when the leaflets cannot close properly, usually because of extra tissue\n\nRELATED:\u00a0Aortic and Mitral Valve Disease Treatment Options\nTypes of Replacement Heart Valves\nThere are two types of replacement heart valves: mechanical valves and tissue valves. Both have pros and cons, depending on your specific needs.\nA mechanical heart valve is made of long-lasting materials like metal or ceramic and can usually last a person\u2019s lifetime. To prevent blood clots from forming and blocking the valve flaps, patients with mechanical heart valves need to take blood thinner medicines for the rest of their lives. Mechanical valves can be good options for younger people who can safely take blood thinners.\nA tissue heart valve is made of biological tissue, usually from an animal, and can last about 10 to 20 years. While tissue valves are not as long-lasting as mechanical valves, they do not usually require long-term use of blood thinner medicines. Tissue valves can be good options for people who are older, or people who cannot safely take blood thinner medicines.\nWhat\u2019s Right for Me?\nTo figure out what is best for you, your doctor will take many facts into consideration, such as\u00a0your age, overall health, and specific type of heart valve disease. When talking with your doctor, be sure to ask these questions.\n\nWhat are my options for treatment?\nIs a mechanical valve or tissue valve better for me?\nWill I need to take blood thinner medicines after my surgery?\nHow many of these procedures have you done before?\nHow long will I need to stay in the hospital after my surgery?\nWhen can I return to my normal activities?\nIs a cardiac rehabilitation program right for me?\n\nTo learn more about heart valve replacement, visit the UPMC Heart and Vascular Institute or call 1-855-UPMC-HVI (876-2484).
