Mitral valve replacement is a procedure in which the diseased mitral valve of a patient's heart is replaced with either a mechanical valve or a tissue, or bioprosthetic, valve. The valve may need to be replaced because it has become leaky, a condition called mitral valve regurgitation, or narrowed so that it no longer opens properly, a condition called mitral valve stenosis, with causes of mitral valve disease including infection, calcification and inherited collagen disease. Current approaches to mitral valve replacement include traditional open heart surgery and minimally invasive cardiac surgery.

FAQs
How do mechanical and tissue valves differ in mitral valve replacement?
The National Heart, Lung, and Blood Institute says tissue valves need no blood thinners but may have to be replaced, while mechanical valves last longer but require blood-thinning medicines for life.
Mitral valve replacement uses either a mechanical valve or a tissue, also called bioprosthetic, valve. The US National Heart, Lung, and Blood Institute, describing heart valve replacement in general, says biological valves, also called tissue valves, are made from animal tissue and may have man-made parts as well. It says tissue valves do not require blood thinners but do not last as long and may have to be replaced. Mechanical valves, it says, are made from carbon or other sturdy material, last longer than biological valves and usually do not have to be replaced, but require blood-thinning medicines for the rest of a person's life.
