(Prosthetic Valve Thrombosis; PVT)



Prosthetic heart valve thrombosis is a rare but serious complication of a heart valve replacement procedure . The complication occurs when a blood clot called a thrombus is attached to or near a prosthetic heart valve. This can obstruct blood flow or interfere with the function of the valve. This condition can be life-threatening. Seek medical attention right away if you think you have prosthetic heart valve thrombosis.
