What are the important prosthetic valve emergencies?

While most of the native valve emergencies are due regurgitations, prosthetic valve emergencies can be due to regurgitations or stenosis. Most common prosthetic valve emergency is due to prosthetic valve thrombosis in a mechanical prosthetic valve. This can cause acute stenosis, regurgitation, or both. Prosthetic valve thrombosis and thromboembolism are most likely during the first three months after the surgery for implantation of the valve. This is the period during which the valve gets endothelialized, after which risk of thrombosis is lesser. Thrombotic complications can be minimized to a large extent by meticulous anticoagulation management.
