Heart valve replacement
Blood clots can form on a replacement heart valve. The clot can break off and cause a stroke or arterial embolus. Warfarin can prevent these clots. It is used for a short time after a tissue valve replacement but is required long term for people with metal valves. The warfarin treatment range varies depending on the type of valve.
Warfarin is sometimes used short-term after heart attacks and for the treatment of arterial clots and venous sinus clots affecting the brain.
