Question: You are managing the care of a 65-year-old patient who has been diagnosed with mitral stenosis. The patient is unsure why she needs to be on warfarin therapy. Propose what you would include in your explanation to this patient. Much regurgitation is often associated with protein deficiencies needed for coagulation. There is an increased risk of clot formation. Ventricular arrhythmia is possible. Stasis of blood in the vasculature promotes coagulation.
