[Consumption coagulopathy found in mitral stenosis associated with atrial thrombus].

Two cases of consumption coagulopathy found in the patients having mitral stenosis with atrial thrombus were reported. In case 1, although anticoagulant (Warfarin) administration did not correct the hemostatic abnormality, combination of tranexamic acid with anticoagulant was effective. In case 2, atrial thrombus found in the echocardiography prior to the onset of thromboembolism in the lower limbs has been disappeared after embolism. Anticoagulant was effective for the improvement of hemostatic abnormality. We considered mitral stenosis with atrial thrombus as one of causes of the consumption coagulopathy.
