Due to mitral stenosis, thrombus formation can sometimes occur, especially when ischemic cerebrovascular diseases lead to cerebral infarction. This is because mitral stenosis can cause emboli to dislodge and travel through the bloodstream to reach the cerebral arteries or veins, leading to thrombus formation. During this period, anticoagulant medications are sometimes used for treatment. If a patient has a history of mitral stenosis, it is necessary to actively use medications for treatment. During this time, it is also important to monitor changes in the patient’s heart rate, blood pressure, and pulse to control the ventricular rate. Currently, treatment is primarily symptomatic, aimed at improving cardiac function.
