If the patient shows signs of mitral stenosis, it could be due to congestive heart failure causing pulmonary congestion, which may lead to blood-streaked sputum. It is also possible that the bleeding is caused by vascular dilation. For bleeding caused by mitral valve issues, symptomatic treatment is primarily used. Medications to stop bleeding can be employed, as well as vasoconstrictors to achieve hemostasis. However, it is still recommended that the patient visit a hospital to undergo cardiac echocardiography and chest CT to further confirm the diagnosis and determine the treatment plan. Currently, medications that improve myocardial function or reduce cardiac load can be used for treatment.
