Severe mitral valve regurgitation requires surgical treatment, with options including mitral valve repair or replacement surgery. If left untreated, severe mitral regurgitation can lead to enlargement of the left ventricle and a reduction in the heart's ejection fraction, resulting in decreased pumping function and symptoms of heart failure. Patients may experience symptoms such as difficulty breathing, fatigue, and nocturnal paroxysmal dyspnea. Severe cases might even exhibit symptoms of acute left heart failure, such as orthopnea, profuse sweating, and coughing up pink frothy sputum. These symptoms typically necessitate hospitalization, which not only adds unnecessary financial burdens but also severely impacts the patient’s quality of life.
