Mitral valve insufficiency can lead to left heart failure, as it may cause excessive pressure in the left atrium and ventricle, leading to left heart failure. This condition is characterized by symptoms such as coughing up pink frothy sputum, feeling of heart palpitations, chest tightness, and difficulty breathing.

This situation leads to an increased afterload on the heart, causing a series of symptoms. Therefore, mitral valve insufficiency can result in left heart failure, especially noticeable during the night with orthopnea and coughing up pink frothy sputum, which are typical clinical manifestations of left heart failure. The current treatment primarily focuses on symptomatic management, using medications such as cardiac glycosides and diuretics to improve symptoms.
