This heart valve disorder affects the heart valve known as the mitral valve. It is characterized by restricted blood flow due to the mitral valve not fully opening. Sometimes no symptoms occur. When they do, they may include cough, fatigue, heart palpitations, trouble breathing, frequent respiratory infections, swelling of feet or ankles, and in rare cases, chest discomfort.
In mild cases, no treatment may be necessary, but when severe, hospitalization may be necessary. Medications that may be used include antibiotics, diuretics, beta-blockers, ACE inhibitors, digoxin, anticoagulants, nitrates, calcium channel blockers and angiotensin receptor blockers. Some patients may require surgery, such as mitral valve replacement or repair.
