Valvular Heart Disease refers to conditions that affect the valves of the heart, which are crucial for regulating blood flow. The heart has four valves: the mitral, tricuspid, aortic, and pulmonary valves. When these valves do not open or close properly, it can lead to problems such as stenosis (narrowing) or regurgitation (leakage), affecting the heart's efficiency. Symptoms of Valvular Heart Disease can include shortness of breath, fatigue, and swelling in the legs or abdomen. Diagnosis typically involves echocardiograms and other imaging tests. Treatment options may range from medication to surgical interventions, depending on the severity of the condition.
