Valvular disease refers to conditions affecting the heart valves, crucial components responsible for maintaining the unidirectional flow of blood within the heart. The heart has four valves—mitral, aortic, tricuspid, and pulmonary—that open and close synchronously to facilitate efficient blood circulation. Valvular diseases can manifest as stenosis (narrowing) or regurgitation (leakage), both of which compromise the heart's ability to pump blood effectively. Causes may include congenital defects, infections, or age-related degeneration. Symptoms range from chest pain and fatigue to shortness of breath. Timely diagnosis through imaging studies and echocardiograms is crucial for appropriate management, which may involve medications, lifestyle changes, or, in severe cases, surgical intervention to repair or replace the affected valve. Effective management of valvular diseases is paramount for maintaining heart health and preventing complications.
