Heart valve disease is a condition characterized by the malfunctioning of one or more of the heart's valves, which can impede the normal flow of blood through the heart chambers. The valves, including the aortic, mitral, tricuspid, and pulmonary valves, play a crucial role in ensuring unidirectional blood flow. Heart valve disease can result from congenital abnormalities, infections, age-related degeneration, or other acquired conditions. Common manifestations include valve stenosis (narrowing), regurgitation (leakage), or a combination of both. Individuals with heart valve disease may experience symptoms such as fatigue, shortness of breath, chest pain, and palpitations. Diagnosis involves imaging studies like echocardiography and may require further evaluation through cardiac catheterization or advanced imaging modalities. Treatment options vary depending on the severity and type of valve disease, ranging from medications to surgical interventions, such as valve repair or replacement, to restore proper cardiac function and improve the patient's quality of life.
