Valvular disorders are conditions that affect the heart valves, which are crucial for regulating blood flow within the heart. These disorders can lead to problems such as stenosis, where a valve becomes narrowed, or regurgitation, where a valve does not close properly, allowing blood to flow backward. Commonly affected valves include the mitral and aortic valves. Symptoms of valvular disorders may include shortness of breath, fatigue, and heart palpitations. Diagnosis typically involves echocardiograms and other imaging techniques to assess valve function. Treatment options can range from medication to surgical interventions, depending on the severity of the condition.
