Aordiklappstenoos

Aordiklappstenoos refers to the narrowing of the aortic valve, a critical component of the heart responsible for regulating blood flow from the left ventricle to the aorta. This narrowing, medically termed stenosis, impedes the valve's ability to open fully, consequently restricting the amount of oxygenated blood that can be pumped to the rest of the body.

The condition can develop gradually over time and is often associated with aging and calcification of the aortic valve leaflets. Other causes include rheumatic fever, congenital heart defects, and certain inflammatory conditions. In its early stages, aortic stenosis may present with no noticeable symptoms. However, as the condition progresses and the heart has to work harder to pump blood, individuals may experience shortness of breath, chest pain or tightness, dizziness, fainting, and heart palpitations. Fatigue and swelling in the ankles or feet can also occur.

Diagnosis typically involves a physical examination, listening for characteristic heart murmurs, and imaging techniques such as an echocardiogram, which provides detailed views of the heart's structure and function. Electrocardiogram (ECG) and chest X-rays may also be used. Treatment depends on the severity of the stenosis and the presence of symptoms. Mild cases may be managed with medication to control symptoms and monitor the condition. For severe or symptomatic aortic stenosis, surgical or transcatheter valve replacement is often necessary to restore normal blood flow. Early detection and appropriate management are crucial for improving outcomes and preventing complications.
