Aortic subvalvular stenosis, also known as subaortic stenosis, is a cardiovascular condition characterized by the narrowing or obstruction of the aorta, the main artery that carries oxygen-rich blood from the heart to the rest of the body. This condition primarily affects the area just below the aortic valve, where the aorta connects to the heart's left ventricle.
In aortic subvalvular stenosis, the narrowing or constriction can be caused by a variety of factors, such as a thickened or abnormal tissue growth in the inner lining of the aortic wall. This narrowing creates an obstacle to the smooth flow of blood, resulting in increased pressure and workload on the heart.
Symptoms of aortic subvalvular stenosis can vary depending on the severity and progression of the condition, but common signs may include chest pain, shortness of breath, fatigue, dizziness, and fainting.
Diagnosis of aortic subvalvular stenosis typically involves a comprehensive evaluation of the patient's medical history, physical examination, and cardiac imaging techniques like echocardiography, magnetic resonance imaging (MRI), or computed tomography (CT) scan.
Treatment for aortic subvalvular stenosis may involve medication to control symptoms, but in more severe cases, surgical intervention is often required. Surgical options vary based on the severity and location of the stenosis, but they can include procedures like open-heart surgery, balloon valvuloplasty, or the removal of obstructive tissue.
Careful monitoring and regular follow-up appointments with a cardiologist are generally necessary for individuals with aortic subvalvular stenosis to manage symptoms and prevent complications.
