Q25.3
Supravalvular aortic stenosis
Clinical Classification Guidelines
Excludes Type 1
- congenital aortic stenosis NOS (Q23.0)
- congenital stenosis of aortic valve (Q23.0)
Medical Intelligence & Overview
Supravalvular Aortic Stenosis (SVAS) is a rare congenital heart defect characterized by a narrowing of the aorta just above the aortic valve. This condition limits blood flow from the heart to the rest of the body, potentially leading to increased heart workload and other cardiovascular complications. Recognizing the symptoms and understanding the causes can aid in timely diagnosis and management of the condition.
Causes & Symptoms
Clinical Causes: Genetic factors, including associations with Williams syndrome Congenital malformation during fetal development Rarely, acquired conditions that cause narrowing of the aorta over time
Key Symptoms: High blood pressure in the arms Weak or absent pulse in the groin or legs Chest pain or discomfort Difficulty breathing or shortness of breath Fainting or dizziness, especially during exertion Heart murmur detected through physical examination Signs of heart failure in severe cases
Diagnostic & Treatment
Diagnosis Path: Echocardiogram (ultrasound of the heart) to visualize the narrowing and assess heart function Cardiac MRI or CT scan for detailed imaging Cardiac catheterization to measure blood pressure gradients and confirm the severity
Treatment Protocols: Monitoring mild cases without significant symptoms Surgical interventions, such as patch aortoplasty, to remove or bypass the narrowed segment Balloon angioplasty, a minimally invasive procedure to widen the aorta in selected cases Medications to manage symptoms and associated conditions, such as antihypertensives
