Congenital aortic stenosis, a prevalent heart valve disorder, poses significant health challenges by narrowing the aortic valve and obstructing blood flow. This article delves into its causes, symptoms across different age groups, and diagnostic methods. Explore the treatment options available and understand the importance of early detection and management to improve patient outcomes and quality of life.
Understanding Congenital Aortic Stenosis
Congenital aortic stenosis is a heart valve disorder characterized by the narrowing of the aortic valve, which obstructs blood flow from the heart’s left ventricle to the aorta. This condition reduces the supply of oxygen-rich blood to the body’s organs and tissues, leading to various health complications (source). The primary cause of this condition is often a congenitally abnormal valve, such as a bicuspid or unicuspid valve, which can lead to left ventricular outflow obstruction. It is the most common cause of aortic stenosis in patients under 70 years in developed countries (source).
Key Symptoms of Congenital Aortic Stenosis
Symptoms of congenital aortic stenosis can vary significantly depending on the age of the patient and the severity of the condition. In infants, symptoms may include fatigue, cyanosis, and feeding difficulties. As children grow older, they may experience dizziness, fainting, and chest pain, especially during physical activity (source). In adults, early symptoms may not be noticeable, but as the condition progresses, symptoms can include shortness of breath, chest pain, fatigue, fainting, and heart palpitations, particularly during exertion (source). The onset of symptoms often occurs after a long asymptomatic period, typically 10 to 20 years, with initial symptoms like exertional dyspnea and fatigue progressing to more severe symptoms such as heart failure and syncope (source).
Diagnosis and Treatment Options
Diagnosing congenital aortic stenosis involves several tests. A physical examination can detect heart murmurs, while an echocardiogram is used to visualize heart structure and function. An electrocardiogram checks for abnormal heart rhythms, and cardiac catheterization measures pressure and evaluates stenosis severity (source). Echocardiography is the standard method for evaluating aortic stenosis, allowing for the assessment of valve anatomy and severity, which is crucial for stratifying patients for potential surgical intervention (source).
Treatment options depend on the severity of the condition. For mild cases, regular monitoring may suffice, while severe cases might require interventions such as balloon aortic valvuloplasty, surgical aortic valvotomy, or aortic valve replacement. These procedures aim to improve blood flow and alleviate symptoms (source). Aortic valve replacement (AVR) is the definitive treatment for severe symptomatic aortic stenosis and is recommended even for mild symptoms and in certain asymptomatic patients with severe stenosis, based on specific clinical criteria (source).

Understanding the symptoms and treatment options for congenital aortic stenosis is crucial for early detection and management. Early intervention can significantly improve outcomes, as mortality rates increase after symptom onset. Without treatment, the average survival is only 1 to 3 years post-symptom onset (source). Regular follow-up care with a cardiologist is essential for managing the condition and preventing complications such as heart failure, aortic aneurysm, and infective endocarditis (source). By staying informed and vigilant about potential symptoms, individuals and families can ensure timely evaluation and personalized treatment, ultimately improving quality of life and health outcomes.
