Heart Narrowing: Varieties, Reasons, Remedies, and Further Insights
Heart valve stenosis, a condition where the heart valves narrow and restrict blood flow, can be a serious health concern. This article aims to provide a comprehensive overview of the common types of heart valve stenosis, their causes, symptoms, and possible treatments.
Aortic Valve Stenosis
Aortic stenosis, the most common type of heart valve stenosis, is often a result of the natural aging process or conditions present at birth. The most common cause in adults, especially the elderly, is degenerative (calcific) aortic valve stenosis, where calcification and fibrosis of the valve leaflets cause narrowing. This process shares pathophysiology similar to atherosclerosis, including risk factors like advanced age, high cholesterol, diabetes, and hypertension.
Another common cause is Bicuspid Aortic Valve (BAV) stenosis, a congenital malformation where two of the three leaflets fuse during development. This condition predisposes the valve to premature calcification and stenosis.
Rheumatic heart disease, caused by an autoimmune reaction to untreated or undertreated group A streptococcal infection, can also lead to aortic valve stenosis. This is a rare occurrence in developed countries due to widespread antibiotic use but remains a significant cause in lower-income areas.
Symptoms and Diagnosis
Stenosis of the heart may not cause symptoms at first. However, if symptoms do appear, they may include chest pain, unusually fast heart rate, difficulty breathing, unusual dizziness or lightheadedness, changes in exercise or activity tolerance, swelling of the ankles or feet, difficulty sleeping, or needing to sleep sitting up.
An echocardiogram is typically used to help doctors understand treatment options for someone with stenosis of the heart.
Prognosis and Treatment
Around 50% of people with mitral stenosis may not survive 10 years from the time their symptoms begin. In people with pulmonary hypertension due to mitral stenosis, survival time may be around 3 years.
Possible treatments for stenosis of the heart include medications, valve repair surgery, and valve replacement surgery. The choice of treatment depends on several factors, including the severity of the stenosis, the patient's overall health, and their personal preferences.
Regular monitoring and lifestyle strategies such as avoiding smoking and maintaining a moderate weight can improve the outlook for aortic stenosis. If a person has symptoms or if their symptoms are mild, doctors may recommend regular follow-up appointments and monitoring.

- Aortic valve stenosis, a common type of heart valve disease, can stem from natural aging, congenital malformations, or rheumatic heart disease caused by streptococcal infection.
- The symptoms of heart valve stenosis may not present initially, but can include chest pain, a rapid heart rate, difficulty breathing, and swelling in the ankles or feet.
- Treatment for heart valve stenosis depends on the severity of the disease, the patient's overall health, and their preferences, with options ranging from medications to valve repair or replacement surgeries.
- Regular monitoring, avoiding smoking, and maintaining a moderate weight can improve cardiovascular health and the prognosis for aortic stenosis, making it crucial for patients to adhere to medical-conditions and health-and-wellness guidelines.
