Asymmetric Septal Hypertrophy: Causes, Signs, and Treatment
Asymmetric septal hypertrophy is a heart condition characterized by the abnormal thickening of the heart muscle wall (septum) that separates the chambers of the heart. This thickening can lead to changes in the heart's structure and function, impacting overall heart health. The condition can affect how efficiently the heart pumps blood, potentially leading to various complications and reducing the heart's ability to function optimally.
What are the Symptoms of Asymmetric Septal Hypertrophy?
Individuals with asymmetric septal hypertrophy may experience various symptoms related to heart function.
- Shortness of breath
- Chest pain
- Heart palpitations
- Fatigue
- Dizziness or lightheadedness

Get Second OpinionCauses of Asymmetric Septal Hypertrophy
Asymmetric septal hypertrophy is primarily caused by genetic mutations that lead to abnormal thickening of the heart muscle, affecting its function.
- Genetic mutations
- Hypertension
- Aortic stenosis
- Athletic heart syndrome
- Cardiomyopathy
- Fabry disease
- HCMassociated mutations
- Hypertrophic cardiomyopathy
Types of Asymmetric Septal Hypertrophy
Asymmetric septal hypertrophy can manifest in various forms, each presenting distinct characteristics and implications for the affected individual's health.
- Hypertrophic Cardiomyopathy (HCM): A common type of asymmetric septal hypertrophy characterized by thickening of the heart muscle, leading to potential blockage of blood flow.
- Noonan Syndrome: A genetic disorder associated with heart abnormalities, including asymmetric septal hypertrophy, along with distinct facial features and developmental delays.
- Fabry Disease: An inherited metabolic disorder that can cause asymmetric septal hypertrophy due to the buildup of certain fats within cells.
- Friedreich's Ataxia: A progressive neurodegenerative disorder that can also involve cardiac complications, such as asymmetric septal hypertrophy.
- Danon Disease: A rare Xlinked disorder that affects muscle and heart function, often leading to hypertrophic cardiomyopathy with asymmetric septal hypertrophy.
Risk Factors
Asymmetric septal hypertrophy risk factors include a family history of the condition, certain genetic mutations, and high blood pressure.
- Family history of hypertrophic cardiomyopathy
- High blood pressure
- Older age
- Diabetes
- Obesity
- Sedentary lifestyle

Diagnosis of Asymmetric Septal Hypertrophy
Asymmetric septal hypertrophy is typically diagnosed through a combination of medical history review, physical examination, and specialized tests.
- Echocardiogram
- Electrocardiogram (ECG)
- Cardiac MRI
- Cardiac CT scan
- Genetic testing
Treatment for Asymmetric Septal Hypertrophy
Asymmetric septal hypertrophy is generally managed through a combination of lifestyle modifications and medical interventions.
- Medications: Pharmacological treatment may include betablockers or calcium channel blockers to help manage symptoms and improve heart function in patients with asymmetric septal hypertrophy.
- Septal Myectomy: Surgical procedure to remove a portion of the thickened septum in the heart, improving blood flow and reducing symptoms in severe cases of asymmetric septal hypertrophy.
- Alcohol Septal Ablation: Minimally invasive procedure involving the injection of alcohol into the targeted septal artery to induce controlled damage and reduce septal thickness in patients who are not candidates for surgery.
- Implantable CardioverterDefibrillator (ICD): Device implanted under the skin to monitor heart rhythm and deliver electric shocks if dangerous arrhythmias occur in patients with asymmetric septal hypertrophy at risk of sudden cardiac death.
- Lifestyle Modifications: Adopting a hearthealthy lifestyle, including regular exercise, a balanced diet, weight management, and avoiding smoking, can help improve overall heart health and manage symptoms of asymmetric septal hypertrophy.

What is asymmetric septal hypertrophy?
Asymmetric septal hypertrophy, also known as asymmetric septal thickening, is a heart condition characterized by the abnormal thickening of the heart's septum, which separates the left and right ventricles.
What are the symptoms of asymmetric septal hypertrophy?
Symptoms may include chest pain, shortness of breath, fatigue, dizziness, and fainting. Some individuals may not experience any symptoms.
What causes asymmetric septal hypertrophy?
The exact cause is unknown, but it is often linked to genetic factors. It can also be associated with conditions such as hypertension or aortic stenosis.
How is asymmetric septal hypertrophy diagnosed?
Diagnosis typically involves an echocardiogram to visualize the thickened septum and assess heart function. Other tests may include an ECG, MRI, or genetic testing.
What are the treatment options for asymmetric septal hypertrophy?
Treatment may involve medications to manage symptoms and prevent complications. In some cases, procedures like septal myectomy or alcohol septal ablation may be recommended to reduce the thickness of the septum.
