I35.2 Nonrheumatic aortic (valve) stenosis with insufficiency

Name of the Condition

• Nonrheumatic aortic (valve) stenosis with insufficiency

Summary

Nonrheumatic aortic valve stenosis with insufficiency is a condition where the aortic valve both narrows (stenosis) and leaks (insufficiency), impairing blood flow from the heart to the aorta and causing backward flow into the left ventricle. This dual abnormality increases the heart's workload and can lead to symptoms such as chest pain, shortness of breath, or fatigue. Unlike rheumatic valve disease, it is not caused by rheumatic fever.

Causes

Causes may include age-related degeneration, calcification of the valve, congenital defects (e.g., bicuspid valve), aortic root dilation, or damage from previous infections or trauma. The combination of stenosis and insufficiency often results from progressive valve damage over time.

Risk Factors

• Advanced age
• Hypertension
• Atherosclerosis
• Family history of valve disease
• Prior heart infections or surgeries
• Certain genetic conditions

Symptoms

• Chest pain or tightness
• Shortness of breath (especially during activity)
• Fatigue or weakness
• Dizziness or fainting
• Heart palpitations
• Swelling in the ankles or feet

Diagnosis

Diagnosis typically involves a physical examination, echocardiogram (to assess valve function and structure), electrocardiogram (ECG) to check heart rhythm, and sometimes cardiac MRI or CT scans. Blood tests may be used to rule out other conditions. Doppler echocardiography is particularly useful for evaluating both stenosis and insufficiency.

Treatment Options

Treatment depends on severity and may include medications to manage symptoms (e.g., diuretics, vasodilators) or surgical intervention (valve repair or replacement) for severe cases. Monitoring is common for mild or asymptomatic presentations.

Prognosis and Follow-Up

Prognosis varies based on severity and response to treatment. Regular follow-up with imaging (e.g., echocardiograms) is important to monitor valve function and heart health. Severe cases may require timely intervention to prevent complications.

Complications

• Heart failure
• Arrhythmias
• Endocarditis
• Sudden cardiac events

Lifestyle & Prevention

• Manage blood pressure and cholesterol
• Avoid smoking
• Maintain a heart-healthy diet
• Engage in regular, moderate exercise (as advised)
• Treat infections promptly to reduce endocarditis risk

When to Seek Professional Help

Seek care if experiencing new or worsening chest pain, severe shortness of breath, fainting, or rapid heart palpitations. Prompt evaluation is critical for symptom management and preventing progression.

Tips for Medical Coders

Document the presence of both stenosis and insufficiency to support the I35.2 code. Ensure clinical notes specify the valve's functional status (e.g., echocardiogram findings) and exclude rheumatic causes, as this code is specific to nonrheumatic etiologies.
