What medications are recommended for severe aortic valve stenosis?

From the Guidelines

Medications for severe aortic valve stenosis primarily focus on managing symptoms rather than treating the valve narrowing itself, with diuretics, beta-blockers, ACE inhibitors, and statins being considered for symptom relief. The management of severe aortic stenosis involves a multidisciplinary approach, considering the patient's symptoms, left ventricular function, and surgical risk 1.

Medication Options

• Diuretics like furosemide (20-80mg daily) or hydrochlorothiazide (12.5-50mg daily) can reduce fluid retention and ease breathing difficulties.
• Beta-blockers such as metoprolol (25-200mg daily) may help control heart rate and reduce oxygen demand.
• For patients with heart failure symptoms, ACE inhibitors like lisinopril (2.5-40mg daily) or ARBs such as losartan (25-100mg daily) might be prescribed cautiously, as they can help reduce afterload and improve cardiac output 1.
• Statins like atorvastatin (10-80mg daily) may slow valve calcification progression in some patients.

Considerations

• The use of vasodilators, including ACE inhibitors and ARBs, should be done with caution in patients with severe aortic stenosis, as they can cause hypotension 1.
• Beta-blockers can be used in patients with reduced ejection fraction, prior MI, arrhythmias, or angina pectoris, but should be used with caution in patients with severe aortic stenosis due to the potential for increased diastolic filling period and regurgitant volume 1.
• Regular follow-up with a cardiologist is essential to assess disease progression and determine optimal timing for valve intervention, as medications only provide temporary symptom relief while awaiting definitive treatment.

Definitive Treatment

• Definitive treatment for severe aortic stenosis typically requires valve replacement through surgery or transcatheter procedures, such as transcatheter aortic valve implantation (TAVI) 1.
• The choice of treatment depends on the patient's symptoms, left ventricular function, and surgical risk, as well as the presence of concomitant coronary or other valve disease.

From the Research

Medications for Severe Aortic Valve Stenosis

There is limited information available on medications specifically recommended for severe aortic valve stenosis. However, the following points can be noted:

• Medical management of concurrent hypertension, atrial fibrillation, and coronary artery disease is recommended to lead to optimal outcomes 2.
• Treatment of severe aortic stenosis typically involves aortic valve replacement, which can be surgical or transcatheter, depending on the patient's risk profile 2, 3, 4.
• In patients with acute heart failure and severe aortic valve stenosis, transcatheter aortic valve implantation has emerged as an important treatment option 5.

Treatment Approaches

The following treatment approaches are recommended:

• Aortic valve replacement is recommended for most symptomatic patients with evidence of significant aortic stenosis on echocardiography 2.
• Watchful waiting is recommended for most asymptomatic patients, but select patients may also benefit from aortic valve replacement before the onset of symptoms 2.
• Surgical valve replacement is the standard of care for patients at low to moderate surgical risk, while transcatheter aortic valve replacement may be considered in patients at high or prohibitive surgical risk 2, 4.
• Treatment decisions should be made by a Heart Team, taking into account concomitant factors such as mitral regurgitation or coronary artery disease 5.
