Aortic valvuloplasty

Overview

Diagram of aortic valvuloplasty procedure

Aortic valvuloplasty is a medical procedure used to treat aortic valve stenosis, a condition characterized by the narrowing of the aortic valve opening. This procedure is typically performed to improve blood flow from the left ventricle of the heart to the aorta and subsequently to the rest of the body.

Indications

Aortic valvuloplasty is primarily indicated for patients with severe aortic stenosis who are not suitable candidates for aortic valve replacement surgery. It is often considered a palliative treatment to relieve symptoms such as dyspnea, angina, and syncope.

Procedure

The procedure involves the insertion of a balloon-tipped catheter into the femoral artery and advancing it to the aortic valve. Once in position, the balloon is inflated to widen the valve opening, thereby improving blood flow. The procedure is usually performed under local anesthesia with sedation.

Steps

1. Access: The femoral artery is accessed using a needle and guidewire. 2. Catheterization: A catheter is threaded through the artery to the heart. 3. Balloon Inflation: The balloon is positioned across the aortic valve and inflated to dilate the valve. 4. Deflation and Removal: The balloon is deflated and removed, and the catheter is withdrawn.

Risks and Complications

While aortic valvuloplasty is less invasive than surgical valve replacement, it carries certain risks, including:

• Vascular complications at the access site
• Stroke
• Aortic regurgitation
• Arrhythmias

Outcomes

The procedure can provide symptomatic relief and improve hemodynamics in patients with aortic stenosis. However, the effects are often temporary, and many patients may eventually require valve replacement.
