1. An intravenous (IV) line will be started for fluids and medication.
2. You will be given sedation to make you drowsy and a local anesthetic will be injected at the insertion site, normally the groin.
3. The doctor will insert a catheter with a small deflated balloon at one end through the artery and up into the mitral valve. X-ray is used to visualize this. A transesophageal echocardiography is used to confirm the location of the balloon.
4. Once the balloon-tipped catheter is in place, it is inflated and deflated several times. The balloon pushes open the mitral valve and stretches the valve opening, improving blood flow.
5. The balloon is deflated and the catheter is guided back out of your body.
6. The procedure takes about 1-2 hours to complete.
