Subaortic Membrane Resection

Also known as: subaortic resection.

What is subaortic membrane resection?

Subaortic membrane resection is a surgery that’s used to repair a medical condition known as subaortic stenosis. With subaortic stenosis, the area just below the aortic valve of the left ventricle is obstructed or narrowed often by excess tissue, which reduces the flow of blood to the body.

What happens during the procedure?

Subaortic membrane resection is an open-heart surgery performed under general anesthesia with the use of a heart-lung bypass machine. The surgeon will open the chest and then the aorta near the aortic valve. The subaortic membrane is removed, which will restore the flow of blood from the left ventricle to the body.

Is any special preparation needed?

You may need to avoid food or drink, as well as certain medications, for a period of time before the procedure.

What are the risk factors?

Risk factors of subaortic membrane resection include bleeding, infection, a hole in the heart, damage to the aortic valve, heart rhythm problems or a portion of the membrane being left in the heart.
