Aortic Valve Replacement

Also known as: aortic valve surgery, transcatheter aortic valve replacement (TAVR), transcatheter aortic valve implantation (TAVI)

What is aortic valve replacement?

Aortic valve replacement is a surgery to remove and replace the heart’s aortic valve. This may be needed if the valve leaks (aortic regurgitation) or has a narrow opening (aortic stenosis).

What happens during the procedure?

This is surgery is done under general anesthesia with cardiopulmonary bypass. Rarely the valve can be placed using catheters without undergoing open heart surgery, however most children are too small for this procedure.

Is any special preparation needed?

You may need to stop taking certain medicines before the surgery. You’ll want to take precautions to prevent infections after the surgery. You may need to stop eating and drinking the day before the surgery, as well.

What are the risk factors?

Risks of aortic valve replacement include bleeding, stroke, heart attack, infections, breathing problems, drug reactions, arrhythmia and possibly death

Lourdes Prieto, MD, Pediatric and Adult Congenital Cardiologist with Nicklaus Children's Hospital Heart Institute, explains the different procedures for heart valve replacement.

Aortic Stenosis

When someone has aortic stenosis, the aortic valve doesn't open as wide as it should. This prevents blood from flowing out of the heart at its customary rate. Learn more

Aortic Regurgitation

When someone has aortic regurgitation, the aortic valve leaks and allows blood to flow back into the left ventricle, which can cause a number of problems.  Learn more

Heart Valve Replacement Surgery

Heart valve surgery is used to repair or replace damaged or diseased heart valves. A common precursor to heart valve surgery is heart valve disease, which happens when a heart valve does not close completely, which can cause blood to flow backwards, limit blood flowing forward, cause chest pains, shortness of breath, fainting, or heart failure.
