Aortic Valve Treatment

Transcatheter aortic valve replacement, or TAVR, is a new alternative for some cases of aortic valve stenosis. This hybrid procedure typically is done by a cardiac surgeon and an interventional cardiologist.

The diseased valve may be repaired using a ring to support a person's own valve, or the entire valve may be removed and replaced by an artificial valve. Artificial valves may be mechanical or tissue.

Valvuloplasty is performed, in certain circumstances, to open a stenotic (stiff) heart valve. In valvuloplasty, a very small, narrow, hollow tube (known as a catheter) is advanced from a blood vessel in the groin through the aorta into the heart. Once the catheter is placed in the valve to be opened, a large balloon at the tip of the catheter is inflated until the leaflets (flaps) of the valve are opened. Once the valve has been opened, the balloon is deflated and the catheter is removed.

In some cases, surgery on the malfunctioning valve can help alleviate symptoms. Examples of heart valve repair surgery include cutting scarred flaps so they open more easily; remodeling valve tissue that has enlarged; or inserting prosthetic rings to help narrow a dilated valve. In many cases, heart valve repair is preferable, because a person's own tissues are used.

When heart valves are severely malformed or destroyed, they may need to be replaced with a new mechanism. Replacement valve mechanisms fall into two categories: tissue (biologic) valves, which include animal valves and donated human aortic valves, and mechanical valves, which can be metal, plastic, or another artificial material.

The aortic root is where the aorta attaches to the heart.

The David's valve-sparing aortic root replacement method (named after Dr. Tirone David) is a surgical treatment for aneurysms of the aortic root. This method allows the aneurysm to be repaired while the existing aortic valve is preserved, helping to avoid the need for long-term anticoagulant (blood thinner) medication and helping to reduce the risk of stroke or endocarditis.

If the patient's aortic valve is diseased or cannot be used during surgery, a bioprosthetic valve can be used, also helping to prevent the need for long-term anticoagulation medication.
