Aortic Valve Repair Surgery

To help future patients evaluate the treatment of aortic valve disorders, I created this page to help you learn about aortic valve repair surgery. If the severity of your aortic disease requires a valvular transplant, please visit our page about aortic valve replacement.

Why Does My Aortic Valve Need To Be Repaired?

Let's start this discussion by learning more about the heart and the heart valves. The heart has four chambers, the atria and the ventricles. There are also four valves that regulate the flow of blood through the heart, keeping it moving in only one direction. The aortic valve is between the heart's left ventricle and the body's largest artery, the aorta.

In a normal aortic valve, three leaflets (also known as cusps or flaps) respond to changes in pressure to allow blood through and then close after the proper amount of blood has passed.

  • If the aortic valve cannot open and close correctly, the patient may experience further complications that can be quite serious. An aortic valve can become stenotic, or narrowed, which limits or obstructs the movement of blood. Stenosis can result from calcium deposits accumulating on the cusps. A congenital heart defect, known as a bicuspid aortic valve, can also be problematic. In this condition, the individual is born with only two flaps on the aortic valve rather than the three flaps seen on a normal valve. So you know, I had a bicuspid valve prior to my surgery.
  • If the aortic valve leaks blood back into ventricle, the ventricle must work harder to send the needed blood supply to the aorta. This condition is called aortic valve regurgitation or valvular incompetence. It is caused by the leaflets that cannot close as they should. It can result from aortic valve prolapse, a bicuspid aortic valve, endocarditis, an aneurysm, or from damages incurred from rheumatic fever.

Types of Aortic Valve Repair Surgery

Whenever possible, surgeons prefer to repair a damaged aortic valve rather than replace it. Aortic valve surgery is an open heart operation. This involves opening up the sternum, or breastbone (via median sternotomy), to provide access to the heart. Newer procedures are less invasive requiring smaller incisions, and in some cases, the operation can be performed through an incision between the ribs (known as port access or minithoracotomy), eliminating the need to divide the sternum.

The nature of the surgery needed, the aortic valve disorder, and the patient's health will determine which technique must be used. One of the most common aortic valve repair surgeries is done to reshape a bicuspid aortic valve. In this procedure, the surgeon can separate the leaflets that have been fused or surgically create a third leaflet. This repair can often be effected through minimally invasive surgery (a mini-sternotomy) which is primarily used for patients with aortic valve regurgitation.

Aortic valve repair is typically not recommended for patients with a stenotic bicuspid aortic valve. In younger patients, the surgeon may be able to remove the calcium deposits that are preventing the aortc valve from functioning properly. However, in older patients, the calcification may cause the flaps to become stiff and unyielding, making such cases impossible to remedy through a minimally invasive technique.

Here is a discussion I recently held with Dr. Lars Svensson, Director of the Aorta Program at The Cleveland Clinic, about aortic valve repair.

In some patients, the problem with the aortic valve is a tear or hole in one of the leaflets. A cardiac surgeon can often patch such holes in the valve. The surgeon will use the patient's own tissue to create a patch if one is needed. Sometimes, the cords connecting the valve to the wall of the heart are either too long or too short to allow the valve to operate properly. Surrounding tissue that provides support for the valve may also weaken. Both problems can typically be repaired through surgery on the aortic valve.

Often, repairing an aortic valve involves treating an enlarged ascending aorta, the first section of the blood vessel leading from the valve. If the enlarged area is less than four or five centimeters is diameter, the area can often be repaired. However, larger areas may require the weakened section to be replaced with a dacron graft.

Risks of Aortic Valve Repair Surgery

Aortic valve surgery is one of the most performed types of cardiac surgery. As such, overall risks are low, however complications can arise and their can be challenges faced by the patient during the recovery from aortic valve repair or any cardiac procedure. Recent studies, from The Society of Thoracic Surgeons, suggest that mortality rates for aortic valve surgery is a little over 2 percent.
