For the treatment of Aortic Valve Disease: Stenosis and Regurgitation
Aortic valve surgery is performed by heart surgeons to treat most commonly bicuspid valves, other congenital aortic valve disease, aortic valve stenosis and aortic valve regurgitation.
This information will help you understand the conditions that may affect the aortic valve and why surgical treatment may be needed to treat your condition.
What is the aortic valve?
There are four valves in your heart including the mitral, tricuspid, aortic and pulmonic valves.
The aortic valve is located between the left ventricle (lower heart pumping chamber) and the aorta, which is the largest artery in the body. Valves maintain one-way blood flow through the heart.
Aortic valve disease occurs when the aortic valve does not work correctly. This can be caused by:
The aortic valve may be abnormal at birth (typically a bicuspid congenital aortic valve) or become diseased over time, usually seen in older patients (acquired valve disease).
Patients with bicuspid aortic valves are born with them and are present in about 1 - 2 percent of the population.
Normal aortic valve
Bicuspid aortic valve
Instead of the normal three leaflets or cusps, the bicuspid aortic valve has only two. Without the third leaflet, the valve opening may not close completely and leak (regurgitant) or not open completely and become narrowed (stenotic) or leak.
In many cases, bicuspid aortic valves may function normally for several years without requiring treatment.
About 25 percent of patients with bicuspid aortic valves may have some enlargement of the aorta above the valve. If it is greatly dilated, the aorta is known as being aneurismal.
With acquired aortic valve conditions, changes occur in the structure of the valve. Acquired aortic valve conditions include:
Many patients with aortic valve disease are asymptomatic (have no symptoms), even when the stenosis (narrowing) or insufficiency (leak) are severe.
Initial symptoms of aortic valve disease usually include:
More advanced symptoms may include:
The diagnosis of aortic valve disease is made after your physician reviews your symptoms, performs a physical exam and listens for a murmur, and evaluates the results of your diagnostic tests.
During the physical exam, using a stethoscope, the doctor may hear a murmur, which represents turbulent blood flow across an abnormal valve.
The diagnosis of aortic valve disease is confirmed by a specialized heart ultrasound called an echocardiogram. The echocardiogram allows the doctor to visualize the heart valves and determine the severity and possible cause of the aortic valve disease.
In most patients, a standard transthoracic echocardiogram (in which a probe with gel is placed on the skin of the chest to transmit the images) is adequate to visualize the valve. The test may be combined with exercising or IV infusion of drug allow the doctor to see the degree of stenosis more clearly.
Sometimes, a transesophageal echocardiogram (TEE - in which a probe is passed through the mouth into the esophagus) is necessary to more closely visualize the valve. A TEE is an outpatient procedure.
If you do not have symptoms or heart damage, you will need to protect your valve from further damage by following precautions to reduce the risk of infective endocarditis, and you may need to take medications. In addition, surgery may be needed to treat your condition if you have symptoms, evidence of heart damage, or heart failure.
There are two types of aortic valve surgery: aortic valve repair and aortic valve replacement.
During aortic valve surgery, including aorta surgery, the aortic valve may be repaired or replaced. The results of your diagnostic tests, the structure of your heart, your age, the presence of other medical conditions and other factors will be considered to determine whether aortic valve repair or replacement is the best treatment approach for you.
Aortic valve surgery can be performed using traditional heart valve surgery or minimally invasive approaches.
Traditional Aortic Valve Surgery
During traditional aortic valve surgery, a surgeon makes a 6- to 8-inch incision down the center of your sternum, and part or all of the sternum (breastbone) is divided to provide direct access to your heart. The surgeon then repairs or replaces your abnormal heart valve or valves.
Minimally Invasive Aortic Valve Surgery
Minimally invasive aortic valve surgery is a type of aortic valve repair surgery performed through smaller, 2- to 4-inch incisions without opening your whole chest. This is typically done with a “J” incision and leaves your chest stable. Minimally invasive surgery reduces blood loss, trauma, length of hospital stay and may accelerate recovery.
Most patients who require isolated aortic valve surgery are candidates for minimally invasive aortic valve surgery, but your surgeon will review your diagnostic tests and determine if you are a candidate for this type of surgery.
While the aortic valve is usually replaced, aortic valve repair may be an option.
Bicuspid aortic valve repair
A bicuspid aortic valve may be repaired by reshaping the aortic valve leaflets allowing the valve to open and close more completely.
Bicuspid aortic valve repair may be an option to treat leaking valves, but it can not be used to treat a stenotic or narrowed bicuspid aortic valve.
Bicuspid aortic valve repair can be performed using a minimally invasive “J” incision surgical technique. The aortic valve surgery is technically difficult and should be performed by a surgeon with experience repairing aortic valves.
Repair of an enlarged aorta
Aortic valve disease is often associated with enlargement (aneurysm) of the ascending aorta, the initial portion of the aorta (the main blood vessel in the body that originates from the aortic valve).
If the enlargement of the aorta is substantial (usually above 4.5 or 5 cm in diameter), this part of the aorta may need to be replaced. The replacement is done at the time of aortic valve repair or replacement. In patients who have leaky aortic valve and an enlarged aorta, a special procedure (David procedure) can be performed. The David procedure allows surgeons to repair the aortic valve and simultaneously replace the enlarged ascending aorta.
Repair of valve tears or holes
In addition, if the valve leaflets have tears or holes, the surgeon can patch these with tissue patches.
If valve repair is not an option, your surgeon may replace the valve. The native (original) valve is removed and a new valve is sewn to the annulus of your native valve. The new valve can either be mechanical or biological.
Biological valve replacement
At Cleveland Clinic, the majority of aortic valves are replaced with a bioprosthesis. Biological valves (also called tissue or bioprosthetic valves) are made of tissue, but they may also have some artificial parts to provide additional support and allow the valve to be sewn in place.
About 80% of aortic valves are replaced with a bioprosthesis.
Biological valves can be made from pig tissue (porcine), cow tissue pericardial (bovine), or pericardial tissue from other species.
These valves are safe to insert, durable (lasting from 15 to 20 years), and allow patients to avoid lifetime use of anticoagulants (blood thinning medications). At the Cleveland Clinic the risk of death is less than one percent for isolated aortic valve replacement and has consistently been better than predicted mortality based on the Society of Thoracic Surgeons (STS) national data.
Human Homograft (also called allograft) aortic valve replacement
A homograft is an aortic or pulmonic valve that has been removed from a donated human heart, preserved, treated with antibiotics, and frozen under sterile conditions.
Homografts are used especially when the aortic root is destroyed by endocarditis (infection).
Mechanical valves replacement
Mechanical valves are made completely of mechanical parts, which are non-reactive and tolerated well by the body. The bileaflet valve is used most often.
It consists of two pyrolite (qualities similar to a diamond) carbon leaflets in a ring covered with polyester knit fabric.
All patients with mechanical valve prostheses need to take an anticoagulant medication, warfarin (Coumadin), for the rest of their life to reduce the risk of blood clotting and stroke. This increases the risk of bleeding.
Ross Procedure (also called Switch Procedure)
The Ross operation is usually performed on patients under age 30 who want to avoid lifetime use of anticoagulants (blood thinning medications) after surgery.
During this procedure, the patient's normal pulmonary valve is removed and used to replace the diseased aortic valve. The pulmonary valve is then replaced with a pulmonary homograft. The Ross procedure leaves two valves at potential risk of later failure.
At Cleveland Clinic, the overall risk of death associated with surgery for isolated aortic valve replacement is less than 1%, compared with The Society of Thoracic Surgeon's benchmark of 2.4%.Mortality for minimally invasive "j" incision isolated aortic valve replacement is even lower and mortality for minimally invasive isolated aortic valve repair is also extremely low even for the David valve preserving procedure.Past history of heart surgery, your age, co-existing organ disease (such as emphysema), or other conditions that require surgical treatment will affect your individual risk.
