Aortic Valve Replacement

Aortic Valve Replacement

Aortic Valve replacement is a procedure that is required if there is a problem in the aortic valve of your heart. When this valve opens, the blood from your heart goes to the aorta and on to the rest of your body. When the aortic valve closes, it helps to keep blood from flowing the wrong way back into your heart. With every heartbeat this cycle keeps repeating. If there is something that goes wrong with your valve, it can interfere with the blood flow, which can force the heart to work harder to send blood to the rest of your body. In such a condition, your doctor might recommend surgery for replacing it. Generally, your doctor initially considers repairing the aortic valve. However, when valves can’t be repaired, heart valve replacement is considered.


There are several types of valve diseases for which aortic valve replacement might be considered. Some of them include:

Aortic valve regurgitation- This condition is known to occur when your blood flows backward through your aortic valve into the left ventricle each time the ventricle relaxes. Normally, blood is supposed to flow in one-way direction from the ventricle to the aorta. A dysfunctional or a leaky valve can lead to the backflow. This may be due to the valve deteriorating, an abnormal valve shape present at birth or due to an infection.

Aortic valve stenosis- The stenosis can lead an aortic valve to become narrowed or obstructed, which can make it even more difficult for the heart to pump blood into the aorta. This may be caused by multiple factors, such as congenital heart disease, thickening of the valve’s closure flaps or post-inflammatory changes, such as those which are associated with rheumatic heart disease.

Congenital heart disease- This can contribute to either aortic valve regurgitation or stenosis. It can also result in other problems that can prevent the proper functioning of the aortic valve. For example, a person might be born with an aortic valve not having enough tissue flaps or there may not be an opening in the valve to allow normal blood flow. The valve can also be of the wrong shape of size.

For some people who are having mild aortic valve disease without any symptoms, careful monitoring under an experienced doctor’s supervision might be all that is required.

However, in many cases aortic valve disease and dysfunction can worsen over time despite medical treatment. Most aortic valve conditions are mechanical problems that are not treatable with medications alone. Such conditions can eventually require surgery for reducing symptoms.

Your doctor and healthcare team will decide whether to go for repair or replacing the heart valve. It can depend on various factors, such as the severity of your aortic valve disease, your age and overall health or whether you require any heart surgery for any additional heart problem.


Before you undergo the surgery for having your aortic valve repaired or replaced, your doctor and treatment team will be explaining what you can expect before, during and after your surgery as well as the potential risks the surgery may cause.

You need to discuss with your doctor and the treatment team any questions you might have about your procedure.

Before you are admitted to the hospital for your surgery, talk to your caregivers about your hospital stay and discuss any help you may require when you return home.

Also remember to talk to your doctor about when you can resume taking your medications regularly and whether you will be able to take them before your surgery. Also, ask whether you should stop eating or drinking the night before the surgery. You may also need to bring several items to the hospital including a list of your medications, eyeglasses, hearing aids, etc.


For the aortic valve replacement procedure, you will be receiving anesthetics so that you will not be feeling any pain. You will be unconscious during the procedure.

You will be connected to a heart-lung bypass machine, which will keep your blood moving through your body during the procedure.

First, your doctor will be removing the aortic valve and replacing it with a mechanical valve or a valve made from a pig, cow or human heart tissue (valve).

Often biological tissue valves eventually need replacement as they degenerate over time. If you have a mechanical valve, you will require blood-thinning medications for the rest of your life for preventing blood clots. Doctors will be discussing with you the risks as well as the benefits of each type of valve and discuss which valve is appropriate for you.

The surgery can be performed through traditional open-heart surgery or minimally invasive methods. It involves smaller incisions than those used in open-heart surgery. There is another type of minimally invasive aortic valve replacement which is known as transcatheter aortic valve replacement.

However, minimally invasive aortic valve replacement is generally less common since not all situations are best addressed by this method of access to the damaged valve. Results similar to those with traditional open-heart surgery can be achieved if it is performed by experienced surgeons.

After the procedure

If you had open-heart surgery, you will generally require spending a day or more in the ICU. You will receive oxygen, fluids, medications as well as nutrition through the intensive care unit. Other tubes will be draining urine from your bladder, draining fluid and blood from your chest.

Later you’ll be moved to a regular hospital room where you will need to spend some days. The amount of time you will spend in the ICU and hospital may vary depending on your condition and procedure.

During your stay at the hospital, your treatment team will be watching for signs of infection in your incision sites. They will also be checking your blood pressure, breathing and heart rate periodically. If you experience pain after the surgery, they will be working with you in managing it.

Your doctor might also advise you to avoid driving a car or lifting anything more than 10 pounds for a few weeks.


There are certain risks associated with aortic valve replacement. The type of procedure and the expertise of your health care team also plays a role.

Although most people do well during this surgery, it might lead to a few problems, which include:

  • Bleeding after surgery
  • Infection
  • Blood clots
  • Heart rhythm getting thrown off for a while
  • Kidney problems that can last for multiple days after surgery
  • Stroke
  • New valve not functioning or wearing out over time


Although rare death can also occur in a few cases. To minimize risk it is recommended that the surgery is performed by an experienced team of qualified doctors.

Aortic Valve Replacement & Aortic Valve Repair

Aortic valve repair and aortic valve replacement are procedures that treat diseases affecting the aortic valve. Types of Aortic Valve Surgery are:

  • An annuloplasty is a procedure to tighten or reinforce the ring around a valve in the heart.
  • A valvuloplasty, also known as balloon valvuloplasty or balloon valvotomy, is a procedure to repair a heart valve that has a narrowed opening.

Open Heart surgery versus Catheter method of Heart Replacement

Traditionally, all valve replacement procedures required a open-heart surgery. However, recent advances in catheter methods have resulted in the development of catheter- based (non-surgical)  heart valve replacement procedures.

The Catheter based  approach to Valve Repair is generally recommended in case of Valve Stenosis (condition in which the valve narrows down).The procedure is called Transaortic Valve Implantation/ Replacement (TAVI/TAVR) for Aortic Valve Repair. In case of Mitral Valve Repair, it is called Transaortic Mirtral Valve Implantation/ Replacement (TMVI/R).

TAVI / TMVI is the first line of treatment in cases of Valve narrowing /stenosis.

The advantage of TAVI/TMVR is that in this procedure, the valve is replaced with no scar (unlike surgery) and recovery time is minimal. 

However, in cases of Valve Regurgiation (leakage), surgery is still required / recommended.
