What is Transcatheter Aortic Valve Replacement?

The aortic valve in your heart can be replaced with transcatheter aortic valve replacement (TAVR), eliminating the need for open cardiac surgery. This minimally invasive procedure is now the most widely used way to replace an aortic valve.

The aortic valve is the last of the four heart valves that control blood flow. Your heart pumps oxygen-rich blood into your aorta and throughout your body through that valve.

Research suggests that TAVR is generally less dangerous than surgical aortic valve replacement (SAVR) and produces results comparable to or better than SAVR. Repair valves consist of tissue from cows or pigs encased in a metal frame.

TAVI, or transcatheter aortic valve implantation, is another name for this procedure.

What is the treatment for transcatheter aortic valve replacement?

Aortic stenosis is the most frequent cause of transcatheter aortic valve replacement. It is the narrowing of the vicinity around your aortic valve. Typically, narrowing results from:

Wear and tear brought on by aging, particularly in those over 70, may cause the valve to stiffen or accumulate calcium.

Other medical disorders that may hasten the degradation of the valve include bicuspid aortic valve and rheumatic heart disease.

Your heart must beat harder to compensate for the reduced blood supply to the rest of your body due to a narrowing of the valve. This typically results in permanent damage to the heart muscle, which is followed by cardiac failure.

Aortic valve replacement is necessary for many "high-risk" patients due to the severity of stenosis or other medical issues. Accordingly, individuals are more likely to experience problems following a major procedure, such as open heart surgery, or to pass away.

A transcatheter aortic valve replacement (TAVR) is also an option for individuals in different risk categories. The US Food and Drug Administration approved it in 2019 for patients with a minimal risk of surgical complications and patients with prior valve replacement surgery.

There are certain benefits to minimally invasive procedures versus surgical procedures. However, your provider will consider your unique circumstances to determine whether this operation suits you.

How should I get ready for an aortic valve replacement with a transcatheter?

The following diagnostic tests will probably be performed on you before a transcatheter aortic valve replacement. They consist of:

• Blood examinations.
• Heart-rate chart (EKG).
• A heart magnetic resonance imaging (MRI) or computed tomography (CT) scan.
• The left side of your heart is catheterized. Providers use this to gauge the blood flow throughout your heart. They can also get a sneak peek at any issues they must address.
• Your healthcare professional will discuss what to anticipate during and after the procedure after these tests. Additionally, they will discuss with you the type of anesthetic you will receive for your TAVR treatment. They can also respond to any other queries you may have.
• A transcatheter aortic valve replacement surgery requires you to fast for four to six hours before the procedure. Before your operation, find out from your provider whether you need to stop taking any specific medications and when.

What should you expect before replacing the transcatheter aortic valve?

A medical expert inserts an IV into your hand or forearm.  It is used to provide sedative medication. The drug induces drowsiness, calmness, and relaxation. Anticoagulant and anti-infective medications can also be administered intravenously.

A medical team member may shave any hair on the area of your body undergoing the operation.

What can you expect during transcatheter aortic valve replacement?

During transcatheter aortic valve replacement (TAVR), a defective aortic valve is replaced by one manufactured from cow or pig heart tissue. The pig or cow valve is known as a biological tissue valve. Physicians occasionally replace a malfunctioning biological tissue valve with a new one.

TAVR uses tiny incisions and a flexible, hollow tube known as a catheter to access the heart. It differs from aortic valve replacement surgery performed openly, which requires a lengthy cut down the chest.

A physician inserts a catheter into a blood vessel, typically in the chest or groin, to perform TAVR. Using an X-ray or other imaging technology as a guide, the physician directs the catheter to the site of the aortic valve in the heart.

The physician inserts a biological tissue valve through the catheter and places it near the aortic valve. To firmly implant the replacement aortic valve, a balloon at the catheter's tip expands. However, there are replacement valves that expand without a balloon.

After the replacement valve is firmly in position, the physician removes the catheter.

Your medical staff keeps a close eye on you during TAVR. We continuously monitor your heart rate, rhythm, blood pressure, and respiration.

What can you expect after a transcatheter aortic valve replacement?

After the TAVR procedure is finished, an anesthesiologist will cease the anesthesia or sedation, enabling you to awaken. However, they will put you in bed for several hours at least to halt the bleeding. This is because the huge blood vessel where the catheter was inserted is the reason for the delay in moving you until the specialists are certain the stitches are in place.

Your doctor could prescribe medication to prevent blood clots or infections after the treatment.

Benefits of aortic valve replacement by transcatheterization

Compared with open cardiac surgery, TAVR - or transcatheter aortic valve replacement - has several advantages:

• Not invasive: TAVR is more minimally invasive than open heart surgery. The physical injury and complications in a patient will, therefore, be less due to the smaller number of invasions.
• Faster Recovery: Patients recover faster with a return to routine life as compared to patients who have undergone open heart surgery.
• Lower Risk to Some Patients: TAVR may offer a big alternative for some individuals who would be at a higher risk for open cardiac surgery. Risk can be predicted either by the patient's age, concomitant conditions, or perhaps other factors.
• Better Quality of Life: The aspect of TAVR that deals with a better quality of life is through alleviation of symptoms resulting from aortic stenosis, such as tiredness, shortness of breath, and pain in the chest.

What are the risks or complications associated with transcatheter aortic valve replacement?

Like any surgery and medical procedure, there are inherent risks. The TAVR does have its potential risks. These include:

• Blood vascular issues.
• Issues with the substitute valve, such as the valve moving or leaking.
• A stroke.
• Irregular heartbeats and the necessity of a pacemaker.
• Renal illness.
• Attack of the heart.

How long does it take to recover from a transcatheter aortic valve replacement?

Most patients are able to be discharged from the hospital the same day after a transcatheter aortic valve replacement. Some might need a longer period, such as two days or more, in the hospital. Based on your condition and overall health, the recovery time for you can be different after having a transcatheter aortic valve replacement.

Follow-up visits with a practitioner are anticipated one month after receiving treatment and annually thereafter. Your healthcare practitioner is the best individual to estimate how long your recuperation will take. Most patients are able to resume most of their regular activities a few days after the treatment. It may take a little longer for certain people.

Before moving heavy objects or engaging in any other physical activity, you will need to wait a week (or longer, depending on where your physician placed the catheter). After a month of recovery, you can resume driving and return to work two weeks after TAVR. It takes six to ten weeks to fully recover.

Your healthcare physician will most likely recommend a cardiac rehabilitation program. This is similar to a recommended exercise regimen involving a group of professionals from several disciplines. Start this as soon as possible after your TAVR treatment to strengthen and extend the life of your heart.

It should improve with time if you're experiencing depression following your procedure. Seek assistance from a friend or counselor in the meantime.

When should I give my doctor a call?

After the replacement of your transcatheter aortic valve, get in touch with your provider if you have:

• High temperature.
• Inflammation at the point of entry may exacerbate rather than go away.
• Either discoloration or inflammation.
• Aching in the chest.
• Breathlessness and dizziness.

The doctor who treated you will be the one to let you know when you should come back for follow-up tests. If you are started on blood thinners, then achieving optimal result post-heart-valve replacement is very important. Even these may involve diagnostic testing to ensure the new valve is functioning properly.
