Transcatheter aortic valve replacement (TAVR)

What it is

The aortic valve is located between the pumping chamber on the left side of the heart and the aorta, which is a major artery. The aorta carries oxygen-rich blood from the heart to the rest of the body. The valve should be closed while the heart is filling with blood. When the heart chamber squeezes to push blood into the aorta, the valve should open fully to allow blood flow.

Transcatheter aortic valve replacement (TAVR) is a means of replacing your aortic valve that is narrowed by a method which is much less invasive than traditional aortic valve replacement surgery.

Reasons for Procedure

TAVR allows physicians to replace a severely narrowed aortic valve due to aortic stenosis without a conventional chest incision.

Aortic stenosis is a condition that results from narrowing of the aortic valve in the heart. When this narrowing occurs it can put increased stress and pressure on the heart muscle. This can lead to many symptoms,  including chest discomfort or pain, shortness of breath, leg swelling, fatigue, or fainting. Left untreated, the heart muscle can weaken over time resulting in worsening of symptoms and premature death. The most common cause of aortic stenosis is degenerative (age related calcium deposits).

Alternatives to TAVR

  1. Medical Therapy – There are certain medications that may be prescribed to alleviate some of the symptoms of aortic stenosis. These do not stop the progression of the disease.
  2. Conventional Aortic Valve Replacement – Your aortic valve is replaced through a large incision on the front of your chest while on a heart-lung machine.
  3. Balloon Aortic Valvuloplasty – A balloon is inserted into your aortic valve through a catheter which temporarily enlarges the valve opening. This may result in a three to six month improvement of symptoms but has not been shown to prolong your life.

Possible Complications
If you are planning to have a valve replacement, your doctor will review a list of possible complications, which may include:

  • Infection
  • Bleeding
  • Irregular heart rhythm
  • Scarring
  • Blood clot formation resulting in a stroke or kidney damage
  • Valve does not function correctly
  • Complications from anesthesia

Some factors that may increase the risk of complications include:

  • Other heart conditions
  • Lung conditions
  • Chronic illness, including high blood pressure and diabetes
  • Increased age
  • Infections
  • Smoking
  • Obesity

What to Expect

Prior to Procedure
Before your procedure you will meet with one or more of the physicians to discuss your history. You will then likely be referred for further testing which may help determine if the TAVR procedure is right for you. This testing may include:

  • Cardiac Catheterization. A small catheter is threaded into your heart from a blood vessel in your arm or leg. This is done to obtain images of your coronary arteries.
  • Transesophageal Echocardiogram. A small camera is passed through your esophagus to obtain high quality images of your heart.
  • Computerized Tomography (CT) of chest, abdomen and pelvis. Contrast solution is injected into a vein followed by CT scan images to determine the best approach and valve size.

Talk to your doctor about your medication. You may need to stop taking certain medication for one week before surgery, such as:

  • Blood-thinning drugs, such as warfarin (Coumadin)
  • Anti-platelet drugs, such as clopidogrel (Plavix) 
  • Diabetes medications, such as metformin (Glucophage)

Your doctor may also ask you to:

  • Do not eat or drink anything after midnight, unless told otherwise by your doctor.
  • Arrange for a ride to and from the hospital.
  • Arrange for help at home after the procedure.

Anesthesia
TAVR is done with general anesthesia. You will be asleep.

Description of the Procedure
The most common approach for the TAVR procedure is:

  • Transfemoral – A catheter is inserted through the artery in your groin area and carefully passed up into the heart. Your new valve is then implanted through this catheter inside the narrowed valve.

After the Procedure
You will be monitored in an intensive care unit after the procedure. When you wake up, you will notice that you are attached to a number of devices, which may include:

  • Monitors to track your heart rate, breathing rate, blood pressure, and the percentage of oxygen in your bloodstream
  • A catheter in your bladder to drain urine
  • An IV to provide fluids, electrolytes, and pain medicines directly into a vein

How Long Will It Take?
The procedure can take anywhere from 2 to 4 hours.

How Much Will It Hurt?
Anesthesia will block pain during the surgery. You will be given pain medicine to help manage the pain after the surgery.

Average Hospital Stay
The usual length of stay is one night. The length of stay will depend on your overall health and your recovery progress.

Postoperative Care
You will be taken to the Intensive Care Unit (ICU) after your TAVR, where you will be cared for by skilled critical care physicians, physician assistants, nurse practitioners, nurses, therapists and technicians.  The nurses will assist you with coughing, deep breathing and getting out of bed. These are important keys to your recovery. When you are ready to leave the ICU you will move to a hospital bed for your continued recovery.

Recovering after Surgery/What to Expect
It is important for you to remember that the full recovery from your TAVR will take time. All patients take their own course, and some make faster or slower progress than others. Most patients have improvement of symptoms within one week. 

A follow-up appointment will be made about a week after your procedure.

In case of an emergency, call for medical help right away.

Patient Testimonials

B.B. procedure October 2020

“I was having a hard time breathing.  It was difficult for me to do anything around the house and even the simplest of chores was tiring.  I really wasn’t able to do very much without having to stop and rest.  I had been under the care of my cardiologist, Subroto Acharjee, MD for over 5 years and at each visit he would tell me, “Bill your heart valve is shrinking, it is opening and closing less.”  He informed me I was suffering from aortic stenosis, a condition in which the calcium deposits on the valve have built up, resulting in a narrow passage for blood to flow.   Dr. Acharjee told me about TAVR (Transcatheter Aortic Valve Replacement), a new procedure they were doing at Rockledge Regional Medical Center.  He said I was a good candidate and that it would help me get back to doing the things that I had stopped doing because I tired easily.  I had heard of valve replacements before, but I did not know anyone that had one replaced.  The Structural Heart Coordinator, Michelle Reed, RN, talked to me about the procedure and what to expect.  She assured not only me but my daughters, that everything you be ok and feeling better in no time. I checked into the hospital on Monday and was enjoying my own bed on Wednesday.  It was remarkable, I immediately was able to breathe easier and I came home with no stitches! I am able to breathe much easier and get back to doing the things I enjoy!”
