Catheter Aortic Valve Replacement in Turkey

Aortic valve replacement using a catheter

What is TAVR (Transarterial Aortic Valve Replacement)?

 Through this small operation, the new heart valve is placed over the diseased valve, whereby a new valve is obtained without surgery.

How does a valve work inside a valve?

This valve functions similarly to the meshes used to dilate coronary (coronary) vessels when they are clogged (due to myocardial infarction).

As soon as the new heart valve is placed, it removes the old valve and replaces it in regulating blood movement.

How is aortic valve replacement using a TAVR or TAVI catheter different from surgical valve replacement?

This operation is performed for those who have stenosis of the aortic valve but who cannot perform an open heart operation due to the presence of accompanying diseases.

What is involved in TAVR aortic valve replacement?

Valve replacement usually requires an open heart procedure with a "sternum incision", where the chest is surgically separated (opened) for replacement, while TAVR or TAVI can be done through very small incisions that leave all of the breastbone in place.

Although every operation, no matter how small, has several risks, the risks of this operation are very few, as it is similar to placing a stent in the coronary arteries, and it also provides a good option for patients who do not have the opportunity to change the valves through surgery, and there are two methods for this operation, the doctor chooses the best for your case :

First method:

The angiologist inserts the cardiac catheter from the femoral or radial artery, which does not require a surgical incision in the chest. Many patients are treated with sedative drugs and local anesthesia, which are called non-hypnotic narcotics. The valve is reached with the help of interventional radiology and the artificial valve is placed in place of the old valve.

Second method:

The second procedure is done by entering through a very small incision in the chest and then accessing the aortic valve.

Catheter Aortic Valve Replacement Risks in Turkey

As mentioned, all operations involve some kind of risk, no matter how small. The risks of transcatheter aortic valve replacement (TAVR) may include the following:

  • hemorrhage
  • Reposition of the heart valve after transplantation
  • vascular problems
  • Bleeding in the skin area where the femoral artery was entered
  • Bleeding due to the diluted medicines that the patient uses most often
  • Kidney failure due to medications given during the operation that may cause anaphylactic shock (a very small percentage)
  • irregular heartbeat and the need for Implantation of a pacemaker
  • Heart attack
  • septic infection

Is Catheterized Aortic Valve Implantation (TAVI) better, or Laparoscopic Aortic Valve Surgery? robot?

Recently approved by the U.S. Food and Drug Administration (FDA), this procedure is an alternative to surgery for a patient with aortic valve stenosis if surgery is high-risk.

There are significant differences between standard aortic valve surgery and TAVI.

TAVR may also be an option if you have a biological valve that was previously implanted to replace the aortic valve but is now not working well.

Who is a suitable candidate for aortic valve replacement without surgery?

Patients who undergo a TAVI procedure are usually in their 70s or 80s, so they have other concomitant health problems, and these patients benefit most when using minimally invasive methods with a rapid recovery.

Although it is a new method, it significantly increases the quality of life in patients with aortic valve disease who do not have a surgical alternative, because it prevents further damage to the heart, increases the quality of life and increases the length of survival, which cannot be achieved with drug therapy.

The quality of life - as I explained Studies Short term on this operation - it was similar with the surgery, but so far there are not enough studies on the preference of choosing treatment by catheter or by surgery.

But the installer so far via this study Several other studies show that transcatheter heart valve replacement is the gold standard for patients with symptomatic aortic valve stenosis who are classified as high risk for intervention.

Common Questions

The aortic valve is replaced using a catheter by inserting a somewhat mesh-like valve through the femoral artery with a cardiac catheter where the new valve is placed inside the affected valve.

In young patients, the valve is permanently replaced surgically, whether through a robot, through a minimally invasive surgery, or through an open-heart surgery. However, in elderly patients or those who have a weak heart and cannot perform open heart surgery, aortic valve replacement using catheters is recommended because it allows the valve to be replaced with a minimal risk with increased longevity.

Robotic aortic valve replacement has better results than aortic valve replacement using a catheter if the patient can perform surgery.

The cost of aortic valve replacement in Turkey ranges between 8 and 20 thousand US dollars.

The success rate of TAC in Turkey is approximately 95%.
