Remodel the heart. Restore life

Tricuspid valve
The tricuspid valve is located between the right atrium and the right ventricle. The right atrium is where low-oxygen blood is conducted before it is pumped into the lung by the right ventricle. The tricuspid valve prevents blood from flowing back into the veins.

Aortic valve
The aortic valve is between the left ventricle of the heart and the ascending aorta, which pumps blood to the brain, muscles and organs.

Mitral valve
The mitral valve regulates the blood flow between the left atrium and the left ventricle. Oxygen-rich blood is moved from the lung into the left atrium and then led to the left ventricle and into the body.

Pulmonary valve
The pulmonary valve manages the blood flow from the right ventricle to the pulmonary artery, which is where the blood moves from the body into the lungs and where it picks up oxygen.


The structure and function of the human heart

As a rule, our heart beats 60 to 80 times a minute — our whole life long. The heart’s task is to supply oxygen-rich blood to the rest of the body.
 
The heart has four chambers: a right and left atrium and a right and left ventricle. There is a total of four valves positioned between the atria and ventricles.
 
As the name suggests, the valves act as vents which ensure that blood does not regurgitate, i.e. that it only flows in the intended direction. Blood is led from the atria into the ventricles, and then the ventricles contract, pumping blood into the vessels. The blood moves from the right ventricle to the lung and from the left ventricle to the rest of the body via the aorta.

Diseases of the cardiac valves

The heart powers the body; it gives us life and energy. Valvular heart disease can have a major impact on a patient's wellbeing or even be life-threatening.
 
If one or more of the cardiac valves do not close properly, have hardened or narrowed, not enough blood will be transported, which means that the body will not have enough oxygen or nutrients. This can cause shortness of breath, water retention and feeling faint.
 
Our vision is to remodel the heart and restore the lives of patients with valvular heart disease.

Aortic stenosis

In aortic stenosis (also called aortic valve stenosis), deposits have formed on the aortic valve and obstruct it. The cause is often age-related wear and tear, which is why older patients are more commonly affected. The valve no longer opens fully, and as a result, blood flow is restricted. The heart then has to work harder to transport the same amount of blood. This constant strain can damage and fatigue the heart muscle.
 
Replacing the aortic valve is often the only viable treatment. However, as the patient’s age increases, the risks of open-heart surgery increase as well, which means that surgical replacement of the valve is not a therapeutic option in many cases.
 
In transcatheter aortic valve implantation (TAVI), the ALLEGRATM replacement valve by New Valve Technology is folded over itself and guided to where it needs to be via a catheter inserted through the groin. It is unfolded at the appropriate site, presses the natural valve against the wall of the heart, and the new valve immediately takes over its function.

Advantages of a transcatheter valve implantation (TAVI)

  • General anesthesia is not necessary; local anesthesia is enough to keep the patient pain-free.
  • The heart keeps functioning naturally during the operation; there is no need to interrupt cardiac function as is the case in open-heart surgery.
  • The patient’s circulatory system keeps functioning normally; a heart-lung machine is not needed.
  • The chest and shoulder girdle muscles remain stable and intact since the rib cage does not need to be cut open.
  • The anticipated hospital stay is much shorter than after open-heart surgery.
  • Subsequent rehabilitation measures help restore the patient’s physical strength much faster.
  • The patients’ recovery period is much shorter and their quality of life improves.
