Surgeons at the University hospital Schleswig-Holstein, Germany are testing a new method to replace defective heart valves: remove from the heart of your patient’s body’s own tissue and forms a new flap. Since these keep a long time, the process is particularly for young patients is advantageous.
If a heart valve is defective, replace cardiac surgeons this so far, by artificial Valves or heart valves of animals – usually from pigs or cattle. In the case of an artificial heart valve, the patients have to take then your life-long medication, because otherwise the danger of blood clots forming that can trigger seizures. In the animal heart, this is a damper is not necessary, but they have a lifespan of a maximum of 15 years. Often you will need to be replaced much sooner.
Now heart want surgeons to use the advantages of a new method, which was developed by the Japanese Shigeyuki Ozaki. It is removed during the Operation, a small part of the pericardium, and from this, a suitable new flap is formed, which replaces the defective. Since these Flaps are elastic, fit you better than artificial Flaps on the flow conditions, which prevents blood clots. As a result, the patient can dispense with the intake of anticoagulants.
Further research is needed
Since it is the body’s own Material, it also comes to disturbing immune responses that limit the valves, the durability of the animal heart. "We hope that these important points to the long-term effects of aortic valve rate, and thus on the prognosis of the patient auswirken", Prof. Dr. med said. Armin Welz, heart surgeon and Chairman of the Scientific Advisory Board of the German Foundation for heart research. Experience with these new heart valves so far there are only a few. In order for the changes to be tested the new method in three major sub-projects in comparison to the conventional methods.
The heart has valves four heart. They work like valves that regulated the blood flow out let. If a heart valve is not sufficiently open, it is called a stenosis. The heart muscle must work against an increased resistance, in order to promote the blood in the circulatory system. The heart is overused and increasingly weakened. Then the organs of the body are supplied with enough oxygen and nutrients.
