What is the replacement of the percutaneous valve?
Percutaneous valve replacement is a type of non -surgical procedure in which the heart valve is replaced by a guide tube known as a catheter. The catheter is inserted into the artery into a weakness and passed into the heart until it reaches the patient valve. At the end of which the replacement valve is mounted, it passes through the catheter until the new valve is placed over the old, the wire with the balloon passes. The balloon is inflated, opens a new valve and provides it on site. Finally, the balloon is released and the catheter and the wire are downloaded and leave a new valve in the position.
The first replacement of the percutaneous valve was made in France in 2002. This type of valve replacement allows you to implant a new valve without the need for open heart surgery. A relatively new technique was used to treat the condition known as aortic stenosis, in which the aortic valve is narrower than usual. This reduces blood flow from the heart to the main arterua known as Aorta, which adds oxygenated blood to most of the body. Pain may be requiredOn the chest, breathless, weakness and palpitation and repair of the valve or replacement of the valve.
When aortic stenosis is severe, valve repair operations may not be appropriate. Replacing the aortic valve may be the only treatment option with the potential to improve symptoms and increase the patient's survival. We hope that replacing the percutaneous valve can provide this treatment for patients who are too patient to undergo an open heart surgery. When the replacement of the percutaneous valve is used to replace the aortic valve, the technique can also be referred to as the implantation of the transcatheter aortic valve.
Preliminary results of one large randomized, controlled studies indicate that the replacement of percutaneous valve could be a suitable alternative to standard non -surgical treatment. This standard treatment consisted of drugs, patient monitoring and repair for expansion aortic valve with a balloon known aso valvuloplastics. One of the main complications of the valve -related valvulastics in the adult is that the aortic valve tends to narrow again after treatment.
patients in a study who were not sufficiently fit for conventional surgery and who were treated with percutaneous valve substitute rather than standard treatment, they had the risk of dying by 20 percent. The future research results should allow doctors to compare the effectiveness of replacing the percutaneous valve against the operation of the open heart surgery to replace the aortic valve. This could result in replacing the percutaneous valve standard, rather than an experimental method of aortic stenosis.
