زرع الصمام الأبهري عبر الصمام (TAVI)
نحن نعالج الترجمة Transcatheter aortic valve implantation (TAVI) is a procedure used as an alternative to open heart surgery in treating severe aortic stenosis, a condition which is commonly found among elderly patients. It will be performed if the doctor feels that a patient would be put at risk by the more invasive open heart surgery.
The doctor will begin the implantation of an artificial heart valve by first inserting a catheter into the patient's body via the femoral artery (located in the groin), or by piercing the tissues at the apex of the heart through a small incision in the chest. When the catheter is guided towards and reaches the aortic valve, the doctor will then inflate a balloon within the catheter, placing pressure on the artificial heart valve and securing it in position. The new artificial heart valve will then replace the existing aortic valve as its condition continues to deteriorate. This procedure normally takes around 2-3 hours.
Based on these criteria, a doctor will consider which method of treatment is suitable for each patient.
The risks associated with implanting an artificial heart valve using a catheter are as follows:
