Vascular support structures are an important tool for treating valve stenosis. A large population of patients is treated for valvular disease and the principal mode of treatment is the use of Percutaneous Valvuloplasty. Stent devices are proving to be an improved treatment method; these devices now account for 20% of treatments in Europe. This new technology provides highly effective results at minimal cost and with reduced hospital stays.
The treatment of stenotic valvular diseases consists of routine procedures in interventional cardiology. To date, the surgical approach is the only option to replace diseased cardiac valves. Recently is has been shown that stenosis of mitral, aortic or pulmonary valves can be treated by Percutaneous valve replacement has recently opened new perspectives on transcatheter placement of cardiac valves. Aortic valve replacement generally has been accomplished by using a cardiac surgical procedure whereas endovascular procedures for valve replacement may provide an alternative to cardiac surgery. Percutaneous transluminal procedures have substantial benefits from the standpoints of health and safety, as well as cost. Such endovascular procedures require minimal invasion of the human body, and there is considerable reduction and, in some instances, even elimination of general anesthesia and intensive care unit stay.
Surgical Replacement of Aortic Valve
Cardiac valve prostheses are well known in the treatment of heart disease. The normal method of implantation requires major surgery during which the patient is placed on a heart-lung machine and the patient's heart is stopped. Once the surgery is complete, the patient can expect an extended hospital stay and several more weeks of recuperation. A mortality rate of five percent (5%) is common. For some patients, surgery is not an option because age or some other physical problem prevents them from being able candidates for surgery due to the inherent dangers and the likelihood of death then on.
