A number of years ago, a new and minimally-invasive surgical technique has become established for the treatment of high-risk patients with aortic stenosis that is designed to replace the aortic valve without opening the thorax and without the patient having to be connected to a heart-lung machine. With transcatheter aortic valve implantation (TAVI), transfemoral or transapical insertion of a catheter is performed, a balloon catheter is used to burst the old heart valve and the new aortic valve is brought into position with a guide wire and subsequently positioned.
Some of our perfusionists are certified to use at least one TAVI system. During the procedure, they are responsible for preparing the system, for ensuring that the valve is correctly crimped and for checking the loader. They also provide stand-by circulatory support in the event of complications with the implantation of the TAVI device.
