In the area of the aortic valve, the procedure is largely identical to a normal transcatheter aortic valve implantation (see TAVI). If there is a risk of coronary artery occlusion, the procedure can additionally be performed using the BASILICA technique.
In the area of the mitral valve, the access route differs. The procedure is performed via the inguinal vein and via the atrial septum.
If anatomically suitable, patients whose mitral valve has been surgically repaired and a mitral ring implanted (mitral valve reconstruction) can also be treated. The procedure is also performed via the inguinal vein and the atrial septum (valve-in-ring TAVI).
