heavily calcifi ed valve, and no paravalvular leaks were observed around the
frame (Fig. 5.9). These investigations, and others, following the same proce-
dures, confi rmed that the fl exibility of the CoreValve delivery catheter is
compatible with antegrade transarterial access over the femoral or subcla-

Animal studies
Animal studies have been carried out to confi rm the feasibility of percuta-
neous heart valve replacement on a beating heart. A sheep model was
employed for these studies, using aortic implantation with a self-expandable
cardiac tissue valve prosthesis. The security and effi cacy during and after
implantation were investigated by studying:
