Figure 2 Sequential steps of implantation. (A) The percutaneous valve in position across the native calcific aortic valve before delivery. GW = extra-stiff guide wire; PM = pacemaker lead in the right ventricle for brief period of rapid pacing at the time of balloon inflation; Sones = Sones catheter advanced over the guide wire from the left femoral artery. (B) Balloon inflation for valve delivery. (C) Post-implantation supra-aortic angiogram showing mild aortic regurgitation. (D) Right anterior oblique-cranial view of the valve showing the circular stent frame pushing away the calcified native valve. Selective left (E) and right (F) coronary angiogram post-implantation showing patent coronary ostia.
