Description of intervention(s) / exposure
Treatment: Devices - Medtronic CoreValve® System

Experimental: Medtronic CoreValve® System Implantation - Patients with symptomatic severe aortic stenosis who have an elevated surgical risk


Treatment: Devices: Medtronic CoreValve® System

AND (Assessment of Surgical Risk)

* Cirrhosis of the liver (Child class A or B)
* Pulmonary insufficiency : VMS < 1 liter
* Previous cardiac surgery (CABG, valvular surgery)
* Porcelain aorta
* Pulmonary hypertension > 60 mmHg and high probability of cardiac surgery for other than valve replacement
* Recurrent pulmonary embolus
* Right ventricular insufficiency
