Percent of patients who underwent implantation of new permanent pacemaker or ICD during or after index procedure

All subjects who are brought into the procedure room and any of the following have occurred: anesthesia administered, vascular line placed, TEE placed, or any monitoring line placed. Additionally, these patients did NOT have ICD or PPM at the time of the index procedure.

Resheath or recapture success rate (where attempted) where a successful resheath is defined as the intended portion of the Evolut R is resheathed into the capsule of the delivery catheter to the intended amount, as verified by flouroscopy; and a successful recapture is defined as the entire Evolut R TAV (including the frame) is full resheathed into the capsule of the delivery catheter until there is no gap between the capsule and the tip , as verified by flouroscopy. Resheath or recapture wa attempted in a subset of patients. Success rate is calculated as successful resheath or recaputure events in the number of total events. Resheath anad recapture is only possible during the index procedure.

65 patients had resheath or recapture feature used during the 241 attempted procedures.

Mean gradient by Doppler echocardiography.
