Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Between Feb 17, 2011 and Aug 23, 2013, 656 subjects were enrolled into the CoreValve US Pivotal Trial Extreme Risk study at 41 of the 43 activated centers in the United States. Between February 2, 2011 and July 23, 2013, 797 subjects were enrolled into the CoreValve US Pivotal Trial High Risk study at 45 centers in the United States.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The first 3 successfully enrolled and implanted iliofemoral subjects at each implanting site, inclusive of both the High Risk Surgical and Extreme Risk patient populations were considered roll-in subjects, and were automatically assigned to undergo Medtronic CoreValve® System Transcatheter Aortic Valve Implantation (TAVI).

^[1]

The Society of Thoracic Surgeons (STS) risk model predicts the risk of operative mortality and morbidity after adult cardiac surgery on the basis of patient demographic and clinical variables. After information has been entered on a given case, the online STS risk calculator provides a risk percentage for each of the outcomes. The risk percentage estimates the chance of a specific outcome for a patient with the indicated risk factors. A higher score indicates a higher risk. A lower score indicates a lower risk.

^[1]	The European System for Cardiac Operative Risk Evaluation (EuroSCORE) is a method of calculating predicted operative mortality for patients undergoing cardiac surgery. If a risk factor is present, a weight/number is assigned. The weights are added to give an approximate percent of predicted mortality. A higher score indicates a higher risk. A lower score indicates a lower risk.
