Treatment and study plan

Primary outcomes

  1. Correlation of HemoCept device measurements with aortic valve pressure gradient changes.

    Time frame: Perioperative; immediately before procedure, and up to 24 hours after the procedure

    The primary endpoint is the ability of the HemoCept device to properly detect changes consistent with aortic valve pressure gradient values, measured by echocardiogram pre and post TAVR procedure.
