Changes of the eSheath Outer Dimensions Used for Transfemoral Transcatheter Aortic Valve Replacement

Figure 1

14 F and 16 F femoral eSheath for Edwards Sapien 3 TAVR. (a) The eSheath system expands transiently during the passage of the Sapien 3 transcatheter heart valve and abates to a lower-profile diameter thereafter. A circumferential plastic sleeve stabilized the expandable part of the eSheath at the intersection between the expandable part and the stiff bleed back prevention valve. (b) The outer diameter of the expandable part of the eSheath was measured by a digital caliper from the most distal part (0 mm) in 30 mm increments until the sleeve region (300 mm) was reached.
