2 Fig 1 Valve positioning. (A, B) The introducer tube is advanced 2 to 4 cm into the left ventricle until the retainer faces the end of the pigtail curl (thick arrow). Alignment is obtained looking at a small window located on the top of the valve commissure. The central commissural post is positioned posteriorly (circle and thin arrow) and the crimped control arms above the cusps (dashed arrows). The protruding surface of the retainer should always be toward the right side of the screen (brace) and the flat surface toward the left side of the screen (thick arrow). (C) Aortographic view showing the aortic cusps. Small windows of (B) adapted from Medtronic with permission (© Medtronic 2015). Angiographic images are from patients of this series.

3 Fig 2 Valve implantation. (A) Releasing the control arms. (B) Pulling the device and seating the control arms into the native aortic cusps. (C) A second view better depicts the position of the right control arm (dashed arrows) seating in the right coronary cusp of the native aortic valve, which is located anteriorly (center of screen). (D) Aortographic view confirming accurate position. Thin arrows depict the central commissural post, located posteriorly, and the pigtail catheter (white arrowhead) in the noncoronary cusp. Black arrowhead depicts the left coronary cusp. A and B adapted from Medtronic with permission (© Medtronic 2015). Angiographic images are from patients of this series.

4 Fig 3 Valve releasing and deployment. (A) Releasing the commissure posts. (B) Bioprosthesis self-deployment. (C) Retrieving the delivery system. (D) Engager valve at the end of the transapical aortic valve implantation. Thin arrow depicts the central commissural post, located posteriorly, and the pigtail catheter (white arrowhead) in the noncoronary cusp. Black arrowhead depicts the left coronary cusp. A and B adapted from Medtronic with permission (© Medtronic 2015). Angiographic images are from patients of this series.
