A: Transcatheter pacing system (TPS) device highlighting the proximal retrieval feature. B: TPS held in device cup with tines straightened and with device cup pulled back to allow tines to engage tissue. C: Assembly including the Arctic Front FlexCath Steerable Sheath (AF sheath) into which the Marinr catheter and Lasso snare were placed. The inset shows the distal end of the AF sheath with the TPS device cup attached and the Marinr catheter and Lasso snare projecting beyond the distal end of the cup.

Steps in capturing the transcatheter pacing system (TPS). A: Intracardiac echo image of the TPS in the apex of the right ventricle with the retrieval feature shown at the top (arrow). B: The TPS with lasso snare around the waist of the retrieval feature. The ablation catheter used to steer the snare to the device can also be seen in the picture. C: The TPS being pulled into the Arctic Front FlexCath Steerable Sheath (AF sheath) that was guided to the TPS using the snare as a rail. D: The TPS pulled into the cup on the AF sheath ready for removal from the body.

Endocardial surface after extraction. The white tissue is likely the fibrous response to the presence of the transcatheter pacing system (TPS). The void in the middle of the white tissue (arrow) is where the TPS was implanted, with the thicker encapsulation tissue surrounding the distal end of the TPS.
