Figure 1
The Micra leadless pacemaker (Medtronic Inc, Minneapolis, MN): before (A) and after (B) pull-and-hold test. Note the 4 tines (black arrows) on the distal end of the Micra device that adhere to the myocardium. Opening of the tines after the pull-and-hold test, as seen in Figure 2B, is an indicator of adequate fixation.
Figure 2
Figure 2
Chest radiographs demonstrating location of the Micra pacemaker (Medtronic Inc, Minneapolis, MN), both immediately (A) and 1 day (B) following implantation. The position of the Micra pacemaker remained unchanged on chest radiograph (arrow).
