Figure 1: Right anterior oblique cineangiographic views of a patient (Patient 1) during Micra™ entirely leadless pacemaker implantation. (a) Positioning of the deployment catheter above the right ventricular apex as shown by contrast injection. (b) Deployed Micra™ which was still attached by a tether. (c) Tines were in the retracted state (arrow). (d) Straightening of the tines (arrow) when the tether was pulled, thus demonstrating good fixation.
