Key result
Micra leadless pacemaker implantation using right ventricular angiography was successfully performed in 9 patients, with procedure times of 30-100 minutes and stable parameters at 1 month.
Observational (n=9)
No
Leadless pacemaker implantation guided by right ventricular angiography is feasible and yields stable short-term pacing parameters even in a low-volume center.
May support selective angiography-guided Micra use in low-volume centers; hypothesis-generating and requires prospective validation.
Aim: The Micra™ Transcatheter Pacing System is a leadless pacemaker that has been introduced recently. We share our experience in a low volume center and the use of right ventricular angiography (RVA) during implantation. Materials & methods: Patients underwent Micra implantation and RVA was performed to predetermine the implant site.Results: Nine patients underwent Micra implantation. The most common indication was atrial fibrillation with bradycardia. The device was implanted at apical-septum in seven and mid-septum in two. The procedure time ranged from 30 to 100 min and fluoroscopic time 4–18 min. Pacing parameters remained stable after 1-month follow-up. Conclusion: The Micra implantation technique can be easily learnt. RVA was helpful in selecting an appropriate site for the Micra implant.

Johar et al. (2018) conducted an observational in Atrial fibrillation with bradycardia (n=9). Micra Transcatheter Pacing System implantation with right ventricular angiography was evaluated on Procedure time, fluoroscopic time, and pacing parameters. Micra leadless pacemaker implantation using right ventricular angiography was successfully performed in 9 patients, with procedure times of 30-100 minutes and stable parameters at 1 month.
