Summary
Day case MICRA implantation is safe for selected patients. This study found low complication rates, supporting its use as an outpatient procedure for leadless pacemakers.
Area of Science:
- Cardiology
- Medical Devices
- Outpatient Procedures
Background:
- Micra implantation is typically not a day-case procedure.
- Elective leadless pacemakers are routinely implanted at our center.
Purpose of the Study:
- To assess the safety and feasibility of performing Micra implantation as a day-case procedure.
- Evaluate complication rates and device function in same-day discharge patients.
Main Methods:
- Retrospective data collection from 81 patients undergoing elective Micra implantation (May 2014 - Nov 2022).
- Patients stratified into same-day (SD) discharge (n=52) and overnight observation (ON) (n=29) groups.
- Recorded demographics, sheath size, device type, and complication rates; evaluated device function post-implant.
Main Results:
- Micra implantation was successful in 80 patients.
- Major complication rates were 2% in the SD group and 7% in the ON group (p=0.223).
- 98% of SD patients and 96% of ON patients had low and stable pacemaker lead threshold at follow-up.
Conclusions:
- Day-case Micra implantation is safe in appropriately selected patients.
- Outpatient leadless pacemaker procedures can be performed with low complication rates.
- Supports the expansion of day-case procedures for leadless pacemaker implantation.
