NCT05528029

Brief Summary

The Micra MC1VR01 or Micra AVMC1AVR1 Transcatheter Pacing System (Medtronic, Inc., Minneapolis, MN, USA) has become a major breakthrough as an alternative to standard transvenous pacemakers. The aim of this multi-center study is to assess the clinical outcomes of patients implanted with Micra LLPM in real life, in different clinical scenarios.

Outcome Measures

Primary Outcomes (6)

  • All cause mortality

    overall mortality

    through study completion, an average of 2 years

  • Implant complication rates

    Dislodgments, Cardiac perforation, vascular complications (access site).

    during and immediately after the intervention

  • Electrical performance of the pacing system

    Pacing thresholds

    Through study completion, an average of 2 years

  • Electrical performance of the pacing system

    R wave sensing

    Through study completion, an average of 2 years

  • Electrical performance of the pacing system

    pacing impedances values

    Through study completion, an average of 2 years

  • Upgrading with a different pacing system

    Need of an additional transvenous pacing system

    Through study completion, an average of 2 years

Interventions

Micra leadless pacemaker is implanted in the right ventricle via femoral vein. The Micra introducer/dilator assembled system is inserted over a stiff guidewire in the right atrium. After the removal of the guidewire and the dilator, the delivery system is advanced into the introducer and the Micra is placed under fluoroscopy guidance, preferably in the septal region of the right ventricle.
