Key result
Three Micra transcatheter pacemakers could be successfully accommodated within traditional pacing locations in the right ventricle of seven human hearts without physical device interactions.
Why the study?
Does the human right ventricle accommodate multiple Micra transcatheter pacemakers without physical interaction?
Population
7 human hearts (6 human cadaver hearts and 1 reanimated human heart not deemed viable for transplant)
Design

RV supports ≥3 Micra devices without interaction; leaves open in vivo feasibility, patient selection, and end-of-service strategies.
Does the human right ventricle accommodate multiple Micra transcatheter pacemakers without physical interaction?
The human right ventricle can anatomically accommodate up to three Micra transcatheter pacemakers without physical interaction, supporting the feasibility of abandoning depleted devices and implanting new ones at end of service.
Omdahl et al. (2015) studied Pacemaker indication / Device life-cycle management (n=7). Implantation of three Micra transcatheter pacemakers was evaluated on Physical accommodation of three Micra devices in the right ventricle without physical interaction. Three Micra transcatheter pacemakers could be successfully accommodated within traditional pacing locations in the right ventricle of seven human hearts without physical device interactions.
