Right Ventricular Anatomy Can Accommodate Multiple Micra Transcatheter Pacemakers.
Bottom Line:
The introduction of transcatheter pacemaker technology has the potential to significantly reduce if not eliminate a number of complications associated with a traditional leaded pacing system.This was true even in a human heart considered to be relatively small.Although this technology is new, it was demonstrated here that within the human heart's RV, three Micra devices could be accommodated within traditional pacing locations: with the potential in some, for even more.

pace12804-fig-0001: Multiple Micras implanted as shown in photographic and fluoroscopic images. An example of the largest heart is shown in A and B (specimen 10549); an example of smallest heart is shown in C and D (specimen 10550). Mentions: Images from the largest and smallest hearts among the cadaver hearts are shown in Figure 1. An image from the reanimated heart is shown in Figure 2. The perfused cadaver hearts ranged in weight from 433.6 g to 803.2 g and in volume from 35 mL to 200 mL, with a range in A‐V distance from 6.5 cm to 9.5 cm (Table I). In addition, the body mass index for six cadavers was calculated using the National Institutes of Health calculator and ranged from 20.1 to 26.2 (Table I). |
