A week after doctors placed a new leadless pacemaker in the upper chamber of a 64-year-old man's heart, follow-up imaging showed it had broken loose. The capsule-shaped device had flipped and moved into his right ventricle, and his heart was no longer being paced from the atrium.
Cardiologists at National Taiwan University Hospital in Taipei described how they got it out in a case report in JACC: Case Reports that appeared in the journal's Sept. 2 issue. One wire snare was not enough. It took a second snare to steady the device, followed by 3D mapping to choose a better spot for a new pacemaker.
