This article has been updated

Transvenous leads that deliver pacing therapy to the heart via a subcutaneous pacemaker cause complications in approximately 12.5% of patients implanted with the device. In a new study published in NEJM, the Micra Transcatheter Pacing Study Group describe a newly designed leadless transcatheter pacemaker that is as safe and efficacious as conventional transvenous systems.

Patients who met class I or II guideline-based indications for pacing were enrolled into the study, and implanted with the leadless pacemaker. The primary safety end point was freedom from system-related or procedure-related complications, whereas the primary efficacy end point was the composite of a low and stable pacing capture threshold at 6-month follow-up.

    In the version of the Research Highlight initially published online and in print, the text "29.3% had an adequate 6-month pacing capture threshold" should have read "98.3% had an adequate 6-month pacing capture threshold". The error has been corrected for the HTML and PDF versions of the article.
