Key result
Posterosuperior bundle area pacing achieves stable lead fixation and preserves interatrial synchrony in case reports.
Why the study?
Atrial pacing has traditionally targeted the right atrial appendage, but alternative sites like Bachmann's bundle are under investigation for improved pacing outcomes.
Does posterosuperior bundle (PSB) area pacing provide stable fixation and interatrial synchrony in patients requiring atrial pacing?

Does posterosuperior bundle (PSB) area pacing provide stable fixation and interatrial synchrony in patients requiring atrial pacing?
Posterosuperior bundle area pacing is demonstrated as a novel atrial pacing modality with efficient anatomical access, stable fixation, and preserved interatrial synchrony.
PSB area pacing may provide stable fixation and synchrony in select cases; hypothesis-generating and leaves open prospective validation before practice change.
Atrial pacing has developed into a commonly adopted modality in the right atrial appendage (RAA), which has remained unchanged since its introduction decades ago. Bachmann's bundle (BB) pacing is an alternative to RAA pacing, which is currently being studied.1 In this article, we describe 2 consecutive cases in which we initially targeted BB and utilized atrial sensing amplitude as the electrical marker; however, both ultimately resulted in successful pacing in the posterosuperior bundle (PSB) area, demonstrating a novel atrial pacing modality within the superior vena cava (SVC), superior and posterior to the level of BB verified by follow-up computed tomography (CT) imaging, in which the pacing lead could efficiently access during implantation, and provided stable fixation and reserved interatrial synchrony at 11- and 9-month follow-ups.

Qiu et al. (2024) conducted a case report in Need for atrial pacing (n=2). Posterosuperior bundle (PSB) area pacing was evaluated on Successful pacing, stable fixation, and reserved interatrial synchrony. Posterosuperior bundle area pacing was successfully achieved in 2 cases, providing stable lead fixation and reserved interatrial synchrony at 9- and 11-month follow-ups.
