Direct wire pacing during measurement of fractional flow reserve: A randomized proof-of-concept noninferiority crossover trial.

Background: Adenosine administration for fractional flow reserve (FFR) measurement may induce heart pauses.

Aims: To assess the accuracy and tolerability of direct wire pacing (DWP) during measurement of FFR.

Methods: Adults with at least one intermediate coronary artery stenosis (40%-80%) were consecutively enrolled between June 2021 and February 2022 in this randomized, noninferiority, crossover trial (NCT04970082) carried out in France.

A direct wire pacing device for transcatheter heart valve and coronary interventions: a first-in-human, multicentre study of the Electroducer Sleeve.

Background: Transcatheter aortic valve implantation (TAVI) and complex percutaneous coronary interventions (PCI) may require cardiac pacing during device delivery, generally requiring the insertion of a temporary pacing lead via an additional venous access site. The purpose-built Electroducer Sleeve device provides direct wire pacing without the need for a temporary venous pacemaker.

Aims: This study assessed the safety of temporary cardiac pacing using the novel sleeve device during PCI.

Direct Wire Pacing for Challenging Left Main Stenting: An Old Technique Revived.

During stent positioning after predilating with a non-compliant balloon, we observed major motion of our device in the left main coronary artery. Under those conditions, accurate stent placement was uncertain. To remedy this situation, we decided to perform a rapid direct wire pacing with a good final angiographic result.
