Direct Wire Pacing technique
(DWP®)

DWP® is a direct cardiac stimulation technique using PCI* or TAVI* guidewires.
(wire which allow stent or valve delivery to the heart).

Direct Wire Pacing (DWP®) technique

More and more frequently, percutaneous cardiovascular interventions (complex PCI, TAVI, TTVR*, TMVR*) require temporary cardiac stimulation. Usually, this is generated via a temporary pacing catheter inserted through a dedicated venous access that are both likely to generate vascular or cardiac complications.
To reduce these potentially life-threatenin complications and the complexity of the procedure, a new stimulation strategy has been developed: the “Direct Wire Pacing technique». In this approach, the cardiac stimulation is provided via the interventional guidewire and a cutaneous anode both connected to an external pacemaker.

This is breakthrough technique for interventional cardiology which has already been partially adopted by cardiological community.
The Direct Wire Pacing technique is at the origin of the development of the Electroducer® Sleeve medical device.

*PCI: Percutaneous Cardiovascular Interventions
*TAVI: Transcatheter Aortic Valve Implantation
*TTVR: Transcatheter Tricuspid Valve Replacement
*TMVR: Transcatheter Mitral Valve Replacement

Why is it better using DWP®?

A multicentre randomized controlled trial (EASY TAVI) performed in 2019 on 302 patients comparing the Direct Wire Pacing technique to the standard RV-stimulation (temporary pacing catheter), was able to show superiority of DWP® technique.

While avoiding the implantation of a catheter dedicated to temporary cardiac stimulation in the right ventricle, the Direct Wire Pacing® technique:

Optimized

Reduces procedure duration and radiation exposure for the patient and the operator (fluoroscopy time)

Safer

Tend to avoid the complications (displacement, stable positioning…) related to the implantation of a catheter in a high-risk zone by offering the same stimulation efficacy as a stimulation probe

Costs effectiveness

Reduces hospital costs considering the pacing material removal, time saving and the avoided complications

Electroducer® aims to avoid the many handling errors found when using the standard technique, which should further increase the observed performance gains and medical community adoption.
