A novel temporary atrioventricular sequential pacing catheter-Characteristics and first-in-human application

Area of Science:

• Cardiology
• Biomedical Engineering
• Medical Devices

Background:

• Sequential synchronized atrioventricular (AV) pacing enhances electrophysiologic and hemodynamic parameters compared to ventricular pacing.
• Current temporary transvenous pacemakers lack the capability for AV sequential pacing.
• A novel multilead pacemaker device (TAVSP) was developed for improved temporary pacing.

Purpose of the Study:

• To present the structural components and mechanical properties of a novel temporary sequential synchronized AV pacing device.
• To report the first-in-human application and early clinical experience of the TAVSP device.

Main Methods:

• The TAVSP device underwent development and proof of concept in an animal model.
• The novel catheter was inserted transvenously during heart catheterization in 10 patients.
• Device deployment, activation in AV sequential mode, and performance were analyzed under fluoroscopy or echocardiography.

Main Results:

• The TAVSP device was successfully inserted, delivered, and deployed in all 10 patients.
• All patients achieved proper pacing thresholds and impedance, with adequate ventricular lead performance.
• No adverse events, technical difficulties, or component failures were observed; the device was safely retrieved.

Conclusions:

• Initial human use of the novel TAVSP demonstrates feasibility and safety.
• The TAVSP modality offers potential for improved pacing and hemodynamic benefits.
• Further clinical application studies are warranted for this new pacing catheter.
