Left Bundle Branch Area Pacing 3D Guidance System

Heart Failure Clinical Trial

Official title: Left Bundle Branch Area Pacing Study Designing the 3D Hybrid Guidance System for Implantation of Cardiac Devices

Status Not yet recruiting

Clinical Trial Summary

The investigator's project proposes the development of a 3D hybrid guidance system which has the aim of avoidance of scar and septal perforation through targeted lead deployment via a personalised septal real time image overlay onto x-ray fluoroscopy imaging during left bundle branch pacing. The investigators hypothesise that the use of cardiac anatomy and myocardial scar distribution derived from cardiac magnetic resonance imaging (MRI) as well as 3D position of the pacing lead, may improve LBBAP lead deployment success and improve clinical outcomes by guiding the physician towards optimal lead positioning.

Clinical Trial Description

The study will use anonymised imaging data from the TACTIC-CRT (IRAS 250715) , Cardiac CT to guide Cardiac Resynchronisation Therapy (CRT) implantation (IRAS 150161) study (IRAS 150161) and anonymous cardiac MRI, CT and fluoroscopy imaging data from patients who underwent LBBA pacing to develop a 3D hybrid guidance system using machine learning methods. The developed 3D hybrid guidance system will be tested on anonymised retrospectively collected x-ray fluoroscopy images from patients who underwent LBBAP and had a cardiac MRI. The 3D hybrid guidance system will collect data from the retrospective anonymised X-ray fluoroscopic images, detect the pacing lead and reconstruct the 3D position of the pacing lead and test the accuracy of the 3D hybrid guidance system. ;
