Fluoroless Conduction System Implant

Sponsor: Imperial College London

Summary

Conduction system pacing is a new way of stimulating the heart using pacemaker wires. Traditional pacemakers stimulate the heart muscle which causes disordered heart beats: the walls of the heart move at different times. This wears down the heart over time. Conduction system pacemakers stimulate the heart's electrical system directly producing natural heart beats that are much less disordered. These pacemakers can be challenging to insert with different heart shapes, sizes and scars. This can increase procedure times and time exposed to xray as pacemakers are inserted using x-rays to guide where the lead is implanted. This study aims to allow conduction system pacemakers to be implanted without the use of normal xray (fluoroscopy). The investigators will create an anatomical shell of the heart using special plastic (mapping) catheters that is inserted within the heart from the groin. The investigators will use a special heart scanning (echo) catheter to see how the pacemaker wire is inserted into the heart muscle. The investigators will use MRI to confirm that the information we collect is accurate. Using this information the investigators will create a protocol to implant a lead that does not require xray, using only the mapping catheter.
