On-screen image-guided lead placement in cardiac resynchronization therapy: Feasibility and outcome in a multicenter setting.

ABSTRACT:

Background

Image guidance to assist left ventricular (LV) lead placement may improve outcome after cardiac resynchronization therapy (CRT), but previous approaches and results varied greatly, and multicenter feasibility is lacking altogether.

Objective

We sought to investigate the multicenter feasibility of image guidance for periprocedural assistance of LV lead placement for CRT.

Methods

In 30 patients from 3 hospitals, cardiac magnetic resonance imaging was performed within 3 months prior to CRT to identify myocardial scar and late mechanical activation (LMA). LMA was determined using radial strain, plotted over time. Segments without scar but clear LMA were classified as optimal for LV lead placement, according to an accurate 36-segment model of the whole heart. LV
