Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to determine whether MRI guided CRT implantation (using Siemen's software prototype) is superior to standard treatment in terms of CRT response. Data will be collected at enrolment, implant, pre-discharge, 6 weeks and 6 months. The total duration of the investigation will be 6 months.

The primary endpoint will be assessed by calculating the difference in the proportion of responders (\>15% reduction in end systolic volume derived from 2-dimensional transthoracic echocardiogram at 6 months post CRT implant).

MRI guided CRT implantation

Group Type EXPERIMENTAL

Guide CRT Software Prototype

Intervention Type DEVICE

The medical device in the trial is a software programme that allows image fusion of previously acquired MRI images with real-time X-Ray fluoroscopic images in the cardiac catheter laboratory. We are able to use the MRI information to assess the best location to place the left ventricular lead for a CRT device and then superimpose this location onto the real-time X-Ray fluoroscopic images during the left ventricular lead implantation
