Plain English Summary

What is this study?

  • • Testing a new treatment for cardiovascular diseases
  • • NA - 218 participants
  • • 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

Who can take part?

  • • Ages 18 Years and over
  • • Diagnosed with cardiovascular diseases

Where?

  • • London - Guys and St Thomas NHS Foundation Trust

This is a simplified summary. Always discuss with your doctor before making any decisions.

About This Trial

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).
