简要总结

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).
