MRI Assessment of Patient Suitability for Cardiac Resynchronization Therapy (CRT)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02728336
Recruitment Status : Suspended (COVID-19)
First Posted : April 5, 2016

NYU Langone Health

Brief Summary:
The goals of this project are to: 1) explore the potential use of magnetic resonance imaging (MRI) data for improved prediction of response to cardiac resynchronization (CRT), and 2) use the MRI-derived data together with a computer model of the cardiovascular system to study the relative roles of different factors in the mechanical effects of dyssynchrony in failure, and in the response (or lack thereof) to CRT.

Condition or disease Intervention/treatment Phase
Cardiac Resynchronization Therapy Magnetic Resonance Imaging (MRI) Procedure: Cardiac MRI Not Applicable

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 110 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: MRI Assessment of Patient Suitability for Cardiac Resynchronization Therapy (CRT)
Actual Study Start Date : November 2014
Estimated Primary Completion Date : August 2024
Estimated Study Completion Date : August 2024

Arm Intervention/treatment
Active Comparator: Heart Failure Patients
patients who are scheduled to undergo clinically ordered CRT for heart failure complicated by dyssynchrony
Procedure: Cardiac MRI
Active Comparator: Control
20 matched control subjects
Procedure: Cardiac MRI

Primary Outcome Measures :
  1. Derivation of score of patient suitability for CRT [ Time Frame: 4 Years ]
    Binary logistic regression and receiver operating characteristic curve (ROC) analyses will be used to assess the utility of baseline (pre-CRT) MRI-derived measures, alone and in combination, for the prediction of response to CRT.
