Patients with heart failure, reduced ejection fraction, and signs of myocardial dyssynchrony have a poor prognosis. Cardiac resynchronization therapy is a proven therapeutic modality that reduces symptoms of heart failure as well as morbidity and mortality in these patients. Better identification of patients who could benefit from cardiac resynchronization therapy is an important factor because a significant percentage of patients do not experience clinical improvement after CRT implantation. Cardiac magnetic resonance is a useful, non-invasive, sophisticated diagnostic tool that can provide useful information on the aetiology of heart failure and the severity of mechanical dyssynchrony of the left ventricle. It helps evaluate the myocardial scar burden, which can predict a possible unsatisfactory response to therapy and helps improve clinical outcomes by enabling optimal positioning of the LV lead. Cardiac magnetic resonance in patient follow up after CRT implantation is proven to have significant clinical value. Conclusion: Cardiac magnetic resonance is a non-invasive imaging modality that can provide better identification of the patients who could respond well to cardiac resynchronization therapy. By providing valuable information about the severity of mechanical dyssynchrony, the myocardial scar burden and optimal positioning of the LV lead, it is useful in improving clinical outcomes after CRT implantation.

“…However, mechanical dyssynchrony can also be measured using cardiac magnetic resonance (CMR). CMR can provide high-resolution strain images to assess dyssynchrony with reduced inter-observer variability 59). The myocardial tagging technique is the most commonly used, but the recently developed cine displacement encoding with stimulated echoes methodology provides accurate assessment of myocardial displacement and circumferential strain with higher resolution 59).…”

The myocardial tagging technique is the most commonly used, but the recently developed cine displacement encoding with stimulated echoes methodology provides accurate assessment of myocardial displacement and circumferential strain with higher resolution 59). However, the techniques for assessing dyssynchrony with CMR still remain mostly for research purposes, and large, prospective, multicenter trials of clinically feasible external validation have not been undertaken to evaluate their performance.…”

Cardiac resynchronization therapy (CRT) has revolutionized the care of the patients with heart failure with reduced ejection fraction and electrical dyssynchrony. The current guidelines for patient selection include measurement of left ventricular systolic function, QRS duration and morphology, and functional classification. Despite consistent and increasing evidence supporting CRT use in appropriate patients, CRT has been underutilized. Notwithstanding the heterogeneous definitions of non-response, more than one-third of patients demonstrate a lack of echocardiographic reverse remodeling or poor clinical outcome following CRT. Since the causes of this non-response are multifactorial, it will require multidisciplinary efforts to overcome including optimal patient selection, procedural strategies, as well as optimizing post-implant care in patients undergoing CRT. The innovations of novel pacing approaches combined with advanced imaging technologies may eventually offer a personalized CRT system uniquely tailored to each patient's dyssynchrony signature.
