Does non-invasive imaging improve prediction of ventricular arrhythmias in patients with ischaemic cardiomyopathy?
Non-invasive imaging modalities such as nuclear imaging, CMR, and echocardiography may help refine ICD implantation criteria by better predicting ventricular arrhythmias in patients with ischaemic cardiomyopathy.
Hypothesis-generating for imaging-refined ICD criteria in ischaemic cardiomyopathy; prospective trials needed before clinical adoption.
The introduction of the implantable cardioverter defibrillator (ICD) has had a major impact on survival and treatment of patients with ischaemic cardiomyopathy. However, only a third of patients receive appropriate ICD discharges during the first 3 years of follow-up, hence creating opportunities for improvement in patient care as well as for health care costs containment. Therefore, refinement of ICD implantation criteria is needed. Evaluation of pathophysiological substrates related to electrical instability with imaging modalities such as nuclear imaging, cardiac magnetic resonance imaging, and echocardiography might yield important prognostic information. This review discusses the currently available literature regarding the value of these imaging modalities for prediction of ventricular arrhythmias in patients with ischaemic cardiomyopathy.
