<qa>  What is the effect of AdreViewTM imaging on the decision of implantable cardioverterThis is an event-driven Phase IIIb, multicentre, randomised, clinical study to demonstrate the efficacy of AdreViewTM imaging for appropriately guiding the decision of implantable cardioverter defibrillator ICD implantation, in New York Health Association NYHA class II and III heart failure patients with 25left ventricular ejection fraction LVEF35, and in particular, for identifying patients who are at low risk for sudden cardiac death and who would not benefit, or may suffer harm, from implantation of an ICD device.
