Why the study?
Does a subcutaneous left dorsolateral array anode improve defibrillation efficacy compared to or in addition to a standard active can ICD in patients undergoing ICD placement?
Population
108 patients undergoing implantable cardioverter defibrillator (ICD) placement (68 in ACAT I, 40 in ACAT II)
Comparison
Subcutaneous left dorsolateral array anode used… vs Standard left pectoral active can anode alone
Design
RCT, Prospective randomized
Follow-up
Intraoperative

Supports array lead use to lower DFTs at ICD implant; extends randomized data on lead configurations beyond active can.
Does a subcutaneous left dorsolateral array anode improve defibrillation efficacy compared to or in addition to a standard active can ICD in patients undergoing ICD placement?
A left pectoral subcutaneous array lead, used instead of or in addition to an active can ICD, significantly lowers defibrillation thresholds and impedance.
