- Population Health Research Institute
- Brief Summary
The purpose of the study is to compare standard, single chamber transvenous ICD to sub-cutaneous ICD in occurrence of perioperative and long term device related complications and failed appropriate clinical shocks and arrhythmic death.

Group Intervention Description Subcutaneous ICD Implantable Cardioverter Defibrillator Patient will receive a subcutaneous implantable cardioverter defibrillator (Boston Scientific EMBLEM) Transvenous ICD Implantable Cardioverter Defibrillator Patient will receive a single-chamber, transvenous implantable cardioverter defibrillator (from any manufacturer) which as the capability for remote monitoring.
- Primary Outcome Measures
Name Time Method Additional safety composite 6 months post-ICD implantation This composite includes:
Device-related infection requiring surgical revision; Significant wound hematoma (requiring evacuation or interruption of oral anticoagulation); Myocardial infarction; Stroke; Death;Composite of lead-related perioperative complications 6 months post-ICD implantation This composite includes:
Hemothorax or pneumothorax; Cardiac perforation, tamponade, pericardial effusion or pericarditis; Lead dislodgement or loss of pacing/sensing requiring revision; New moderate-severe or severe tricuspid insufficiency (3+ or 4+); Ipsilateral upper extremity deep venous thrombosis.
- Secondary Outcome Measures
Name Time Method Late device-related complications Greater than 6 months post-ICD implantation The following complications will be measured by their presence or absence; they will be presented as individual complications and also as a composite of late device-related complications:
* Lead dislodgement or fracture; or loss of adequate sensing or pacing
* Device-related infection
* Pericarditis or pericardial effusion
* New severe tricuspid insufficiency
* Ipsilateral upper extremity deep venous thrombosis
* Need to revise dialysis access
* Need to revise ICD or lead for any reason
* Non-systemic embolism
* Pulmonary embolism
* Wound dehiscence or disjunction
* Allergic reaction to ICDAll-cause mortality 6 months post-ICD implantation Efficacy outcome
Total device-related complications Greater than 6 months post-ICD implantation This is a composite of:
all components of the primary and secondary safety outcomes, and late device-related complications.Occurrence of failed appropriate shock or arrhythmic death 6 months post-ICD implantation Efficacy outcome
Patient Health Survey as measured by Short Form Health Survey (SF36) Baseline and 6 months post-ICD implantation Patient health will be assessed by a generic instrument, the Short Form Health Survey (SF36). This survey provides scores for each of the eight health domains and psychometrically-based physical component summary and mental component summary scores.
Any inappropriate ICD therapy shock 6 months post-ICD implantation Efficacy outcome
Provincial healthcare payer health economics analysis 6 months post-ICD implantation A formal health economics analysis will be completed as part of this study, using the perspective of a provincial healthcare payer. Procedural costs will be obtained from the Ontario schedule of benefits and the cost of device-implantation will be taken from existing, local case-costing data. The cost-effectiveness analysis will take into consideration any differences in survival, complication rates and resource utilization. Sensitivity analyses will be done, varying the price of the S-ICD, in order to generate cost-acceptability curves.
Hospital, emergency department or clinic visits for ICD therapy, device-related complications, arrhythmia or heart failure 6 months post-ICD implantation Efficacy outcome. Hospital, emergency department or clinic visits for ICD therapy (shocks or anti-tachycardia pacing, both appropriate and inappropriate), device-related complications, arrhythmia or heart failure
Patient Acceptance of ICD as measured by Florida Patient Acceptance Survey (FPAS) 1 month and 6 month post-ICD implantation Patient acceptance of ICD will be measured using the Florida Patient Acceptance Survey (FPAS).
