Outcomes
Primary Outcome Measures
Average efficacy of the first ICD shock for all true ventricular tachyarrhythmias
The primary endpoint is the average efficacy of the first ICD shock for all true ventricular tachyarrhythmias of a patient in the observational period. More precisely, the primary endpoint will be determined as the number of true ventricular tachyarrhythmias of a patient (that were efficiently terminated by the first shock delivered by the ICD) divided by the number of true ventricular tachyarrhythmias (treated with at least one ICD shock) of the same patient.
Secondary Outcome Measures
Procedural and safety endpoints
Serious adverse events associated with the implantation procedure
Optional assessment of blood parameters indicating myocardial injury BNP (B-TYPE NATRIURETIC PEPTIDE), Creatinine, Troponin T, CK (Creatin-Kinase), CK-MB (Creatin-Kinase-MB)
Frequency of system revisions at implant, such as repositioning of leads, reprogramming the device to reverse polarity
Total fluoroscopy and implantation time
Follow-Up and efficacy endpoints
All-cause mortality
Cardiac mortality
Arrhythmic mortality
Ventricular tachyarrhythmia conversion efficacy of the ICD shock therapy

5. Study Description
Brief Summary
The purpose of the NORDIC ICD study is to evaluate whether ICD implantation without intra-operative DF testing is non-inferior to ICD implantation with intra-operative DF testing regarding the efficacy of the first ICD shock for the treatment of true spontaneous ventricular tachyarrhythmias.
Detailed Description
The NORDIC ICD study is justified by the need to compare the clinical outcome between patients that did receive defibrillation (DF) testing and those who did not receive DF testing during ICD implantation. The NORDIC ICD study will evaluate the impact of intra-operative DF testing on the long-term ICD first shock efficacy for true ventricular tachyarrhythmias in the observational period. Therefore, the primary analysis of this study will consider all ventricular tachyarrhythmia episodes treated by ICD shock(s) during the trial follow-up period.
Moreover, the Home MonitoringTM system of BIOTRONIK will be used in order to monitor the technical system integrity, device programming and cardiac performance continuously. It supports early information about the occurrence of VT/VF (Ventricular Tachycardia/Ventricular Fibrillation) episodes and corresponding therapies such as ICD shocks. The Home MonitoringTM capability offered by active implants has the potential to detect some of these trends early and thus to offer the possibility to intervene in time for prevention of fatal worsening of cardiac performance.
1077 patients were enrolled and randomized (1:1) in 48 centers in five European countries (Germany, Czech Republic, Denmark, Sweden and Latvia).
