Evidence from Four Randomized Studies

First results of the randomized PRAETORIAN-DFT trial
Prospective validation of the PRAETORIAN score for prediction of defibrillation test success after subcutaneous ICD implant.
The findings from this first analysis demonstrate that a low (<90) PRAETORIAN score is 99% predictive for a successful DFT and a high (≥90) PRAETORIAN score is the strongest predictor for DFT-failure (odds ratio of 34 ).10
While the study investigators concluded their presentation by stating that the PRAETORIAN score could be used as an alternative for DFT in cases when DFT-testing is not possible or desirable, omitting DFT’s in S-ICD implants cannot be advised until the full PRAETORIAN-DFT results are available.
