Lb-456087-1 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 PRAETORIAN score was developed to predict the defibrillation success of the subcutaneous ICD (S-ICD), based on anatomical device position on a chest X-ray, as an alternative to defibrillation testing (DFT). Although only retrospectively validated, the score is currently being used in both research and clinical practice. The prospective randomized PRAETORIAN-DFT trial investigates whether the PRAETORIAN score is non-inferior to the DFT in regard to predicting first shock efficacy. The current analysis is the first prospective validation of the PRAETORIAN score for defibrillation success in induced ventricular arrhythmias.
