Filter by:Phase I: For the Phase I portion, there will be up to 15 patients treated with SABR and followed for 6 months post-treatment to ensure no significant acute grade 3 or 4 toxicity from SABR treatment. Efficacy as defined below will also be assessed. Following this Phase I lead-in, results will be presented to the FDA for review. Only upon favorable analysis by the FDA committee, and with written explicit permission, will the Phase II randomized portion ensue. This is to act as a safety and efficacy safeguard and has is addressed more thoroughly in the Statistical Analysis Plan of this protocol. Phase II: A 1:1 randomized Phase II portion with 25 patients in each arm assigned to SABR or current practice (standard of care; Figure 3). Standard of care is defined as nationally recognized appropriate next treatment strategies for medical and catheter-ablation refractory structural cardiac VT that is assessed and judged appropriate for the patient by his/her treating cardiologist. This includes repeat catheter ablation (intravascular and/or epicardial catheter ablation), placement of left-ventricular assist device (LVAD), heart transplant, or further medical management (e.g. antiarrhythmic drug modulation/continuation). Randomization will be performed through the Clinical Trial Conduct (CTC) website.
Prospective, multi-center (2-3 sites), non-randomized, open label, single arm 3 phase study: 1. Phase 1 or Evaluation Phase: Where the KODEX-EPD System will be used to exclusively monitor the entire implantation procedure; the KODEX-EPD system will not be used for guidance during the lead implantation workflow. 2. Phase 2 - KODEX-EPD-assisted Phase: Where the KODEX-EPD system will be used for cardiac imaging acquisition, guidance during lead implantation in conjunction with fluoroscopic imaging 3. Phase 3 - KODEX-EPD-guided Phase: Where the KODEX_EPD System will be used as the leading imaging modality during the lead implantation workflow. Fluoro can be used; - up until the part of the lead implantation workflow that is the scope of this investigation. - As a bailout, when the operator declares failure to attempt.
The purpose of this study is to evaluate a novel non-invasive cardiac electric imaging methodology for localizing and imaging cardiac electrical activity from body surface electrocardiographic recordings in patients with ventricular tachycardia (VT). Using non-invasive means will increase our ability to correctly diagnose cardiac abnormalities, and aid ablation of cardiac arrhythmias, offering enhanced performance to what currently exists.
The purpose of this study is to investigate non-linear heart rate variability indexes as predictors of the incidence of cardiac arrhythmias in patients undergoing cardiac surgery, including coronary artery bypass graft (CABG) and valvular surgery.
