This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a new way to position a subcutaneous implantable cardioverter-defibrillator (S-ICD)—a small device placed under the skin to prevent sudden cardiac death—using ultrasound imaging instead of X-rays during surgery. Researchers want to see if ultrasound can help doctors place the device in the best position, and whether they can calculate an important safety score called the PRAETORIAN score during the procedure rather than after.
Currently, doctors use X-rays to plan and confirm device placement, which happens before or after implantation. This trial could make implantation safer by allowing doctors to identify high-risk patients and adjust positioning in real time, before testing whether the device will successfully stop dangerous heart rhythms.

You will undergo the standard S-ICD implant procedure, but doctors will also use ultrasound to determine the ideal device position and take additional measurements during surgery to calculate a safety score beforehand. You will have a standard chest X-ray on the day after surgery to confirm proper placement. The study involves no extra procedures beyond what is normally done for this implant.
