Further information from APPRAISE ATP trial reinforce modular remedy strategy with EMBLEM™ Subcutaneous Implantable Defibrillator and EMPOWER™ Leadless Pacemaker
Along with evaluating the security and efficiency of the EMPOWER LP as a standalone pacemaker, the trial evaluated the flexibility of the EMBLEM S-ICD System to efficiently talk a wi-fi request to the LP to ship ATP remedy. Findings from the trial met all pre-specified six-month security and effectiveness endpoints, and demonstrated:
- A serious complication-free price of 97.5% after implantation of the EMPOWER LP.1
- A communication success price of 98.8% from the EMBLEM S-ICD System to the EMPOWER LP.2
- An ATP success price of 61.3%,3 and no affected person requests for deactivation of ATP or bradycardia pacing resulting from ache or discomfort.
- Pacing seize thresholds, which point out secure system fixation throughout the coronary heart, of ‰¤ 2.0 V at 0.4 ms in 97.4% of sufferers.
“We saw excellent overall clinical performance of the mCRM System in this study, including a high rate of communication success from the S-ICD to the leadless pacemaker, and a low rate of major leadless pacemaker complications,” stated Prof.
Additionally introduced at Coronary heart Rhythm 2024 had been outcomes from the APPRAISE ATP medical trial “ a potential, randomized, multicenter research evaluating ATP as a major technique for terminating ventricular tachycardias in major prevention (PP) sufferers (i.e., these with no historical past of spontaneous sustained ventricular arrhythmias). The trial enrolled 2,626 PP sufferers indicated to obtain an ICD at 134 facilities globally and is the most important head-to-head trial of ATP on this affected person group. Within the research, sufferers had been randomized 1:1 to plain transvenous-ICD remedy “ ATP plus an ICD-delivered shock to terminate a ventricular tachycardia “ versus shock solely. Throughout 5 years of observe up, information demonstrated a statistically important, however small absolute first all-cause shock discount in just one% of sufferers per yr. Shock burden, or the variety of shocks skilled by a affected person, was not considerably completely different between the 2 arms, and the overwhelming majority of sufferers within the ATP-plus-shock arm didn’t require ATP remedy.
“Together, data from the MODULAR ATP and APPRAISE ATP trials reinforce the promise of the groundbreaking mCRM System, illustrating a clear path forward for physicians to offer therapies that prevent sudden cardiac death and deliver ATP for the small number of patients who benefit from it,” stated
The corporate anticipates U.S. Meals and Drug Administration approval of the mCRM System in 2025. For extra info on the mCRM System and MODULAR ATP trial, go to www.bostonscientific.com/mcrm. To study extra in regards to the EMBLEM MRI S-ICD System, go to www.sicdsystem.com.

1 Main problems outlined as any complication associated to the EMPOWER LP or its implantation process that leads to system revision, everlasting lack of LP operate, hospitalization, or loss of life.
2 Throughout communication checks, the S-ICD tried to command the LP to ship pacing at a price roughly 10 beats per minute sooner than the affected person’s intrinsic rhythm.
3 ATP success price outlined as terminating ventricular arrhythmia.
