Understanding Outcomes With the EMBLEM™ S-ICD in Primary Prevention Patients With Low Ejection Fraction

Overview

Información sobre este estudio

This study assesses the 18-month incidence of inappropriate shocks in subjects implanted with the EMBLEM Subcutaneous Implantable Defibrillator (S-ICD) for primary prevention of sudden cardiac death. Devices are to be programmed with zone cutoffs at 200 bpm and 250 bmp in order to mimic the programming settings for transvenous ICDs in the MADIT RIT study. The incidence of inappropriate S-ICD shocks will be compared to the incidence of inappropriate shocks observed in the MADIT RIT study.

Elegibilidad para la participación

Los requisitos de elegibilidad de los participantes incluyen la edad, el sexo, el tipo y el estadio de la enfermedad, y los problemas de salud o tratamientos previos. Las pautas difieren de un estudio a otro e identifican quiénes pueden o no pueden participar. No hay garantía de que cada persona elegible que desee participar en un ensayo se inscribirá. Comunícate con el equipo del estudio para analizar la elegibilidad del estudio y la posible participación.

Inclusion Criteria:

  • Patient with ischemic or non-ischemic heart disease who meets current guidelines for ICD therapy and intends to undergo a de novo implant procedure for an EMBLEM™ S-ICD (or newer generation BSC S-ICD)
  • Left ventricular ejection fraction ≤ 35%
  • A passing EMBLEM™ S-ICD (or newer generation BSC S-ICD) screening ECG
  • Patient ≥ 21 years of age willing and capable of giving informed consent
  • Patient willing and capable of complying with follow-up visits

Exclusion Criteria:

  • Patient with a history of spontaneous sustained VT or VF
  • Patient with bradycardia pacing indication
  • Patient eligible and scheduled for cardiac resynchronization implant
  • Patient with a previous S-ICD or a previous transvenous pulse generator (pacemaker or defibrillator)
  • Patient in NYHA Class IV documented in the medical records within 90 days before enrollment
  • Patient with life expectancy shorter than 18 months due to any medical condition (e.g., cancer, uremia, liver failure, etc…)
  • Patient receiving hemodialysis within 180 days before to enrollment
  • Patients unable to give consent in person, including patients unable to read or write
  • Patient who is known to be pregnant or plans to become pregnant over the course of the trial
  • Patient unwilling or unable to cooperate with the protocol
  • Participation in concurrent clinical study without prior approval from Boston Scientific
  • Medical status (e.g., hemodynamic conditions ) of the patient doesn't allow programming devices with a conditional shock zone at 200 bpm and a shock zone at 250 bpm, in the judgment of the implanting physician and/or according to (inter) national guidelines

  • The UNTOUCHED study will assess the safety and efficacy of the subcutaneous implantable cardioverter defibrillator (S-ICD) in the most common cohort of patients receiving ICDs. The primary goal is to evaluate the inappropriate shock (IAS)-free rate in primary prevention patients with a reduced ejection fraction (EF) and compare with a historical control of transvenous ICD patients with similar programming.
