Subcutaneous Implantable Defibrillator

Level Up with AST 2.0

The EMBLEM MRI S-ICD Automated Screening Tool (AST) takes patient screening to the next level by incorporating your feedback to increase efficiency and usability.

  • Integration with the Heart Connect™ System
  • On-Screen Instructions
  • Progress Indicator During Capture of ECG
  • Drop-Down List for Optional Postures
  • Multiple Sternal Lead Positions Within a Single Session
  • Reasons for Vector Failure
  • Filtered Signal Can Now Be Included on Report
  • Selectively Export Sessions

AST 2.0 Now Available through the LATITUDE™ Programming System, Model 3300

Applies the Vector Select algorithm that is used by the S-ICD to sense the cardiac signal designed to more closely represent
S-ICD device performance.1

The Evolution of S-ICD Screening

Screening for S-ICD has continued to evolve to remove subjectivity while increasing efficiency and usability.  

Which Patients Should Be Screened for an S-ICD?

All ICD-indicated patients without a pacing need should be considered for an S-ICD.



Patient Comorbidities


TV-ICD Required3,4

TV-ICD Considered3,4

Evaluating Need for Brady Pacing5-7

Brady pacing indication at implant




No current pacing indication, but has 1 or more of the following:

  • H/O CABG surgery
  • H/O atrial fibrillation
  • Age > 80
  • PR interval > 200 ms



No pacing indication at implant and age < 80




High Risk for TV Lead Failure8

Life expectancy > 8 years




High Risk for Infection9 H/O device infection




Prosthetic heart valve



On dialysis or renal insufficiency







Other risk factors:

  • COPD
  • Corticosteroid use
  • Oral anticoagulation
  • Class II-IV heart failure
  • Chronic skin disorder
  • Malignancy



High or Low Risk for ATP10,11

Ischemic or non-ischemic heart failure or ICD-indicated patient with NO history of recurrent sustained monomorphic VT



ICD-indicated patient WITH a history of recurrent sustained monomorphic VT amenable to ATP therapy
