S-ICD is Guideline Recommended

 
The S-ICD is now guideline recommended for patients at high risk of infection, inadequate venous access, and any patient without a pacing indication – the majority of ICD indicated patients.1
75% of ICD-Indicated Patients Have ≥1 Comorbidity Associated with Device Infection2-4
70% of DR & VR ICD Patients Under 75 Have No Pacing Indication at Implant5-6
61% of Patients May Have Venous Stenosis Following Initial Device Implantation7
   

UNTOUCHED Acute Outcomes

Hypothesis

The incidence of inappropriate shocks in primary prevention, LVEF ≤ 35% patients will be non-inferior to the rate in transvenous ICD patients with similar programming observed in MADIT-RIT Arms B and C.

Study Design

  • Follow-up for 18 months
  • Device programming with a conditional zone of 200 bpm and a shock zone of 250 bpm
  • Primary endpoint of inappropriate shock-free rate at 18 months
  • Secondary endpoints of all cause shock-free rate at 18 months and system and procedure complications at 30 days
 

Acute Outcomes

Conversion efficacy and complication-free rates remain high, consistent with historical S-ICD studies.

TV-ICD Lead Complications in the Real World

The transvenous lead is the most common source of complications in a TV-ICD system. Data from over 40,000 patients from the OptumLabs Data Warehouse demonstrated that the incidence of mechanical and infectious complications of transvenous leads over long-term follow-up is much higher in the real world than in clinical studies. 
3-4% of patients with TV-ICD suffer lead malfunctions in the first year of implant.9
About 25% mechanical failure rate for TV-ICD at 10 years.9
4% infection rate for TV-ICD at 10 years9

Analysis of MADIT RIT Data10

A new analysis of data from MADIT RIT demonstrates patients are more likely to develop complications from transvenous leads than they are to benefit from ATP.

  • There is a statistically significant reduction in ATP with contemporary programming, suggesting that many VTs are self-terminating and earlier interventions may lead to an overestimation of the value of ATP. 
  • Despite the use of significantly more ATP in the conventional programming arm of MADIT RIT, there was no reduction in the final shock rate when compared to the contemporary programming arms.

SMART Pass Significantly Reduces IAS

 
Real-world LATITUDE data for 1,984 patients demonstrated the annual rate of inappropriate shocks (IAS) went down to 4.3% when SMART Pass was enabled. This is a reduction of over 67% compared to the IAS rate seen in the original IDE study.11

PRAETORIAN: S-ICD vs. TV-ICD

PRAETORIAN is the first prospective, randomized, head-to-head, non-inferiority clinical trial that compares S-ICD to TV-ICD. The trial followed 850 patients at 40 centers across Europe and the United States. Results are expected in 2020.
