Effectiveness and Costs of ICD Follow-up Schedule with Telecardiology

Laurence Guédon-Moreau, European Heart Journal 2013

Study Design

  • Randomized, interventional, multicenter study
  • Compares the safety of continuous BIOTRONIK Home Monitoring versus conventional ambulatory follow-up of ICDs
  • 433 patients at 43 centers in France

Key Result 1

Remote follow-up with BIOTRONIK Home Monitoring® is as safe as conventional ambulatory follow-up.

Proportion of Patients

Clinical Relevance

  • The ECOST study shows that BIOTRONIK Home Monitoring of ICDs is a safe alternative to in-office follow-ups. It positively impacts patient outcome, specially when it comes to reducing the risk of inappropriate shocks – a very unpleasant experience
  • The value of BIOTRONIK Home Monitoring for continuous remote monitoring, through its daily transmissions, is essential for clinics to better manage their patients health condition

Study Objective
  • Examination of the long-term safety and effectiveness of home monitoring (HM) of implantable cardioverter defibrillators
1° Endpoints
  • The proportion of patients who experienced ≥ 1 MAE, including death from any cause, cardiovascular and procedure or device related MAE
2° Endpoints
  • Appropriate and inappropriate shock deliveries
  • ICD capacitor charges
  • Impact on battery longevity
