NCT03014180

Brief Summary

The purpose of the LEVEA study is to assess the performances of a new automatic left ventricular auto threshold (LVAT) algorithm (In-Clinic LVAT algorithm) when used by physicians during in-hospital follow-up.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Successful"In-Clinic LVAT" Test

    The success rate is defined as the equivalence between the value measured by the algorithm and the measure obtained manually by the physician on 5 identified pacing vectors during the visit among at least 231 LV tests.

    0-3 months post inclusion

Secondary Outcomes (5)

  • Percentage of Accurate "In-Clinic LVAT" Test Assessed by an Independent Reviewer

    0-15 days post inclusion

  • Percentage of Successful of "In-Clinic LVAT" Test at M0 Visit

    0-15 days post inclusion

  • Percentage of Successful "In-Clinic LVAT" Test at M1 Visit

    1-3 months after first visit

  • Percentage of Eligible Subjects to LVAT Feature

    0-3 months post inclusion

  • Safety of the LVAT Algorithm

    0-3 months post inclusion

Study Arms (1)

"In-Clinic LVAT"

EXPERIMENTAL

All subject prior to study enrollment has been implanted with a CRT-D device. During follow-ups, under the supervision of the physician, the algorithm embeded in the device is activated with a password. The feature is deactivated at the end of each follow-up.

Device: "In-Clinic LVAT"

Interventions

Algorithm offers automatic threshold measurement of differents vectors of left ventricular stimulation.

Also known as: Activation of an algorithm in CRT-D device
"In-Clinic LVAT"

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject already implanted (de-novo, upgrade or replacement) according to the relevant ESC Guidelines \[1\]:
  • With IS1 Platinium SonR CRT-D (models 1811, 1841, CE-marked) for maximum of 5 days or;
  • With IS4 Platinium SonR CRT-D (model 1844, CE-marked).
  • Right atrial, right and left ventricular leads must be implanted. Only bipolar and quadripolar for Left Ventricular lead.
  • Reviewed, signed and dated informed consent.

You may not qualify if:

  • Subject included in another clinical study that could confound the results of this study;
  • Malfunction or dislodgment of right atrial, right and left ventricular implanted leads;
  • Subject diagnosed with permanent atrial fibrillation;
  • Known pregnancy;
  • Minor age;
  • Under protection or guardianship;
  • Unavailability for scheduled follow-up or refusal to cooperate
