Left Bundle Branch Area Pacing (LBBAP) Monitoring Assistant: Evaluation of Portable ECG Solution

To evaluate the capability to monitor LBB success criteria with the use of a Smart ECG system (ECG monitor, 12 leads ECG cable, ECG viewer software ) during a cardiac device implantation involving the placement of a pacing lead in interventricular septum area

About this study

The clinical investigation aims to support physicians with a portable and easy to use solution to display ECG and to provide automatic calculation of key ECG indicators (Left Ventricular Activation time (LVAT) and V6-V1 interval) for LBB implantation procedure. This allows physicians to concentrate on lead placement with the benefice from immediate ECG measurements thanks to the automatic software.

The Smart ECG system is class IIA device and it is composed of:

  • CE-marked Smart ECG, Class IIa medical device (rule 10 Annex VIII of MDR)
  • ECG viewer Software (HookUp SmarV2) (providing 12 lead ECG display + automatic interval measurements + shadow plot for QRS visualization) Class IIa medical device (rule 11 Annex VIII of MDR).
  • CE -marked 12 leads ECG cables radiotransparent and defibrillation proof (Class I device)
  • Commercial PC used in combination with the devices under evaluation

The study is a pre-market, non-pivotal study: HookUp Smart V2 software is a non-implantable Class IIA device, with no interaction with the human body and the demonstration of conformity with general safety and performance requirements is based on the results of non-clinical testing methods alone (as article 61(10) from MDR.

  • Subject signed and dated the ICF

Exclusion criteria

  • Incapacitated subject or under guardianship
  • inability to understand the purpose of the study
  • Minor subjects
  • Non menopausal women
  • Patients implanted with other electrically active non cardiac devices.

Treatment and study plan

LBBAP implant

Device

Use of Smart ECG system during the LBB implant

Primary outcomes

  1. Capability to monitor LBB success criteria with the use of Smart ECG system

    Time frame: baseline/ procedure

    Proportion of investigators providing an overall favorable assessment (assessed "GOOD or ACCEPTABLE") on a four- point scale (GOOD, ACCEPTABLE, POOR, VERY POOR) on the use of Smart ECG system to achieve LBB area pacing.

Secondary outcomes

  1. The accuracy of the two measurements (LVAT and V6-V1)

    Time frame: baseline/ procedure

    The accuracy of the two measurements (LVAT and V6-V1) during the final LBB lead position (LBBAP) will be assessed separately by comparing manual and automatic methods.

  2. Identification of LBB transitions

    Time frame: baseline/ procedure

    Concordance between EP and Smart ECG for the identification of LBB transitions (non-selective to selective or non-selective to LVSP, during threshold test at final lead position)

  3. Type of LBB capture

    Time frame: baseline/ procedure

    Concordance of type of LBB capture as determined by EP vs Smart ECG signals (LBBAP, likely LBBAP, LVSP) - based on centralized blinded review of EP annotated screenshot and Smart ECG recordings

  4. Signal quality analysis

    Time frame: baseline/ procedure

    Comparison of Smart ECG versus EP signal quality analysis (signal to noise ratio, frequency analyses)

  5. Investigator's satisfaction

    Time frame: baseline/ procedure

    Investigator's satisfaction questionnaire about using Smart ECG system during the full procedure (i.e .setting the system for the procedure, monitoring lead progression, assessing pacing capture)

  6. Safety reporting

    Time frame: baseline/ procedure

    To report any SADE, ADE, DD occurred during the investigational procedure
