Description

Inclusion criteria (phase I):

  • Patient indicated for cardiac pacing according to the most recent guidelines from the European Society of Cardiology (ESC)
  • Patient planned for a de novo implantation of any Single Chamber (SR) or Dual Chamber (DR) CE marked pacemaker
  • Patient planned for a catheter-guided implantation in the interventricular septum area
  • Patient planned for the implantation of any CE marked ventricular pacing lead compatible with the FLEXIGO delivery catheter
  • Patient reviewed, signed and dated the Informed Consent Form (ICF)

Inclusion criteria (phase II):

  • Patient indicated for cardiac pacing or CRT according to the most recent guidelines from the ESC
  • Patient planned for a de novo implantation of any SR or DR CE marked pacemaker, or any CE marked CRT-D
  • Patient planned for a catheter-guided implantation in the interventricular septum area
  • Patient planned for the implantation of any CE marked ventricular pacing lead compatible with the FLEXIGO delivery catheter
  • Patient reviewed, signed and dated the ICF

Exclusion criteria (phase I):

  • Patient planned for a device upgrade, or a device or a lead replacement
  • Patient with a congenital heart disease
  • Patient with significant hypertrophic cardiomyopathy, cardiac amyloidosis or obstructive hypertrophic cardiomyopathy
  • Patient with a Left Ventricular Ejection Fraction (LVEF) ≤ 35%
  • Patient already enrolled in another clinical investigation that could confound the results of this clinical investigation (e.g., clinical investigations involving intra-cardiac device)
  • Patient implanted despite a contraindication for cardiac pacing system implantation (i.e. patient implanted with a defibrillator, patient contraindicated for a single dose of 310 μg of dexamethasone sodium phosphate, patient implanted with a tricuspid replacement heart valve, with prior tricuspid valve intervention or with a significant tricuspid valve disease that may lead to future replacement heart valve surgery)
  • Minor age patient (i.e. under 18 years of age)
  • Incapacitated patient, under guardianship, kept in detention, refusing to cooperate or not able to understand the purpose of this clinical investigation
  • Non-menopausal women

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Absence of Unanticipated Serious Adverse Device Effect (USADE) related to FLEXIGO delivery catheter
Time Frame: 72 hours after implantation
Any event caused by use of the FLEXIGO delivery catheter or any accessory packaged with the catheter, will be considered as an ADE related to the FLEXIGO delivery catheter. The primary endpoint evaluation will be based on Sponsor assessment of safety events, based on investigational site reporting.
72 hours after implantation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Implantation success rates
Time Frame: During implantation

- Implantation success rate with FLEXIGO delivery catheter: Proportion of lead successfully implanted at the interventricular septum with use of the FLEXIGO delivery catheter.

- Left Bundle Branch Area Pacing (LBBAP) implantation success rate with FLEXIGO delivery catheter: Proportion of lead successfully implanted at the interventricular septum with use of the FLEXIGO delivery catheter and fulfilling LBBAP success criteria according to the operator's decision.

- LBBAP implantation success rate (overall): Proportion of lead successfully implanted at the interventricular septum with use of any material and fulfilling LBBAP success criteria.
During implantation
Implantation time
Time Frame: During implantation
Total procedural time and total fluoroscopic time documented per type of cardiac device implanted and per model of catheter used.
During implantation
Implantation usability
Time Frame: During implantation
Implantation usability of the FLEXIGO delivery catheter documented through handling scores based on a specific questionnaire addressed to the operator after implantation.
During implantation
Serious Adverse Device Effect (SADE) rate related to FLEXIGO delivery catheter or the slitter
Time Frame: 72 hours after implantation
Proportion of SADE related to the FLEXIGO delivery catheter or the slitter.
72 hours after implantation
Left Bundle Branch Area Pacing (LBBAP) implantation success rate per indication (cardiac pacing and CRT) and per ventricular pacing lead model
Time Frame: During implantation

- LBBAP implantation success rate with FLEXIGO delivery catheter (documented in cardiac pacing and CRT-D populations separately): Proportion of lead successfully implanted at the interventricular septum with use of the FLEXIGO delivery catheter and fulfilling LBBAP success criteria according to the operator's decision.

- LBBAP implantation success rate (overall, and documented in cardiac pacing and CRT-D populations separately): Proportion of lead successfully implanted at the interventricular septum with use of any material and fulfilling LBBAP success criteria according to the operator's decision.
