Safety and Performances of the LINEA Cardiac Pacing Lead Optimized for the Implantation in Interventricular Septum

Inclusion criteria (phase I and II):

* 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 an ALIZEA, BOREA or CELEA Single Chamber (SR) or Dual Chamber (DR) pacemaker from MicroPort CRM
* Patient planned for a catheter-guided ventricular pacing lead implantation in the interventricular septum area
* Patient's pacemaker with the remote monitoring functions accepted by the patient and planned to be activated

Exclusion criteria (phase I and II):

* Patient planned for a device upgrade, or a device or a lead replacement
* Patient with a congenital heart disease, hypertrophic cardiomyopathy or infiltrative 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 having a contraindication for cardiac pacing system implantation (i.e. patient implanted with a defibrillator, patient for whom a single dose of steroid eluted by the pacing lead (e.g., dexamethasone sodium phosphate) is contraindicated, 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)
* Patient with a life expectancy of less than 2 years
* 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
