This study is designed to show that a new lead, which paces the left bottom chamber (left ventricle) of the heart, is safe. Using a lead on the left side of the heart has been shown to potentially improve heart failure symptoms. The shape and size of this new lead may make it a good choice for patients or physicians.

Detailed Description:
This study is a prospective, multi-center, non-randomized design trial. All consented patients who meet all inclusion and no exclusion criteria may receive the investigational lead. The study design has statistical power to show safety at one-month after implant.

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Cardiac Resynchronization Therapy (CRT)/Cardiac Resynchronization Therapy-Defibrillator (CRT-D) indications according to the European Society of Cardiology/American College of Cardiology/American Heart Association (ESC/ACC/AHA) guidelines
  • On optimal medical treatment according to investigator opinion
  • Indicated for implantable cardioverter defibrillator (ICD) if CRT-D is implanted
  • Patient consent
  • Geographically stable

Exclusion Criteria:

  • Left Ventricular (LV) lead implant attempt in last 30 days
  • Unstable angina or acute myocardial infarction (MI) in past 30 days
  • Coronary artery bypass graft (CABG) or percutaneous transluminal coronary angioplasty (PTCA) in past 90 days
  • Contraindicated for transvenous pacing
  • Heart transplant
  • Contraindicated for less than 1 milligram (mg) dexamethasone acetate
  • Enrolled or intends to participate in concurrent drug and/or device study which would confound results
  • Life expectancy shorter than duration of the study
  • Exclusion criteria required by local law
  • Unable to tolerate urgent thoracotomy
