Model 4296 Left Ventricular (LV) Lead Study (4296)

This study has been completed.
Information provided by:
Medtronic Cardiac Rhythm and Heart Failure Identifier:
First received: June 23, 2009
Last updated: December 1, 2010
Last verified: June 2010
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.

Experimental: Model 4296 LV Lead
Non-randomized study
Device: Pacing Lead (Model 4296 LV Lead)
Implant and follow-up of study device

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.

  • 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
