Estimated Enrollment: 1000
Study Start Date: May 2004
Primary Completion Date: March 2007 (Final data collection date for primary outcome measure)
Detailed Description:
The CRT RENEWAL Registry aims to characterize patient demographics and clinical attributes at enrollment and overall event rates as defined by heart failure decompensation, heart failure hospitalization, death, and ventricular arrhythmic events. The registry will also assess clinical outcomes including quality of life (QOL), physical activity habits, and events rates, along with device diagnostics such as Activity Log Index and heart rate

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Standard CRT population

Inclusion Criteria:

  • Patients who meet current indications for the CONTAK RENEWAL® family of CRT-P or CRT-D devices
  • Patients who receive either transvenous Guidant manufactured ventricular leads or non-Guidant epicardial leads
  • Patients who have had an ejection fraction measured within six months of enrollment
  • Patients who sign and date a Patient Informed Consent form at the enrollment visit
  • Patients who remain in the clinical care of the enrolling physician in approved centers

Exclusion Criteria:

  • Patients who are expected to receive a heart transplant during the duration of the registry
  • Patients who currently have or who are likely to receive a tricuspid valve prosthesis
  • Patients who are currently enrolled in another observational registry or investigational study that would directly impact the treatment or outcome of the CRT RENEWAL Registry. Each instance will be brought to the attention of Guidant's Clinical Application Research Studies (CARS) Department to determine eligibility
