HEAL-HF: A Cardiac Resynchronization Therapy (CRT) Outcomes Study

This study has been terminated.
(Insufficient enrollment)
Information provided by:
Stereotaxis Identifier:
First received: August 29, 2006
Last updated: January 2, 2008
Last verified: January 2008
The literature shows that approximately 40% of individuals who receive a cardiac resynchronization therapy (CRT) device for symptomatic congestive heart failure (CHF) do not have a clinical benefit from the device. The HEAL-HF protocol will compare the outcomes of conventionally placed CRT devices with magnetically placed CRT devices by assessing hemodynamic parameters during the magnetic placement of the left ventricular (LV) lead.

Condition Intervention Phase
Heart Failure, Congestive Procedure: Acute hemodynamic assessment using PV Loops (CD Leycom, The Netherlands) during LV lead placement Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: HEmodynamic Assessment of Optimal Left Heart Lead Placement for Heart Failure Enabled by Magnetic Navigation

Further study details as provided by Stereotaxis:

Primary Outcome Measures:
  • Reduction in end systolic volume (ESV) [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • New York Heart Association (NYHA) Class [ Time Frame: 6 months ]
  • 6 minute walk [ Time Frame: 6 months ]
  • Quality of life (QoL) [ Time Frame: 6 months ]
  • Cardiac-related mortality [ Time Frame: 6 months ]
  • HF-related hospitalizations [ Time Frame: 6 months ]

Estimated Enrollment: 100
Study Start Date: February 2007
Study Completion Date: December 2007
Primary Completion Date: April 2007 (Final data collection date for primary outcome measure)
Detailed Description:
Baseline information will be obtained including QoL, 6-minute walk, and echo measurements. The patient will be randomized to receive a conventionally-placed LV lead or randomized to receive a magnetically-placed LV lead. The magnetic group will have acute hemodynamics assessed during the procedure to evaluate the best response of the left ventricle during pacing. Patients will be followed for 6 months with a re-evaluation of the baseline tests to assess the change in HF symptoms. Adverse events will also be recorded during the follow-up period.
