About this study
Official title: Corox OTW Steroid LV Lead Monitoring
The objective of this post approval registry is to confirm the long-term safety and effectiveness of the Corox Over-the-wire (OTW) Steroid Left Ventricular (LV) lead as used in conjunction with a BIOTRONK cardiac resynchronization therapy defibrillator (CRT-D). The Corox OTW Steroid LV Lead is capable of providing permanent pacing therapy to the left ventricle in a CRT-D system. The following are the specific objectives to be evaluated during this post-approval registry:
- Long-term effectiveness of the COROX OTW Steroid in providing biventricular pacing
- Safety of the COROX OTW Steroid LV pacing lead
Read the detailed description
This post approval registry enrolled 221 patients from 34 centers. The collection of registry data continued for three years for each enrolled subject. Potential patients were screened by the enrolling physician according to the detailed inclusion and exclusion criteria below.
The specific required visits for this registry are: Enrollment, Three-month, Six month, One-year, Routine Follow-Ups (every subsequent 6 months), Interim follow-ups for Corox OTW Steroid LV lead related visits, and Out of Service visit. Data will be collected at each patient follow-up. The programmed pacing parameters, LV pacing impedance, and LV pacing threshold measurement at 0.5ms pulse width will be obtained. The programming parameters will be set to best suit each patient. If adequate system function, including effective CRT, cannot be obtained, the patient should not be selected for the registry.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Corox OTW Steroid Left Ventricular Lead in people with Congestive Heart Failure, run by Biotronik, Inc. at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 May 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 May 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Long-term Effectiveness of the COROX Over-the-wire (OTW) Steroid in Providing Biventricular Pacing (time frame: All follow-ups for 3 years post implant). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2012; AzTrials last refreshed its copy on 8 Nov 2026.
