About this study
Official title: Jailed Wire Technique in the Treatment of Coronary Bifurcations Lesions With Stent: Prospective Randomized Study With Stereoscopic Microscopy
The aims of this study are: 1) To identify more resistant the guidewire type to the retrieval maneuvers after the jailing.
- To determined anatomic and technical factors influencing the induced damage in the guidewire.
Design of the study: prospective randomized study to compare 2 types of guidewire: hydrophilic and no hydrophilic. Patients and methods: Two hundred patients with bifurcation coronary lesions will be included. All of then will be treated by provisional side-branch stenting using the jailed wire technique. One hundred patients will be randomized to hydrophilic wires and another 100 patients to non-hydrophilic wires.
Read the detailed description
The percutaneous approach of bifurcation lesions is a complex procedure; when the stent is implanted at main vessel, a closure of the side-branch may occur. The re-wiring of the side-branch in these conditions may be difficult or even impossible. To facilitate the re-wiring maneuvers the operators use the jailed wired technique. For this technique a guide-wire is introduced in the side-branch before main vessel stent implantation; after the stent deployment the wire remains jailed between the vessel wall and the metallic structure of the stent. If the side-branch became occluded, this wire is a good landmark of it is position, facilitating the access with a new wire. However, the rupture of the wire has been described in some cases, during the retrieval maneuvers.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Drug-Eluting Stents implantation in bifurcation lesions in people with Coronary Health Disease, run by Maimónides Biomedical Research Institute of Córdoba at 1 site in Spain.
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 8 inclusion and 4 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 6 Apr 2016. 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 Spain. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
No damage: the guidewire suffered no loss of integrity over its entire length (time frame: 3 years). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02516891, which also lists 1 linked publication.
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 6 Apr 2016; AzTrials last refreshed its copy on 8 Nov 2026.
