Jailed Wire Technique in the Treatment of Coronary Bifurcations Lesions With Stent: Stereoscopic Microscopy Study
Study Details
Study Description
Brief Summary
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.

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.

Outcome Measures
Primary Outcome Measures
- No damage: the guidewire suffered no loss of integrity over its entire length [3 years]
- Slight damage: the external cover suffered loss of integrity < 2 mm [3 years]
- Moderate damage: the external cover suffered loss of integrity > 2 mm [3 years]
- Severe damage: visible changes to the inner cover of the guidewire. [3 years]
- Fracture: discontinuity at some point along the guidewire [3 years]
