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.

  1. 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.

Condition or Disease Intervention/Treatment Phase
  • Device: Drug-Eluting Stents implantation in bifurcation lesions
Phase 4

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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: hydrophilic wire/Drug-Eluting Stents

Will include 100 patients with coronary bifurcation lesions in that they will be treated with stents and in which the technique is used jailed guide.

Device: Drug-Eluting Stents implantation in bifurcation lesions

No Intervention: Non hydrophilic wire/Drug-Eluting Stents

Will include 100 patients with coronary bifurcation lesions in that they will be treated with stents and in which the technique is used jailed guide.non hydrophilic guide.

Outcome Measures

Primary Outcome Measures

  1. No damage: the guidewire suffered no loss of integrity over its entire length [3 years]

  2. Slight damage: the external cover suffered loss of integrity < 2 mm [3 years]

  3. Moderate damage: the external cover suffered loss of integrity > 2 mm [3 years]

  4. Severe damage: visible changes to the inner cover of the guidewire. [3 years]

  5. Fracture: discontinuity at some point along the guidewire [3 years]
