Jailed Wire Technique in the Treatment of Coronary Bifurcations Lesions With Stent: Stereoscopic Microscopy Study

The aims of this study are: 1) To identify more resistant the guidewire type to the retrieval maneuvers after the jailing. 2\) 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.
