Two-stent vs Provisional Stenting Techniques for Patients With Complex Coronary Bifurcation Lesions

Not Applicable

Completed

• Conditions: Coronary Artery Disease

• Registration Number: NCT02284750
• Lead Sponsor: Nanjing First Hospital, Nanjing Medical University

Brief Summary

The purpose of this study is to establish the optimal strategy for stenting in coronary bifurcation lesion.

Detailed Description

The current study is designed as a multicenter, randomized and prospective study aiming to compare the effect of two-stenting and simple stenting techniques in patients with complex bifurcation lesions. Based on the previous studies, the rate of 1-year target lesion failure events was around 14% after PCI with provisional stenting. And our previous data showed that this event at 12-month after two-stenting procedure was 7%. Considering the lost to follow-up, it is anticipated that up to 660 patients will be enrolled in the trial. All patients will have repeat angiography at 13 months, with clinical follow-up to 5 years.
