Condition or disease | Intervention/treatment | Phase |
---|---|---|
Coronary Artery Disease | Device: Orsiro stent Device: Xience stent Device: Any drug-eluting stent | Not Applicable |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 150 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Patients with true coronary bifurcation lesions will be randomized to undergo two-stent DK-crush technique with Orsiro or Xience. Another parallel prospective registry will enroll patients with bifurcation lesions treated with provisional one-stent strategy. |
Masking: | None (Open Label) |
Primary Purpose: | Treatment |
Official Title: | A Randomized, Parallel, Active Controlled Study to Evaluate the Vascular Response of Orsiro vs. Xience Drug Eluting Stent System in Subjects With Coronary Bifurcation Lesions |
