Brief Summary:
This study aims to compare vessel response and clinical outcomes of a biodegradable-polymer, ultra-thin strut, drug-eluting stent (Orsiro, Biotronik) and a durable-polymer, thin-strut, drug-eluting stent (Xience, Abbott) for the treatment of coronary bifurcation lesions with two-stent double-kissing crush technique. How the differences in stent platforms affect vessel healing process will be examined by optical coherence tomography.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Device: Orsiro stent Device: Xience stent Device: Any drug-eluting stent Not Applicable

Detailed Description:
Patients with true coronary bifurcation lesions (Medina [1, 1, 1] or [0, 1, 1]) will be enrolled and randomized to undergo two-stent double kissing crush technique with Orsiro or Xience. Pre-intervention and post-stenting optical coherence tomography will be performed during the index procedure. Another parallel prospective registry will enroll patients with bifurcation lesions treated with provisional one-stent strategy. All subjects will receive coronary angiography and optical coherence tomography follow-up at 3 and 12 months.
