Brief Summary
Prospective, controlled, double randomized, non-blinded, multicenter, investigator initiated, academic superiority trial comparing optical coherence tomography (OCT) guided vs. angiography guided wire recrossing in jailed side branches (SB) (1. randomization 1:1)(superiority) and comparing Medtronic Resolute Integrity and Xience Prime for stent strut apposition in the SB ostium (2. randomization 1:1) (superiority). Acute primary endpoint and 30 days clinical follow-up. Hypothesis: OCT guided wire recrossing in bifurcation stenting results in less malapposed struts in the segment facing the SB ostium. Secondary hypothesis: Treatment by Medtronic Resolute Integrity stent results in less malapposed struts at the bifurcation segment compared to treatment by the Abbott Xience Prime stent.
