Coronary bifurcation stenting. Current techniques, outcome and possible future developments

Percutaneous treatment of coronary bifurcation lesions remained challenging in the stent era, with restenosis rates greater than 30% and no advantage from the routine use of kissing stents. Drug eluting stents (DES) have dramatically reduced the restenosis rates (RR) in the main vessel, but with conventional T-stenting double digits figures are still reported for the side-branch because of poor ostial coverage. The techniques of kissing stenting able to provide full lesion coverage (Culotte, V-stenting, Crush) have the potential to improve these results but the development of dedicated DES is probably needed to obtain consistently high procedural and long-term success.
