摘要
Coronary bifurcation lesions remain a challenging subset of lesions for percutaneous coronary intervention （PCI） with use of drug-eluting stents.Side branch （SB）is the most problematic lesion with higher rates of instent restenosis leading to the need for revascularization.1The current consensus based on clinical studies have reported that two-stent strategies are required in only a small number of patients.Of currently used complex stenting techniques,culotte stenting is comparable with the others.2-4 Unfortunately,the culotte technique has some limitations,of which double layers of metal struts is reported to be related to the occurrence of stent thrombosis （ST）.Stenting sequences of culotte stenting shares features with provisional T stenting,indicated by a jailed wire in a SB at risk of SB loss after stenting the main vessel （MV）.Accordingly we reported our modified mini-culotte stenting technique in 2008,5 but we found that mini-culotte is not always correctly used in China.As a result,it is crucial to systematically describe the tips and pitfalls of mini-culotte techniques in details.
