Coronary chronic total occlusion （CTO）, defined as a ,total occlusion of duration 〉3 months, remains a technical challenge for the interventional cardiologists. The major limitation in percutaneous coronary intervention （PCI） of CTO is the inability to penetrate and cross the occlusion with a guidewire. It was reported that the immediate angiographic success rate varied from 50% to 70% using the standard antegrade techniques.1 To improve this suboptimal success rate, the authors firstly introduced retrograde approach through the collateral channels as a novel technique and successfully recanalized a left main CTO using this technique when demonstrating the live cases in Transcatheter Cardiovascular Therapeutics （TCT） 2005. Recently, modified techniques based on the retrograde approach have demonstrated that this approach could provide a high success rate with PCI.3-5 In the present report, we described a new method, wire trapping technique combined with retrograde approach, which was applied successfully in three patients with CTO.
