Background: Failure of guidewire passage is the most common cause of procedural failure in chronic total occlusion(CTO). We have developed this novel supporting double lumen catheter(Multidirectional double lumen catheter(Ashai Intec Co. Ltd, Aichi, Japan) with arrow shaped tip allows for manipulation of two guidewires with the torquability and two wide bevels on the opposite side of catheter. It is designed to guide the second wire direction and angle into the true lumen, if the first wire goes into false lumen. Methods: We used this catheter in consecutive 12 patients(10 male, 57짹8 years) with CTO and investigated procedural outcomes. Two diabetic patients were enrolled. Target lesion localized in LAD 58%, RCA 34% and LCx 8%. Mean lesion length was 32.5짹 15.3mm. Results: Initial technically success rate(TIMI 3 distal flow) was 91.6%.(11/12) In one patient, wire was not re-entered into the true lumen during subintimal coronary intervention. There was no peri-procedural complication including coronary perforation, acute myocardial infarction or subacute thrombosis after the procedure. Conclusion: Our preliminary result shows the multidirectional double lumen catheter may be a useful device for the treatment of CTO.
