title: Reverse bent wiring with Crusade catheter can be a useful technique for penetrating an abrupt-type entry of coronary occlusion at branching ostium.
abstract: We encountered a case of chronic total in-stent occlusion which involving an abrupt-type entry at an obtuse marginal branching ostium. It is usually difficult to antegradely penetrate this kind of proximal fibrous cap. Therefore, we adopted a reverse bent wiring technique with a Crusade catheter and successfully completed all procedures. This technique is very simple but can be very effective in specific situations in daily percutaneous coronary intervention (PCI). Many PCI operators may empirically adopt this kind of wire manipulation technique. However, this kind of technique has never been officially reported to our knowledge.
