Progress in the retrograde approach for chronic total coronary artery occlusion: a case with successful angioplasty using CART and reverse-anchoring techniques 3 years after failed PCI via a retrograde approach.

After the introduction of the retrograde approach in percutaneous coronary intervention for chronic total occlusion (CTO), different kinds of strategies and techniques have been developed in order to achieve final success. However, it has not been fully demonstrated whether these strategies and techniques can really improve the final result. We observed one case, for which the initial attempt of the retrograde approach for a CTO lesion was unsuccessful despite the successful approach of a retrograde guidewire to the lesion, and with the second retrograde approach 3 years later being eventually successful by using various kinds of strategies and techniques. This case clearly demonstrates how the final success through the retrograde approach can be achieved by using a combination of the improved strategies and techniques for CTO lesions. 2008 Wiley-Liss, Inc.
