Retrograde Approach of CTO PCI
The success rate of the percutaneous coronary intervention for coronary chronic total occlusion (CTO-PCI) was 65–70% when using only the antegrade approach, so it was difficult to expect a high success rate. However, the introduction of the retrograde approach using the native collateral channel has significantly increased the success rate of the procedure. In the early days of the retrograde approach, the complexity and variability of the procedure and the possibility of complications caused practitioners to hesitate to use this method, but thanks to the development of techniques and tools, a recent report suggests that the retrograde approach is used for approximately 30% of all CTO-PCIs .
