In recent years, the use of a retrograde approach has become a common practice in the treatment of chronic total occlusion (CTO) of the coronary ostium and artery with an anomalous origin. Use of this approach has increased the chances of a successful percutaneous coronary intervention (PCI). However, the approach requires capturing the retrograde guidewire within the aorta, which can often pose a problem. Therefore, we developed a technique in which the retrograde guidewire is passed through the CTO and inserted directly into the antegrade guiding catheter in the ascending aorta. This technique enabled the successful treatment of the ostial CTO of the right coronary artery using retrograde PCI.
