A bidirectional approach for percutaneous coronary intervention for chronic total occlusion (CTO-PCI) using ipsilateral collaterals with a single guiding catheter limits procedural choices. The CTO of the left circumflex artery with ipsilateral collateral artery was treated by the bidirectional approach using a single guiding catheter. While the retrograde wire directly crossed the CTO lesion, the microcatheter could not pass the CTO lesion despite the conventional strategies. Therefore, we performed the wire rendezvous and chasing wire techniques. The wire rendezvous technique enables deeper retrograde guidewire progression, and the antegrade microcatheter can reach the CTO entry. The chasing wire technique enables the antegrade guidewire to pass the route made by the retrograde guidewire. These techniques might offer a possible solution for bidirectional CTO-PCI using a single guiding catheter. However, this technique should be considered as a last resort because of the risk of rapid reocclusion.

AbstractPercutaneous coronary intervention (PCI) for high takeoff left main is challenging, as it poses difficulties with the engagement of the guiding catheter and establishment of backup support. This report examines the case of a 53-year-old woman with history of anterior wall myocardial infarction with a ventricular septal defect (VSD), who was treated with left anterior descending (LAD) angioplasty and VSD device closure done 4 years back, and now she presented with unstable angina. After successful engagement of 5F Tiger diagnostic catheter through a right radial artery, the angiography revealed an 80% stenosis of the proximal LAD and in-stent restenosis 70% of mid-LAD. The authors tried to engage the left coronary system through the right femoral artery with 6F Judkins left, 6F Amplatzer left, 6F EBU, and 6F XBU. They could not cannulate because of high takeoff left main, so they switched to right radial access. Then they engaged a 6F 3.5 EBU catheter. Due to the weak backup support of the guiding catheter, they used another wire to stabilize it and the stent was implanted successfully. This is one of the rare case reports of PCI for high takeoff left main.

AbstractPercutaneous coronary intervention (PCI) for anomalous right coronary artery (RCA), originating from the left coronary cusp is challenging, because of the difficulty in engaging the guiding catheter coaxially, and delivering balloons and stents. A 65-year-old man with effort angina underwent PCI for anomalous RCA. This report describes the method we used. Although, delivering the balloon was difficult in short of the guiding catheter's backup force, we finally succeeded by using one more guiding catheter and the balloon-anchored CoKatte®, a novel, straight 4.5-French child catheter, to strengthen the backup force.

Percutaneous coronary intervention (PCI) for anomalous left coronary artery (LCA) originating from the noncoronary cusp (NCC) is challenging, as it poses difficulties with the engagement of the guiding catheter and the establishment of backup support. This report examines the case of a 69-year-old woman with unstable angina of anomalous LCA origin. The computed tomography showed a diffuse plaque in the middle of the left anterior descending (LAD) artery and an anomalous LCA originating from the NCC. After successful engagement of a straightened Judkins-Left diagnostic catheter, the angiography revealed a diffuse plaque in the middle of the LAD artery. We then engaged a Judkins-Right guiding catheter. Due to the weak backup support of the guiding catheter, we used another wire to stabilize it, and the stent was then implanted successfully. To our knowledge, this is the first case report of PCI for an anomalous LCA originating from the NCC.
