Figure 18: Case Demonstrating Side-branch Technique
You can see from this RAO view (b) that a relatively large right ventricular branch forks at quite a wide angle. This large side-branch is not suitable for the side-branch technique but the smaller right ventricular branch leading from the same portion is suitable (c). A large dissection can be seen in the occluded portion, but dilating with a 1.5mm balloon and consequent recanalization allows the wire to pass along to the distal true lumen.
