title: Modified mother-child technique using a buddy wire.
abstract: For percutaneous coronary intervention, 6 Fr guiding catheters are the current standard. However, when treating complex coronary lesions, stent delivery is sometimes difficult with a 6 Fr system because of limited back-up support. Several strategies have been proposed in order to overcome this disadvantage, including active/passive guiding- catheter support, wire support, and the anchor-balloon technique. The 4-in-6 mother-child technique is one of the most effective techniques to deliver stents into complex lesions. In the present study, we introduced a new technique in which a second guidewire was used as a buddy wire in combination with the 4 Fr mother-child technique in a case in which stent delivery via the standard 4-in-6 technique failed.
