A U-turn wiring technique for reverse-angled branches adjacent to ectasia: a case series

The UWT takes advantage of the ectasia as a space to U-turn the guidewire. The UWT does not require a hairpin-bend guidewire or a dual-lumen catheter. The guidewire can be easily pushed forward through a reversed SB. After successful wire insertion, the guidewire can be easily advanced deep into the side branch. The UWT facilitates wire crossing to a reverse-angled branch utilizing the coronary ectasia anatomy through a simple manipulation.
