Successful transradial coronary angioplasty and stenting using a self-expandable RADIUS stent to the anomalous left main coronary artery.

Stenting of anomalous coronary artery is technically challenging both from the femoral and radial approaches because of difficulty in cannulating the artery by the guiding catheters with enough back-up support for delivering the stent. We report the first case in the literature of transradial coronary angioplasty and stenting to an anomalous left main coronary artery originating from the right sinus of Valsalva. Left Amplatz guidance from the radial approach provided an adequate platform to advance the stent using a dummy guidewire technique, and a self-expandable RADIUS stent was successfully deployed in a tortuous lesion of the anomalous artery.
