GuideLiner Catheter Use for Percutaneous Intervention Involving Anomalous Origin of a Single Coronary Trunk Arising from the Ascending Aorta.

Cases in which an anomalous single coronary trunk arises from the ascending aorta are extremely rare. In percutaneous coronary intervention for the lesion of a coronary artery anomaly, several problems may occur, including selection of a guide catheter, insufficient backup force, and difficulties of stent delivery. The GuideLiner catheter, which is a coaxial guide extension having the advantage of rapid exchange, facilitates coronary intervention for complex lesions. We report a case of angina having a lesion in the left anterior descending artery of a single coronary trunk arising from the ascending aorta. We successfully performed revascularization by using the GuideLiner catheter.
