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

Abstract

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.

“…Although the device reduces the lumen of the guide by 1 Fr size, it can be rapidly exchanged and deployed through a hemostatic valve . Additional merits of the device include improved coaxial alignment when the guiding catheter has poor coaxial engagement, increased support to facilitate device delivery, and reducing contrast volume by selective injection . The ability to provide increased support is especially useful in vessels that are tortuous, calcified, or both with limited deliverability of PCI equipment.…”
