Percutaneous Intervention With GuideLiner Catheter in 4 Patients With Anomalous Coronary Artery Originating From Opposite Sinus of Valsalva.

Percutaneous intervention in anomalous coronary arteries originating from the opposite sinus of Valsalva is complicated by their unusual location and course, which makes selective cannulation difficult. The GuideLiner (Vascular Solutions, Inc.) is a monorail guide extension catheter designed to advance beyond the tip of a mother guide catheter to enable deep intubation of a coronary artery, provide extra support, and improve coaxial alignment. We describe the cases of 4 patients with an anomalous coronary artery originating from the opposite sinus of Valsalva-including 2 with acute myocardial infarction-who underwent successful percutaneous coronary intervention with use of a GuideLiner catheter.
