Novel Use of the GuideLiner Catheter to Deliver Rotational Atherectomy Burrs in Tortuous Vessels.

Vo M, Minhas K, Kass M, Ravandi A - Case Rep Cardiol (2014)

Bottom Line: In tortuous vessels it is often difficult to advance the burr without rotation and possible injury to the endothelium of healthy vessel.The GuideLiner catheter, a child in mother catheter, has recently been used to allow for increased support for delivery of stents through tortuous vessels.We report a novel use of the GuideLiner for the delivery of an RA burr in tortuous vessels requiring increased guide support.

ABSTRACT
Rotational atherectomy (RA) for heavily calcified lesions is essential for improved stent delivery and stent expansion. In tortuous vessels it is often difficult to advance the burr without rotation and possible injury to the endothelium of healthy vessel. The GuideLiner catheter, a child in mother catheter, has recently been used to allow for increased support for delivery of stents through tortuous vessels. We report a novel use of the GuideLiner for the delivery of an RA burr in tortuous vessels requiring increased guide support.
