`presentation
`A 58 year old gentleman with hypertension presented to our
`emergency room with inferior STEMI. He was taken emergently
`to the cardiac catheterization laboratory for coronary
`angiography and primary PCI.
`initiaL FinDinGs
`Coronary angiography showed a tortuous right coronary artery
`(RCA) with an occlusive thrombus in the mid to distal coronary
`segment (Figure 1). The left coronary system was unremarkable.
`treatment
`The ostium of the RCA was engaged using a 6F ART 3.5 guide
`catheter. A BMW guidewire would not advance past the
`proximal RCA segment. A polymer covered ChoICE® PT floppy
`guidewire with balloon support crossed the thrombotic
`lesion into the distal RCA (Figure 2). A 3 x 15mm Trek balloon
`was passed with difficulty into the lesion and angioplasty
`performed. Attempts to pass a 4 x 23mm Xience V® drug eluting
`stent were unsuccessful and the stent would not pass through
`the proximal RCA.
`A 6F GuideLiner was then used, the tip of which was positioned
`in the distal RCA using the 3mm Trek as an anchoring balloon
`(Figures 3 & 4). The 4 x 23mm Xience V stent was then delivered
`to the lesion site, the GuideLiner catheter withdrawn, and the
`stent deployed (Figure 5). An excellent angiographic result was
`obtained (Figure 6).

`concLUsion
`The GuideLiner catheter is a new tool which facilitates complex
`primary PCI in STEMI patients. It saves critical time in this patient
`subset. It makes the difference between success and failure and
`converts an impossible case to a possible one.
`sUmmary
`The GuideLiner catheter allowed the delivery of a large drug
`eluting stent through a very tortuous artery to the lesion
`site. Importantly, the pressure from the tip of the GuideLiner
`catheter showed that flow was maintained normally with no
`ventriculization or damping, and angiographically it was noted
`that the GuideLiner conformed to the vessel tortuosity and did
`not kink the vessel, which would have occurred if stiff wires were
`used to facilitate delivery of the stent.

`GuideLiner catheters are intended to be used in conjunction with guide catheters to access discrete regions of the coronary and/or peripheral
`vasculature, and to facilitate placement and exchange of guidewires and other interventional devices.
