Use of the Guideliner facilitated successful completion of PCI despite the use of a wide variety of guiding catheters in this series.Īngiography Coronary intervention Transradial. Proximal vessel angulation is significantly associated with the need for GuideLiner use during transradial intervention. TRIs requiring GuideLiner catheter support had significantly increased lesion complexity and vessel tortuosity. None of the Guideliner TRI cases required conversion to femoral access. A 45° proximal vessel angle predicted the need for GuideLiner use with a sensitivity of 73% and specificity of 74% (c-statistic 0.79). On multivariable analysis, proximal vessel angle independently predicted the need for GuideLiner support (AOR 1.4 per 10°, p<0.001). Lesion angle in the Guideliner group was also significantly greater (48°☓2° vs. In the presented cases, no complications occurred. The proximal vessel angle was significantly greater in the cases requiring GuideLiner support (74°☓5° vs. This novel technique offers 2 advantages: (1) delivery of stents through the GuideLiner with unsheathing, rather than risky pushing of equipment through severe tortuosities (2) improved guide length to approach distant targets, that is, via SVGs. Subjects who required use of the GuideLiner support catheter at the time of TRI were significantly older (69☑2years vs. The indications for TRI were similar between both groups. Multivariable analysis and receiver operator curves (ROC) were used to analyze predictors of GuideLiner use. The GuideLiner ® Coast Catheter adds a hydrophilic option to Teleflex’s market-leading guide extension portfolioanchored by the flagship GuideLiner ® V3 Catheterenabling physicians to select the level of deliverability and backup support needed for specific cases. SUPERIOR DELIVERABILITY 3 AND PUSHABILITY 4 Telescope GEC has superior deliverability 3 to assist in difficult cases. 1 Telescope GEC features bold technology and our market-leading 2 catheter expertise. Procedural and angiographic characteristics of all cases were analyzed. In difficult cases, guide extension catheters (GEC) provide extra backup support and improve access to distal lesions. 22 cases (15%) required use of the GuideLiner support catheter. This was a retrospective study reviewing 146 TRI cases performed at a single institution between August 2010 and June 2012. We hypothesized that TRI cases requiring GuideLiner support would have a greater proximal vessel angle and increased lesion angle tortuosity. The GuideLiner catheter (Vascular Solutions, Minneapolis,MN) is a guide catheter extension developed to provide increased guide catheter support. The GuideLiner (Vascular Solutions, Inc. Transradial coronary intervention (TRI) is increasingly common, but anatomic variations and lack of guide catheter support may increase the complexity of TRI. 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.
