The “GuideLiner Balloon Assisted Tracking” (GBAT) is relatively easy to perform and has a low risk of complications. We describe a novel technique that would facilitate delivery of the GuideLiner catheter across difficult segments and increase procedural success rates. This sometimes can be difficult through tortuous and calcified vessels or through previously stented segments. To increase success rates, the GuideLiner should be delivered as close as possible to, and sometimes across, the target coronary lesion. Stent delivery failure occurs in up to 5% of all PCI cases, which can result in suboptimal revascularization and has been associated with increased complication rates The GuideLiner catheter, a mother-and-child catheter that can be delivered deep into the coronary artery, provides excellent support and facilitates stent delivery. Despite improvements in-stent profile, stent delivery can still be problematic in complex coronary anatomy. Introduction With the advent of drug-eluting stents, an increasing number of difficult lesions are treated by percutaneous intervention (PCI). This technique is termed GuideLiner Balloon Assisted Tracking (GBAT).ġ. This technique can be applied to 5.5 Fr., 6 Fr., and 7 Fr. In cases which the GuideLiner catheter cannot be advanced even with balloon anchoring technique, we inflate a noncompliant balloon protruding from the GuideLiner catheter at nominal pressure and both the GuideLiner and the balloon are advanced over the coronary guidewire through the tortuous segments. The use of guide extension catheters, such as GuideLiner, allows for increased guide support and facilitates device delivery in tortuous vessels.
