GuideLiner Balloon Assisted Tracking for deep cathether intubation to address challenging distal coronary lesions.

As the medical treatment and survivability of coronary artery disease improve, patients requiring catheter-based coronary intervention present with increasingly challenging coronary anatomy. Navigating complicated coronary anatomy requires a diverse armamentarium of techniques to reach distal target lesions. Here, we discuss a case in which we used GuideLiner Balloon Assisted Tracking, a technique formerly used to achieve difficult radial access, to facilitate delivery of a drug-eluting stent to a challenging coronary target.
