Percutaneous coronary intervention (PCI) of mammary artery bypass grafts through a trans‐radial (TR) approach can present unique challenges, including coaxial vessel engagement of the guiding catheter, adequate visualization of the target lesion, sufficient backup support for equipment delivery, and the ability to reach very distal lesions. The GuideLiner catheter, a rapid exchange monorail mother‐in‐daughter system, facilitates successful interventions in such challenging anatomy. We present a case of a patient undergoing PCI of a right internal mammary artery (RIMA) graft via TR access in whom the graft could not be engaged with any guiding catheter. Using a balloon tracking technique over a guidewire, a GuideLiner was placed as an extension of the guiding catheter and facilitated TR‐PCI by overcoming technical challenges associated with difficult anatomy.
