    A 73-year-old woman with acute inferior ST-elevation myocardial infarction underwent primary PCI via right radial access.

  • 2

    The case involved extreme upper-limb arterial tortuosity with a near-complete circular brachial artery loop.

  • 3

    Successful guidewire traversal did not achieve functional access due to failure of geometric correction.

  • 4

    A structured escalation strategy using progressively higher-support guidewires restored functional access.

  • 5

    The case emphasizes the need to distinguish between traversal success and effective catheter performance in PCI.
