Abstract
A 52-year-old male underwent percutaneous coronary intervention (PCI) using rotational atherectomy (RA: 1.5-mm burr) for a severely calcified lesion in the proximal to mid obtuse marginal (OM) branch. Even with 7 Fr extra back-up guiding catheter via femoral access, the burr could not cross the lesion due to insufficient back-up support. In order to achieve stronger back-up support, we kept the burr at the position in the OM branch and placed a supportive wire in left anterior descending artery through the side of drive-shaft sheath of the Rotablator, which sufficiently stabilized the guiding catheter during the ablation and the burr crossed the lesion. This case demonstrates that a simple technique of placing additional supportive wire in the other vessel during RA could be an effective and safe solution to facilitate improved back-up support without necessity to change the PCI system used already.
