Percutaneous coronary intervention of heavily calcified coronary vessels can be challenging due to difficult equipment delivery and suboptimal stent expansion, leading to worse clinical outcomes. Supportive guidewires are designed to facilitate equipment delivery. We present two cases of heavily calcified and tortuous coronary lesions in which use of support guidewires hindered balloon and stent delivery, possibly by increasing friction between equipment and the wall of the coronary vessel. Equipment delivery was achieved using less supportive workhorse guidewires.
