Resection of guide catheter fragments during coronary atherectomy in aorto-ostial lesions: a note of caution.

Angioplasty of coronary aorto-ostial lesions is considered to be troublesome with decreased acute and long-term results and high complication rates. We report a patient with an ostial right coronary artery lesion which was treated after failed PTCA with directional atherectomy as a rescue intervention. After a favorable angiographic and clinical outcome, plastic material was found in the AtheroCath's housing due to resection of the tip of the guide catheter.
