A case of guide wire fracture with remnant filaments in the left anterior descending coronary artery and aorta.

Guide wire fractures during percutaneous coronary intervention (PCI) are very rare, but when they do occur they may lead to life-threatening complications, such as embolization, thrombus formation and perforation. In cases when percutaneous retrieval has failed, surgical extraction of the remnant fragments is recommended. We present a case of remnant guide wire filaments that remained in place without complications, over a one-year clinical follow up period.
