title: Use of the X-SIXER catheter system in the treatment of acute thrombotic coronary occlusion.
abstract: The X-SIZER  thromboatherectomy catheter system (EndiCOR Medical, Inc.) was initially developed for the treatment of thrombus in acute coronary syndromes. We present the case of a 64-year-old man with thrombotic occlusion of the left circumflex coronary artery. Antegrade flow was restored by aspiration of platelet thrombus at the point of occlusion, although the catheter was unable to cross the underlying stenosis. Its limited ability to cross severe stenoses or reduce lesion severity suggests that the X-SIZER should not be regarded as an atherectomy device. However, this case report suggests that the X-SIZER device has potential as an adjunct to PTCA and stenting in reducing the risk associated with thrombotic occlusion.
