Initial experience with the Endicor X-sizer thrombectomy device in patients with ST segment elevation myocardial infarction.
We investigated 16 patients with ST segment elevation myocardial infarction who had an occluded coronary artery (TIMI 0) at initial angiogram. Instead of balloon angioplasty and stenting, patients were subjected to thrombectomy (Endicor X-sizer) and stenting. In 15/16 patients the occlusion could be crossed by the thrombectomy device resulting in TIMI flow 3 in all of them. Thereafter, stenting was performed. At final angiogram all 15 patients continued to show TIMI flow grade 3. Twelve-lead ECG was performed prior to and post-intervention. ST elevation was measured as the sum of eight leads for anterior infarction and of five leads for inferior infarction. In 13/15 patients, ECG analysis was possible (2 developed bundle branch block post-intervention). In all 13 patients, a > 50% ST decrease of the initial amount of ST elevation was observed reaching a > 70% reduction in 11 patients. Procedural complications were low (one coronary dissection after thrombectomy) and 30 days follow-up was uneventful. Thrombectomy using the Endicor X-Sizer device may become an attractive mechanical reperfusion strategy for patients with acute myocardial infarction.
