N2  - BACKGROUND: The presence of large thrombus burden  in patients presenting with acute myocardial infarction  (AMI) is common and associated with poor prognosis. This  study aimed to describe the feasibility and safety of the  novel 'mother-in-child' thrombectomy (MCT) technique in  patients presenting with AMI and large thrombus burden  undergoing percutaneous coronary intervention (PCI); CONCLUSION: This initial report suggests that  significant reduction in thrombus burden and improvement of  the coronary flow can be safely achieved in patients  presenting with AMI and large thrombus burden by using the  novel MCT technique. Copyright  2013 Elsevier Inc. All  rights reserved; METHODS: We studied 13 patients presenting with  AMI who underwent PCI with persistent large intracoronary  thrombus after standard thrombectomy. The procedure was  performed using a 5F 'Heartrail II-ST01' catheter (Terumo  Medical) into a 6F guiding system. Angiographic assessment  of thrombus burden and coronary flow was obtained at  baseline, immediately after thrombectomy and at the end of  the procedure; RESULTS: The mean age was 55.9+/-13.0 years and  involved mostly males (76.9%). All patients underwent PCI  via radial approach. Following MCT Thrombolysis In  Myocardial Infarction (TIMI) flow improved by 2 or more  degrees in 11 patients (84.5%), while visible angiographic  thrombus was reduced in 11 patients (84.5%). In the final  angiogram, normal TIMI flow was restored in 11 patients  (84.5%), with normal myocardial 'blush' in 7 patients  (53.8%) and total clearance of a visible thrombus in 7  patients (53.8%). Overall, 6 patients received thrombectomy  as 'stand-alone' procedure. All patients were discharged  alive after a mean of 5.6+/-2 days
