(b)(6)clinical study.Same case as mfr report#: 2134265-2017-00215, 2134265-2017-00216, 2134265-2017-00217 it was reported that following a coronary artery drug eluting stenting treatment procedure, myocardial infarction (mi), stent thrombosis (st), and incomplete stent apposition occurred.In (b)(6) 2012, the patient presented due to myocardial infarction and unstable angina (braunwald¿s classification) and was referred for cardiac catheterization.The de novo target lesion was located in the distal right coronary artery (dist rca) with 90% stenosis and was 22 mm long with a reference vessel diameter of 3.00 mm.The target lesion was treated with pre-dilation and placement of a 3.00 x 20 mm promus element plus stent and a 3.00 x 8 mm promus element plus stent in overlapping fashion, with 0% residual stenosis following post-dilation.The patient was discharged on aspirin and clopidogrel the next day.In (b)(6) 2016, the patient presented with chest pain associated with diaphoresis and mild shortness of breath.Subsequently the patient was referred for cardiac catheterization.A 100% stent thrombosis at dist rca was noted and a samurai guidewire was placed in the vessel which resulted in distal embolization of the thrombus to the posterolateral branch.The under expansion of previously placed study stents in dist rca was then treated with balloon angioplasty and placement of a 3.5 x 16 mm synergy ii drug-eluting stent in an overlapping fashion with previously placed study stent.Following post-dilation the overlapping segment with the previously placed study stent still appeared to be under expanded.This was treated with further balloon dilation using a 4 x 15 mm quantum maverick balloon.The event was considered as resolved and the patient was discharged on dual antiplatelet therapy the next day.
