Same case as mdr id #: 2134265-2016-00019; 2134265-2015-09377; 2134265-2016-00294; 2134265-2016-00293.(b)(4).It was reported that myocardial infarction (mi) and in-stent restenosis (isr) occurred.In (b)(6) 2013, the patient was presented with unstable angina and was referred for cardiac catheterization.Subsequently, index procedure were performed.The first target lesion was located in the mid right coronary artery (rca)with 75% stenosis and was 30 mm long with a reference vessel diameter of 3.0 mm.The lesion was treated with direct stent placement using a 3.00mmx38mm promus element plus drug-eluting stent.However, a dissection occurred which was then treated with placement of a 3.00mmx16mm promus element plus drug-eluting stent which overlapped proximally, resulting to 0% residual stenosis.The second target lesion was located in the distal left anterior descending (lad) artery with 75% stenosis and was 15 mm long with a reference vessel diameter of 2.5 mm.The lesion was treated with direct stent placement using a 2.50mmx20mm promus element plus drug-eluting stent.Following post-dilatation resulting to 0% residual stenosis.One day post procedure, the patient was discharged on aspirin and prasugrel.In (b)(6) 2015, the patient experienced unstable angina and target lesion revascularization was performed in the distal lad with promus element 2.5x8mm and a non-bsc stent in (b)(6) 2015, the patient presented with left sided chest pain and was hospitalized on the same day.The patient was then referred for cardiac catheterization.Elevated troponin values were observed and site reported an event of mi.Subsequently, coronary angiography revealed 50% stenosis in the mid lad, 90% in-stent restenosis (isr) of distal study stents and 50% ostial stenosis in second diagonal branch.Three days post-hospitalization, a 182cm choice floppy guidewire was directed down the mid lad by ballooning with a 2.50x20mm maverick balloon catheter and a 2.25x15mm cutting balloon catheter with some diffused spasm of the vessel noted post-treatment which was relieved with an intracoronary nitroglycerin.Subsequently, a 2.5x20mm promus premier drug-eluting was placed and balloon angioplasty was performed in mid lad resulting from 99% to 0% restenosis.Six days later, the patient complained of repeat chest discomfort and was brought back to cath lab.Coronary angiography revealed mild to moderate narrowing from intimal hyperplasia in the distal third of the stent segment.Isr in the distal lad was treated with cutting balloon angioplasty.On the following day, the event was considered resolved and the patient was discharged on aspirin and prasugrel.
