Promus element plus clinical study.It was reported that myocardial infarction and in-stent restenosis (isr) occurred.In (b)(6) 2012, patient presented due unstable angina and myocardial infarction.Subsequently, the index procedure was performed.The target lesion was a de novo and culprit lesion for st-elevation myocardial infarction (stemi) located in the 1st obtuse marginal (om1) with 99% stenosis and was 32mm long with a reference vessel diameter of 2.75mm.The lesion was treated with pre-dilatation and placement of 2.75x38mm promus element plus stent with 0% residual stenosis.On the following day, the patient was discharged on aspirin and clopidogrel.In (b)(6) 2017, the patient presented to emergency department with the complaints of cardiac arrest associated with chest pain.The patient received one shock from automated external defibrillator for cardiac arrest.The emergency medical services noted the patient had no pulses and was turning cyanotic, and performed cardiopulmonary resuscitation after which he had spontaneous return of circulation.Troponin level was found to be elevated and the site reported an event of myocardial infarction.The patient was further referred for cardiac catheterization which revealed moderate isr of the study stent noted in the proximal of om1 and 40 to 50% narrowing was noted.On the same day, the 90% isr and jailing of stent located at om1 was treated with kissing balloon angioplasty with 20% residual restenosis.The event cardiac arrest was considered resolved on the same day.Two days after, the event non-st segment elevation myocardial infarction was considered to be resolved and the patient was discharged from the hospital.
