(b)(6) study.It was reported that the patient died.In (b)(6) 2015, clinical assessment indicated that the patient's qualifying condition was stable angina.The target lesion, a de novo lesion, was located in the proximal right coronary artery (rca) with 90% stenosis and was 22mm long with a reference vessel diameter of 3.5mm.There was mild vessel tortuosity.The target lesion was treated with pre-dilatation and a 3.50x24mm promus premier everolimus-eluting platinum chromium coronary stent.Post-dilatation was performed with 0% residual stenosis.Four days later, the patient was discharged on aspirin and clopidogrel.In (b)(6) 2016, the patient was awoken by substernal chest pain, which felt different than pain previously experienced.The patient did not use sublingual nitroglycerin at home, and called emergency medical services (ems).The patient's symptoms resolved after being placed on oxygen.The patient was hospitalized with complaints of shortness of breath and dizziness for an hour, abdominal pain, and right jaw pain.The patient denied exertional chest pain.The patent reported being compliant with dialysis treatments, anticoagulation and with all medications, although patient had not been able to complete his dialysis the day prior due to the abdominal pain.On admission, troponin levels were elevated, likely due to the patient's existing conditions of end stage renal disease (esrd) and congestive heart failure.Nt-probnp levels were also elevated.Treatment with antibiotics was planned.The patient received dopamine gtt.On the following day, cardiology was consulted due to the patient's elevated heart rate.The patient's heart rate increased to the 160s at times and then returned to normal sinus rhythm.Before the patient could be transferred to the intensive care unit (icu), the patient's mental status decreased and patient's heart rate went to a brady rhythm with couplets.The patient went into ventricular tachycardia rhythm followed by ventricular fibrillation with no pulse.Code blue was called and advanced cardiac life support (acls) protocol was initiated for 20 minutes without a return of spontaneous circulation.On the same day, the patient died due to an unknown cause of death.

It was further reported that post index procedure, the patient was left with significant residual left main coronary and left circumflex artery lesions and received protected percutaneous coronary intervention (pci) with a non-bsc percutaneous ventricular assist device support with deployment of five stents in (b)(6) 2015.In (b)(6) 2016, the patient's systolic blood pressure was in the 80's and 90's.The patient was thought to be in the early stages of cardiogenic shock and it was felt best to manage medically given the patient's severe co-morbid conditions.The patient received dopamine.The following day, the patient developed worsening hypotension before going into ventricular tachycardia followed by ventricular fibrillation with no pulse.Although no ischemic changes were noted on the electrocardiogram (ecg), stent thrombosis was reported to be a possibility.Stent thrombosis could not be confirmed nor ruled out and a clear cause of death could not be confirmed because an autopsy was not performed.
