Patient id: (b)(6).It was reported that a percutaneous coronary intervention was performed on (b)(6) 2019.A 2.75x18mm xience alpine stent was implanted in the proximal-mid left anterior descending (lad) coronary artery lesion and a 2.5x12mm xience alpine stent was implanted in the mid lad.The procedure was performed without complications.Starting on (b)(6) 2019, the patient experienced acute on chronic heart failure.The patient was admitted to the hospital with dyspnea, orthopnea, and angina.Elevated troponin and the ejection fraction was observed at 50-55%.Reportedly, the elevated troponin was related to demand ischemia secondary to heart failure and atrial fibrillation.Medications were provided.On (b)(6) 2019, a non-abbott stent was implanted in the stenosed proximal lad, more proximal and slightly overlapping the previously implanted mid-proximal lad 2.75x18mm xience alpine stent.Medications were also provided.Per physician, the events were unrelated to the xience alpine stents and unrelated to the index procedure.There was no device malfunction.The event resolved without sequela.There was no additional information provided regarding this issue.

The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.It should be noted that the reported patient effect(s) of angina, ischemia and atrial fibrillation are listed in the xience alpine everolimus eluting coronary stent systems instructions for use as a known patient effect(s) of coronary stenting procedures.A conclusive cause for the reported patient effect(s), and the relationship to the product, if any, cannot be determined.There is no indication of a product quality issue with respect to manufacture, design or labeling.
