Same case as mdr id: 2134265-2018-03410.It was reported that chest pain and acute thrombosis occurred.In (b)(6) 2018, the patient presented with st-elevation myocardial infarction.Vascular access was obtained via the right femoral artery utilizing retrograde approach.The 100% stenosed, 12 mm in length target lesion was located in the proximal left anterior descending (lad) artery.A 6fr sheath was inserted and a guide wire was advanced and crossed the lesion.Following predilitation with a non-bsc balloon, a 3.00x28mm synergy ii drug-eluting stent was deployed at 12 atmopsheres (atm) for 16 seconds.A 3.25x15mm nc emerge balloon catheter was advanced for further dilatation at 12 atm for 17 seconds.Following dilatation, the devices were removed and hemostasis was successfully obtained.Post procedure, the patient was given effient and was resting comfortably with no acute distress noted.Following completion of the percutaneous coronary intervention (pci), the patient was transferred to the intensive care unit (icu) where they complained of chest pain.Repeat electrocardiogram (ecg) was performed which showed the exact same pattern as prior to the pci and a repeat angiogram confirmed acute stent thrombosis at the proximal segment of the stent.A 3.5mm x 15 mm nc emerge balloon catheter was advanced and inflated the entire stent at 10 atm for 11 seconds, 12 atm for 6 seconds, 12 atm for 8 seconds, and 12 atm for 12 seconds.The stent appeared to have a good apposition and the vessel re-opened with timi-3 flow but there was haziness at the proximal stent segment.The physician deployed a 3.5x18mm non-bsc stent at 14 atm for 14 seconds to cover the proximal segment of the synergy stent.The initial 100% stenosis was reduced resulting in 0% residual with normal timi-3 flow.No further patient complications were reported and the patient's status was good.The patient was kept on aggrastat infusion for 18 hours and was discharged on dual-antiplatelet with aspirin and effient.The patient was enrolled in cardiac rehab upon discharge.
