It was reported that the patient presented with progressive angina on exertion.The procedure on (b)(6) 2016 was to treat a de novo lesion located in the proximal left anterior descending (lad) artery which was narrow and stenosed.Pre-dilatation was performed, with a 3.5x15mm balloon with residual stenosis less than 40% and a 3.0x18mm absorb gt1 was implanted at 16 atmospheres.Post-dilatation was performed with a 3.5x15mm non-abbott nc balloon, with residual stenosis less than 10%.However, no optical coherence tomography (oct) was performed to confirm whether the scaffold was fully apposed to the vessel wall.On (b)(6) 2017 the patient presented with chest pain experienced during biking.Oct was performed and the absorb gt1 scaffold was noted to have restenosis; however, the distal part of the scaffold had extra stenosis.The restenosis was treated with the implantation of a non-abbott stent (3.5x18) and post-dilatation with a 3.5x12 nc balloon at 20 atmospheres.The patient was reportedly taking the following medications: aspirin 100mg-qd, plavix 75mg-qd, amlodipin/olmesartan 5/20mg-qd, atorvastatin 40mg-qd and was confirmed to have had good compliance to their dual anti-platelet therapy.The patient will continued to be followed.No additional information was provided.
