(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.(b)(4).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.The bioresorbable vascular scaffold (bvs) system, absorb gt1, instructions for use (ifu) states: in small vessels (visually assess reference vessel diameter less than or equal to 2.75 mm), on-line qca or intravascular imaging with intravascular ultrasound or optical coherence tomography is strongly recommended to accurately measure and confirm appropriate vessel sizing (reference vessel diameter greater than or equal to 2.5 mm).The reported patient effects of angina and thrombosis, as listed in the ifu, are known adverse events associated with the use of a coronary scaffold in native coronary arteries.It is unknown if the ifu deviation contributed to the reported event.A conclusive cause for the reported patient effects and the relationship to the product, if any, cannot be determined and there is no indication of a product quality issue with respect to the design, manufacture or labeling of the device.The 3.0x28 mm absorb gt1 referenced, is filed under a separate medwatch report number.

It was reported that on (b)(6)2016, two absorb scaffolds, sizes 2.5x18 and 3.0x28, were implanted, using visual assessment, in the mid to distal left anterior descending coronary artery.On (b)(6)2017, the patient presented with chest pain and ekg changes.The two scaffolds were noted to be thrombosed at the site of overlap.A non-abbott stent was implanted as treatment and the condition resolved.There was no reported adverse patient sequela.No additional information was provided.
