Event Description

The manufacturer was notified of the following event via the sure-avr patient registry: a solo smart size 23 was implanted on (b)(6) 2016.At the time of operation, a mean gradient of 11 mmhg and paravalvular leak 1+ were reported.The patient experienced thrombocytopenia on (b)(6) 2016.The valve was functioning well at follow up in (b)(6) 2017, with a mean gradient of 12 mmhg and no central or paravalvular leak.The total cross-clamp time was 59 minutes, and the total pump time was 72 minutes.The event was reported by the site as "valve related".

Manufacturer Narrative

The manufacturing and material records for the solo smart heart valve, model #icv1248 , s/n # (b)(4), as they pertain to the reported event, were retrieved and reviewed by quality engineering at livanova canada corp.The results confirmed that this valve satisfied all material, visual, and performance standards required for a (model #icv1248) solo smart heart valve at the time of manufacture and release.Based on the document review performed, no manufacturing deficiencies were identified.Given that the patient's thrombocytopenia resolved without transfusion, and the device remained implanted and was functioning well one year post-operatively, the event is unlikely to be related to the functionality of the device.Furthermore, thrombocytopenia is a known complication associated with cardiopulmonary bypass.It is therefore possible that the event is related to the procedure and not to the device.However, as no device investigation can be performed, the root cause of the event cannot be determined.
