Manufacturer Narrative

A complete manufacturing and material records review for the device has been performed.The results confirmed that the device satisfied all material, visual and performance standards required at the time of manufacture and release.Since the device was discarded at the hospital due to blood contamination and was not returned to the manufacturer, no further investigation on the device is possible.Based on the manufacturer's experience, events of intra-operative leaflet dysfunction could occur due to interference of the patient's native mitral valve, when this is not fully removed, since the device was not returned to the manufacturer for further investigation, definite root cause of the reported event cannot be established.However, a review of the manufacturing and material records confirmed that the device satisfied all material, visual and performance standards required at the time of manufacture and release.Should further information be received in the future, the manufacturer will provide a follow up report.

Event Description

The manufacturer was informed of the dysfunction that noticed with the leaflets of the optiform valve.As reported, the mitral valve and calcified tissue were trimmed.After the implantation of the optiform valve size 29, it was noticed that the leaflets were stuck.The valve was removed.After the explant, the leaflets still were not moving and during checking the valve one of the leaflets broke and fell off.Another optiform valve (same model) was implanted in the patient as a replacement.As reported, the operation was successfully completed, the patient was not affected.

Event Description

On (b)(6) 2022, the following mitral valve replacement with optiform valve size 29 was performed.In this mvr, the mitral valve leaflets were removed, the tendinous cord of the anterior valve was fixed to the ascending of the posterior valve ring and all the subvalvular structures of the mitral valve were preserved.As reported, first, the anterior flap connecting the anterior and posterior papillary tendon into two sheets were trimmed (about 10mm × 50mm size).Then, the two pieces of flaky tissue were turned back and placed behind the posterior valve at the near anterior and posterior junction, and fix them behind the posterior leaflet with intermittent horizontal mattress suture with a gasket.Afterward, the f7-029 valve was implanted and the valve leaflets were opened in the fore-and-aft direction.After the implantation of the optiform valve size 29, it was noticed that the leaflets were stuck.The valve was removed.After the explant, the leaflets were still not moving and during checking the valve one of the leaflets broke and fell off.Another optiform valve (same model) was implanted in the patient as a replacement.As reported, the operation was successfully completed, and patient was not affected.

Manufacturer Narrative

Based on the manufacturer's experience, events of intra-operative leaflet dysfunction could occur due to interference of the patient's native mitral valve, when this is not fully removed ( as reported, the sub-valvular structures were preserved).Since the device was not returned to the manufacturer for further investigation, a definitive root cause of the reported event cannot be established.However, a review of the manufacturing and material records confirmed that the device satisfied all material, visual and performance standards required at the time of manufacture and release.Should further information be received in the future, the manufacturer will provide a follow up report.
