Event Description

It was reported that on (b)(6) 2021 a patient underwent an explant of their 27 mm, sjm masters series mechanical heart valve on (b)(6) , 2021.The reason for the explant is unknown and the device (s/n (b)(4)) has been discarded and will not be returned for analysis.Three months later, on (b)(6) 2021, the patient required another re-do mitral valve replacement (mvr) and the second 27 mm, sjm masters series mechanical heart valve (s/n (b)(4)) was explanted.The need for explant three months post implant remains unknown, however.The patients pre-explant international normalized ratio (inr) was 3.4 units.Thrombus was found inside the leaflet hinge which appeared to be impeding the leaflets ability to open and close, causing the leaflets to stick.The patients condition may have also played a role.The second sjm masters series mechanical heart valve, (s/n (b)(4)) will be returning for analysis.A full multifaceted investigation has been requested from the implanting physician.No further information has been provided.Related manufacturer reference #3007113487-2021-00010.

Event Description

It was reported that on (b)(6) 2018 a 27mm sjm masters series mechanical heart valve (s/n (b)(6)) was implanted.On (b)(6) 2021 the patient underwent an explant of the 27 mm, sjm masters series mechanical heart valve.The reason for the explant is unknown.Upon explant of the valve, pannus had been observed.A replacement 27mm sjm masters series mechanical heart valve (s/n (b)(6)) was implanted.Three months later, on (b)(6) 2021, the patient required re-do mitral valve replacement (mvr) and the 27 mm, sjm masters series mechanical heart valve (s/n (b)(6)) was explanted.The need for explant three months post implant remains unknown.The patients pre-explant international normalized ratio (inr) was 3.4 units.Thrombus was found inside the leaflet hinge which appeared to be impeding the leaflets ability to open and close, causing the leaflets to stick.The patient's condition may have also played a role, however, the physician confirms the patient did not have a history of coagulation issues such as protein deficiencies, cancer or smoking etc.An epic stented porcine heart valve was implanted during the procedure and was noted to have been functioning properly.Subsequent to the initially filed information, the following information was received on 15 july, 2021.Two weeks post re-do mvr, the patient's condition had not improved.It was reported the patients flows were 1.9l and the patient's ejection fraction (ef) to be 20%.The patient was diagnosed with pneumonia.31 days post operatively, the patient was reported to have passed away on (b)(6) 2021.In the physicians opinion, the patient's death was related to the cardiac arrest during the procedure on (b)(6) 2021 and the patients inability to improve post implant.The need for a re-do mvr three months after the last operation is also reported as a contributing cause to the patient's death.No additional information provided.Related manufacturer reference #3007113487-2021-00010.

Manufacturer Narrative

Explant was reported due to thrombus and malfunction of leaflets.The investigation found that the mechanical leaflets were immobilized in the closed position.There was organizing thrombus with focal calcifications at both pivot recesses.There was incomplete closure of mechanical leaflets.No inflammation was present.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed and the product met all specifications.The immobilizing thrombus would have contributed to the leaflets malfunction.
