As reported in a research article, endocarditis, stenosis, and thickening of the valve leaflets was noted 5 years after the valve was implanted.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed and the product met all specifications.A more comprehensive assessment, including pathological examination of the valve tissue, could not be performed as the event was non-contemporaneously reported through a literature review and no device was received for analysis.The reported leaflet thickening could have contributed to the stenosis reported, however the cause of the leaflet thickening could not be conclusively determined.There is no indication of a product quality issue with regards to manufacture, design, or labeling.

The abstract article, "trifecta bioprostheses: evaluation of the safety based on the study of degenerations according to the varc-3 classification", was reviewed.The research article is a retrospective single center experience to evaluate the intrinsic imputability of trifecta for dysfunction according to the varc-3 classification in patients implanted and to reassess their referencing in our center.Trifecta valve was the device associated with this study.The article concluded, the classification of failures according to varc-3 indicated the intrinsic imputability of the trifecta¿ bioprostheses regarding to the number of svd-type dysfunctions.Although this study has limitations, it shows the understatement of medical-devices-vigilance cases by the medical staff.[the primary author of this article is richez, ophelie, amiens-picardie university hospital, 1 rond-point du professeur christian cabrol, 80054 amiens, france, with email address of : richez.Ophelie@chu-amiens.Fr].It was reported that on (b)(6) 2015, a 23mm trifecta valve was successfully implanted in a patient with calcified aortic stenosis.In (b)(6) 2020, it was reported that there was endocarditis on bioprosthesis.The patient was on amoxicillin 2 g x 4 per day and associated with rifampicin600 mg x 2 per day for a total duration 6 weeks, i.E.Until (b)(6) 2020.On (b)(6) 2020, there was no valve disinsertion, but thickened valve cusps with a surface area of 1.3cm² (3d planimetry) and vmax 3 m/s on average was observed.On (b)(6) 2020, echocardiography showed a moderately stenotic aortic valve (mean gradient 23 mm hg, maximum speed 3 m/sec) that was non-leaking.Transthoracic echocardiography showed posterior pseudo aneurysm without visualized fistulation.Mitral insufficiency was stable; moderate grade ii by restriction of the posterior leaflet.No increase in left ventricular filling pressures.Left ventricle slightly dilated (57 mm in tele diastole, 42 mm in tele systole).Fraction satisfactory left ventricle ejection, at 54% in biplane at 50% visually.Undulated straight cavities.No indirect sign of high blood pressure.No pericardial effusion.The valve remains implanted.The patient status is unknown.No additional information was provided.
