The icd and the cm devices under complaint were not returned for analysis.The analysis is therefore based on the inspection of the quality documents associated with the manufacture of this icd as well as the analysis of the available data.The manufacturing process for the icd was reviewed.All production steps had been performed accordingly.There was no sign of any inconsistency during manufacturing.The final acceptance test proved the icd functions to be as specified.The available data were evaluated, confirming the clinical observation.However, no peculiarities were observed regarding the functionality of both cm devices.Therefore, the icd data was further evaluated.The available iegms documented the presence of noise on november 7th, 2023, presumably caused by the surgery procedure.This led to 20 charging cycles, 3 of which resulted in shock deliveries, because the icd detection had not been deactivated before the surgery.Due to this occurrence, it cannot be excluded that the clinical observation might have resulted from a potential damage of the icd, caused by the aortic valve replacement procedure.However, the root cause is not determinable only based on data analysis.Should further relevant information become available, this report will be updated.
