An agfa clinical analyst performed a retro-analysis and reported the findings to agfa service and agfa product quality manager.Agfa's investigation into this occurrence of rmat customizations has revealed that this specific change had the potential to introduce clinical inaccuracies in patient reports.Specifically: the original sentence of: "the mean gradient of the aortic valve is" has been changed to: "there is severe aortic stenosis".In this issue, the intent of the reading physician is to describe the mean gradient measurement would be added to the notes section although there is nothing in the diff or the summary to provide evidence for that assumption.The sentence change however, changes the original intent from quantifying the av mean gradient to indicating the severity as is severe.This change is different clinically and would not reflect the intent of the original reading cardiologist as the mean gradient might not clinically indicate a diagnosis of severe as and could lead to misdiagnosis and/or inappropriate treatment.Potential impact: if the change was made after reports had been generated with the original sentence selected, those reports prior to the change could display incorrect clinical data if viewed in rm or if used as a template for a repeat study on that patient.There has been no reported patient harm for this occurrence.A reportable correction is underway for this issue and has been reported to the fda via reference #z-2112-10.Agfa will follow the rmat post market verification work instructions to correct the sentence finding.Any further investigation for the site described in this report will be documented in the ongoing cfr part 806 reporting.(b)(6).
