Updates to Instructions for Use (IFU) concerning Erosion with the Amplatzer Atrial Septal Occluder (ASO)

St. Jude Medical would like to inform healthcare professionals on the updates to the Instructions for Use (IFU) of the Amplatzer Atrial Septal Occluder (ASO) due to concerns of tissue erosion. In rare instances, the tissue surrounding the Amplatzer ASO can erode and result in life-threatening emergencies that require immediate surgery. The potential risk for erosion has remained constant over time, with worldwide estimated incidence rate of between 0.1% and 0.3%. As a risk mitigation measure , St. Jude Medical has updated the IFU to provide guidance to physicians on the use of the Amplatzer ASO. Healthcare professionals are advised to refer to the Dear Healthcare Professional Letter for more details.
