A Dear Healthcare Professional Letter has been issued by Medtronic International Limited to inform healthcare professionals about the steps to be followed prior to performing a controller exchange so that restart of the HeartWareTM Ventricular Assist Device (HVADTM) pump is not inadvertently delayed. It is recommended to power down the programmed controller and disconnect the monitor data cable before performing a controller exchange. If these steps are not followed and a patient’s driveline is connected to a controller that was not powered down after programming, the pump will not restart and this could lead to serious harm. Healthcare professionals are advised to review the current HVADTM system Instructions For Use (IFU) and follow the detailed steps in the letter for programming the HVADTM controller prior to performing a controller exchange. Please refer to the letter for details.

Only abstracts of the Dear Healthcare Professional Letters (DHCPL) are provided on this website.
