It was reported that the ventricular assist device (vad) exhibited suction and low flow alarms.The patient was hospitalized and underwent surgery for aortic valve closure along with transaortic valve procedure (tap), and placed in intensive care unit (icu).Six days later the patient started standing rehabilitation.The vad remains in use.No further patient complications have been reported as a result of this event.

Manufacturer Narrative

A supplemental report is being submitted for investigation completion.Product event summary: (b)(6) was not returned for evaluation.Review of the available autologs report revealed three (3) suction alarms logged on 24/nov/2021 and thirteen (13) low flow alarms logged since 24/nov/2021.Several increases and decreases in power consumption associated with manual changes in pump rotational speed were recorded throughout the analyzed period.As a result, the reported low flow and suction events were confirmed.Additional information indicated that the patient was hospitalized and underwent surgery for aortic valve closure along with a transaortic valve procedure (tap).Per the instructions for use, aortic insufficiency is a known potential complication associated with the implantation of a vad.Based on the available information, the device may have caused or contributed to the reported event.Based on risk documentation, multiple factors may have contributed to the reported low flow and suction events including but not limited to thrombus at the inflow cannula/outflow graft, constriction at the outflow graft, poor vad filling, and/or inappropriate pump rotational speed.Possible clinical factors that may have contributed to this event include the patient¿s pre-existing history and related comorbidities, the progression of their underlying disease, issues related to the therapeutic use of anticoagulant and antiplatelet medications and the patient's complex post-operative course.There are possible patient, pharmacological and procedural factors that may have contributed to this event.Investigation of this event is completed and the file will be closed.If new information is received, the file will be re-opened and a supplemental will be submitted.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
