Manufacturer Narrative

This device is used for treatment not diagnosis.The ventricular assist system is indicated for use as a bridge to cardiac transplantation and destination therapy in patients who are at risk of death from refractory end-stage left ventricular heart failure.The system is designed for in-hospital and out-of-hospital settings.Medtronic was made aware of this event through a search of literature publications.It was not possible to ascertain specific device information from the literature publication or to match the event with previously reported events.This information is based entirely on journal literature.All information provided is included in this report.Patient information is limited due to confidentiality concerns.Multiple patients and multiple manufacturers were noted in the article; however, a one to one correlation could not be made with unique device serial numbers.The baseline gender/age of the patients represented in the article is male/54 years old.Without a lot number or device serial number, the manufacturing date cannot be determined.Since no device id was provided, it is unknown if this event has been previously reported.Request for additional information will be made and upon receipt a supplemental report will be submitted accordingly.Referenced article: performance of noninvasive assessment in the diagnosis of right heart failure after left ventricular assist device.American society of artificial internal organs journal, july 2019; 65(5):449-455.Doi: 10.1097/mat.0000000000000830.Additional information has been requested regarding the cause of the events, but it was not available at the time of this report.If additional information is received, the event will be updated and a supplemental report will be sent.Investigation of this event is pending and a supplemental report will be sent upon its completion.If information is provided in the future, a supplemental report will be issued.

Event Description

A journal article was reviewed which contained information regarding ventricular assist devices (vads).The article compared right heart catheterization results versus non-invasive diagnostic assessments in determining which patients on vad support could be determined to be in right heart failure.Multiple patients and multiple manufacturers were noted in the article; however, a one-to-one correlation could not be made with unique device serial numbers.Based upon right heart catheterization data, echocardiography, serum laboratory analyses and physical examination, it was noted that some of the patients on vad support who were studied exhibited right heart failure with findings of peripheral edema, ascites, renal impairment and hepatomegaly.The status of the vads is unknown.No further patient complications have been reported as a result of this event.
