Event Description

It was reported that the patient presented with constitutional symptoms.A computerized tomography (ct) scan was performed and demonstrated stenosis at the outflow graft.An echocardiogram was also performed and revealed moderate aortic insufficiency, severe tricuspid regurgitation, and moderate mitral valve regurgitation.There was a 17 millimeters of mercury (mmhg) gradient between the outflow graft and the aorta identified that was likely at the anastomosis.Mild pulmonic valve insufficiency was also noted.A stent was deployed across the stenosis.Pre-procedure simultaneous pressures were measured with the mean gradient 32 mmhg, and repeat hemodynamics after stenting demonstrated the gradient improved to 20 mmhg.The outflow graft remains in use.No further patient complications have been reported as a result of this event.

Manufacturer Narrative

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

Manufacturer Narrative

A supplemental report is being submitted for investigation completion.Product event summary: the outflow graft was not returned for evaluation.Log file analysis could not be performed since log files c overing the reported event date were not available for analysis.The reported outflow graft stenosis event could not be confirmed due to insufficient evidence.Information provided by the site indicated that the patient presented with constitutional symptoms.A computerized tomography (ct) scan revealed stenosis at the outflow graft, and an echocardiogram revealed moderate aortic insufficiency, severe tricuspid regurgitation, moderate mitral valve regurgitation, moderately to severely dilated right ventricle and atrium, and severely reduced right ventricular systolic function; mild pulmonic valve insufficiency was also noted.A stent was deployed across the stenosis, after which the gradient between the outflow graft and the aorta improved.Based on the available information, the device may have caused or contributed to the reported event.Per the instructions for use, aortic insufficiency is a known potential complication associated with the implantation of a vad.There was no evidence that the patient had a history of aortic insufficiency.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.
