Event or Problem Description
Medtronic received information that during use of a dlp coronary artery ostial cannula, it was reported that during a mvr (mitral valve replacement), avr (aortic valve replacement) and laa (left atrial appendage) in a young patient, there was a large antegrade dose with quick arrest at the onset of the case.Ai (aortic insufficiency) ostial plegia was delivered for most of the case.The surgical preference was to utilize two separate handheld dlp 30014 devices for the right and left ostia's.The customer started by initiating the right, then unclipped the left.The coronary anatomy was non-remarkable.The surgeon checked the myocardial temperature manually from time to time and found the lv (left ventricle) temperature satisfactory, but after unclamping, the heart went into intractable vt (ventricular tachycardia) with an akinetic lv (left ventricle).Eventually the customer re-clamped, gave plege and the lv (left ventricle) recovered to support off pump, although the patient lungs were flooded in the process.The patient has an open sternum on vv ecmo (veno-venous extracorporeal membrane oxygenation) currently.After the customer re-clamped, they found the likely culprit of the problem as a blocked handheld cannula.The rca cannula delivers 200cc/min at 250mmhg while the lm cannula delivers 30cc/min.It was suspected that the left ostial handheld was not completely patent and resulted in substandard myocardial protection to left side through the case resulting in severe dysfunction post operation.The patient came out of room on high dose inotropes/vasopres sors, and deteriorated to requiring ecmo for pulmonary congestion/worsening gas exchange.The device was used to complete the procedure.Medtronic received additional information that the patient passed away on december 21st after ecmo was terminated.See the attached image.Medtronic received additional information that the right cannula failed the airflow test during the manufacturing assessment.
Additional Manufacturer Narrative
Device evaluation summary: visual inspection of the two used devices showed evidence of a blockage in the tip of the device that was identified as the left-side device.Both devices were connected to a syringe filled with deionized water and when it was engaged the right-side device had good flow the left-side device had a limited/restricted flow.The reason for the return was confirmed for t he left-side device.Medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide 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.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.
