Event Description

The patient had a concomitant surgical procedure of aortic valve replacement and cabg (number of anastomoses: 3) through sternotomy.The patient also had an aortic endarterectomy.During the same procedure a cryoflex probe powered by a cryoconsole, and a cardioblate lp clamp powered by a valleylab ft-10 generator were used.The left atrial appendage was successfully closed.Left pulmonary vein (lpv) and right pulmonary vein (rpv) conduction block was successfully achieved.One day after the procedure, the patient experienced multisystem organ failure, which was treated with an implantable pacemaker, additional medication, a right ventricular device, renal replacement therapy, and a surgical intervention.The patient died four days later.It was reported that the patient continued to have increased lactate levels post surgery.On post-op day 1, a right ventricular device was inserted.Urine output decreased over next 24 hours.Post-op day 2, they received renal replacement therapy.Post-op day 3, they had an external pacemaker implanted for loss of underlying rhythm.The patient continued to have increased lactate, hypotension, and severe pulmonary edema.They had worsening metabolic acidosis.They had multisystem organ failure and was deemed not to benefit from left ventricular support or a mitral valve repair.The adverse event was deemed by the sponsor as possibly related to the procedure and the concomitant procedure, but not related to the study devices.Medtronic received additional information that the adverse event was deemed by the site as possibly related to the concomitant procedure, unlikely related to the procedure but not related to the study devices.Medtronic received additional information that the event that resulted in patient death was assessed by site as unlikely related to the study procedure, possibly related to the concomitant procedure and possibly related to the study devices.Medtronic received additional information that the adverse event is updated as related to the device.It was reported that the rv failure was unlikely related, and the complication was related to the surgery in general, not the ablation component.
