Manufacturer Narrative

Udi number: (b)(4).Additional manufacturer narrative: the device was not returned to edwards for evaluation as it remains implanted.If additional information is received a supplemental mdr will be submitted.Peri-procedural arrhythmias, heart block, and other conduction disturbances are common in patients with underlying cardiovascular disease and/or conduction abnormalities.They can be exacerbated with standard perioperative medications, anesthesia, and/or instrumentation of the heart.Temporary pacemakers are inserted in all patients undergoing aortic valve replacement (avr).It is not uncommon for patients to have short term/reversible periods of heart block or arrhythmias following the procedure while their heart recovers from cardiopulmonary bypass.In many cases, the temporary pm is left in the patient for a short time following the procedure and then subsequently removed prior to discharge.Following surgical aortic valve replacement (avr), new-onset bundle branch block has been reported in 16% to 32% of patients and the need for permanent pacemakers in 3% to 8% of patients.The reason for post-operative av block after surgical avr is related to injury to the cardiac conduction system during surgical excision of the adjacent diseased valve and annular tissue.The close anatomical relationship between the aortic valvular complex and the branching atrioventricular bundle explains the possible development of conduction abnormalities following prosthetic aortic valve procedures.The clinical observation was confirmed.The cause of the event cannot be determined; however, patient factors may have contributed to the event.Edwards will continue to review and monitor all events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.
