Manufacturer Narrative

The device was not returned to edwards for evaluation as it remains implanted.The device history record (dhr) was unable to be reviewed as the device serial number is unknown.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.A definitive root cause could not be determined.Edwards lifesciences will continue to monitor all reported events.No further actions are required at this time.
