Event Description

Per report received from australia, it was a case of an implant of a 29mm sapien 3 valve, in aortic position by transfemoral approach.The native valve was pre-dilated with an edwards 25mm bav, which caused a complete heart block post pre-dilation, and remained in it with junctional escape.It was also used a non-edwards bav following 2 attempted inflations with the edwards 25mm balloon that kept slipping with each inflation.The non-edwards bav was inflated two times that also slipped.Finally, the valve was implanted without more issues.As the patient remained in complete heart block, it was decided to implant a permanent pacemaker the following day post-procedure.The patient was not converted to surgery and was alive at the end of the procedure.The patient recovered and discharged home.As per medical opinion, the root cause of this event was due to bulky lcc calcium.

Manufacturer Narrative

Per the instructions for use (ifu), conduction system defects (heart block), arrhythmias and conduction system defects that may require a permanent pacemaker are potential adverse events associated with balloon aortic valvuloplasty, bioprosthetic heart valves, and the thv procedure.According to the valve academic research consortium (varc) guidelines, the close anatomical relationship between the aortic valve complex and the branching atrioventricular bundle may explain these complications of the thv procedure.According to the literature review, and as documented in a clinical technical summary written by edwards lifesciences , atrioventricular conduction disturbances after thv are associated with many patient-related and procedural related factors, including pre-operative co-morbid status, the degree, and bulkiness of aortic valve and annular calcification, inter-ventricular septal thickness, pre-existing electrocardiogram abnormalities, the depth of prosthesis implantation, and the profile of the implanted prosthesis.Unlike conventional avr, where there may be localized trauma due to decalcification of the annulus and/or suture placement in the proximity of the av node or the bundles, thv may cause conduction abnormalities through mechanical impingement of the conduction system by the prosthesis.The mechanisms of the development of heart block after thv are well documented and described in the literature.It is also documented that pre-existing heart block is common in patients undergoing thv or surgical avr and another 4-6 % will develop postoperative heart block, potentially requiring a permanent pacemaker.In this case, there was no allegation or indication a product malfunction contributed to this adverse event.Investigation results are inconclusive as patient and procedural factors were not provided; however, the event could be related to the mechanisms described above.A review of edwards lifesciences risk management documentation was performed for this case.The reported event is an anticipated risk of the transcatheter heart valve procedure, additional assessment of this adverse event is not required at this time.The ifu and training manuals have been reviewed and no inadequacies have been identified with regards to warnings, contraindications, and the directions/conditions for the successful use of the device.Complaint histories for all reported events are reviewed against trending control limits monthly, and any excursions above the control limits are assessed and documented as part of this monthly review.No corrective or preventative actions are required at this time.H3 other text : no return.
