Manufacturer Narrative

Per the instructions for use (ifu), conduction system defects (heart block) which may require a permanent pacemaker are potential adverse events associated with balloon aortic valvuloplasty, deployment of the prosthetic valve, and the overall tavr 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 provide an explanation for these complications of the tavr procedure.According to literature review, and as documented in ts 39236 ¿clinical technical summary for complaints-conduction disturbances/ heart block¿, atrioventricular conduction disturbances after tavr 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, tavr may cause conduction abnormalities through mechanical impingement of the conduction system by the prosthesis.The mechanisms of the development of heart block after tavr are well documented and described in the literature.It is also documented that pre-existing heart block is common in patients undergoing tavr 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 device malfunction contributed to this adverse event.The reported event was unable to be determined, but have been due to procedural factors listed above and/or patient factors not provided.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 on a monthly basis, 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.Long, ashleigh, and paul mahoney."sequential use of alcohol septal ablation and electrosurgical leaflet resection prior to transcatheter mitral valve replacement." j invasive cardiol 32.2 (2020): e36-e41.

Event Description

As reported via the article "sequential use of alcohol septal ablation and electrosurgical leaflet resection,¿ post implant of a 26 mm sapien 3 valve in the mitral position via transseptal approach an intermittent complete heart block was observed.Placement of a dual-chamber pacemaker pod 1 corrected the heart block.The patient was stable post procedure and discharged home on pod 4.
