MAUDE Adverse Event Report: EDWARDS LIFESCIENCES EVOQUE TRICUSPID VALVE REPLACEMENT SYSTEM; PERCUTANEOUSLY DELIVERED PROSTHESES AND TRICUSPID VALVES

Model Number	9850EV48US
Medical Device Problem Code	Patient Device Interaction Problem (4001)
Health Effect - Clinical Code	Bradycardia (1751)
Date of Event	08/06/2025
Type of Reportable Event	Serious Injury
Event or Problem Description
Edwards received notification of a transcatheter tricuspid valve replacement (ttvr) procedure involving the evoque system where the physician stated that evening after implant the patient was severely bradycardic for unclear reasons.The physician ended up putting a temp wire in, but the next day the ppm (patient had ppm at time of implant) was working normally when interrogated.The patient is now in stable condition.The final valve deployment position was good.
Additional Manufacturer Narrative
The manufacturer's investigation is ongoing and a follow-up report will be submitted when the investigation is complete.
Additional Manufacturer Narrative
The following sections were updated/corrected/added: b4, g3, g6, h2, h6, and h11.Additional type of investigation codes that were unable to be added in h6: labelling review the complaint for valve interacts with conduction system was confirmed with other empirical evidence via information reported by edwards clinical specialist.The device history record review was completed.There were no non-conformances related to the issue observed or identified, and this device passed all manufacturing and sterilization inspections.Per the instructions for use (ifu), conduction system disturbance and/or heart block which may require treatment (including permanent pacemaker) are potential adverse events.Heart block and other conduction disturbances are common in patients with underlying cardiovascular disease and can be exacerbated or aggravated with standard intra-operative medications or anesthesia.Such events are related to the patient's underlying condition.Other mechanisms for conduction abnormalities could be related to coronary obstruction due to air embolism, coronary spasm and/or local edema affecting the av node.Conduction disturbances have also been documented during transcatheter cardiac procedures as a result of direct interaction with cardiac anatomy, especially in patients with underlying conduction abnormalities.Other potential causes include trauma by a guidewire or delivery system.Additionally, cardiac conduction system complications are known risks with tricuspid valve interventions due to the proximity of the atrioventricular node (av node) to the septal leaflet of the tricuspid valve.These conduction disturbances can lead to post-operative heart block, requiring pacemaker implantation.Nevertheless, a definitive root cause cannot be determined.Since no manufacturing non-conformances were confirmed and no ifu/training deficiencies were identified, no corrective/preventative actions are required.
