Edwards received notification of a transcatheter tricuspid valve replacement (ttvr) procedure involving the evoque system where a right ventricle (rv) perforation occurred.The delivery system remained in the patient when chest compressions were started.The patient was converted to unplanned cardiac surgery to repair rv.The patient passed on the table.Small amounts of trabeculation noted on the patient.Trace effusion noted to be the same as it was observed in screening and the patient was also noted to have pulmonary hypertension.The imaging quality was good with the images being clear and the team having bilateral access.During wire placement, wire kept popping out anteriorly.However, it was easy to adjust so procedure was continued.Wire check confirmed there was no other location for the wire.No issues inserting delivery system (ds) through left side, however, the ds was stuck at crossing with max primary on.Primary was reduced and the wire popped out again after ds crossed the annulus.After the wire was reset and noted to be good.The patient was hypotensive when placing the wire and anesthesia was having difficulty maintaining blood pressure.The team checked if an effusion had developed after crossing due to patient pressure changes.Delivery system positioning and trajectory were adjusted with secondary flex and counter clock rotation.No issues with translation were observed, ds was still deep in the rv.Nose cone was noted to be distorted, potentially caught on anatomy due to how deep the ds was in the rv.It is unknown how much wire was pushed at this point to try and gain height, but might have been very minimal if any.Wire pressure potentially was not able to be appreciated due to flouro and small rv.When wire was pushed no noticeable positional changes observed in echo or flouro.Effusion was noticed and chest compressions were performed with the ds still in the rv.After 30 minutes of treatment the ds was removed.Surgical observations were that the laceration was very large, however more likely a result of the chest compressions performed with the ds in.No other potential maneuvers could have been performed.All steps taken were as ideal as possible.

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: analysis of images, labelling review.The complaint for delivery system and/or guidewire pushed into the ventricular wall was confirmed with objective evidence based on procedural notes, imaging review and the follow-up discussion with the field team.The device history record review was completed, and this device passed all manufacturing and sterilization inspections.No nonconformance's related to the complaint event were identified.Available information suggests that suboptimal guidewire interaction during evoque tricuspid valve implantation was the primary contributor to the right ventricular (rv) perforation, compounded by challenging patient anatomy and procedural complexity.Imaging review confirmed a large pericardial effusion but did not capture the rv apex or perforation site.No fluoroscopy images were available for post-event analysis.No device malfunction was identified.The delivery system and guidewire functioned as intended.The injury was attributed to wire and delivery system interaction with rv anatomy under challenging anatomical and hemodynamic conditions, with chest compressions likely exacerbating the perforation.Since no manufacturing non-conformance's were found and no labeling, training, or ifu deficiencies were identified, no preventative or corrective actions were required.
