Manufacturer Narrative

Date of event is an estimated date based off the aware date as the exact event date was not reported.

Event Description

It was reported that the wire fractured and the patient experienced a perforation, intramural hematoma and chest discomfort.The severely stenosed target lesion was located in the heavily calcified proximal-mid right coronary artery (rca).A 1.5mm rotalink burr, 2.00mm rotalink burr and a 330cm rotawire were selected for used.During the procedure, the burr was changed up to 2.00mm after ablation initially begun with a 1.5mm burr.During ablation, the 2.00mm burr stalled and the rotawire fractured.The fractured wire lodged into the posterior left ventricular (plv) and there was perforation and intramural hematoma in the rca.The wire was able to be removed.Two stents were deployed into the lesion which sealed the perforation.Ivus showed good seal, no significant effusion on bedside transthoracic echocardiogram (tte).Clinical decision was made to not proceed to stent the left anterior descending artery.Felodipine was commenced to reduce coronary spasm and the procedure was completed.Following the procedure, the patient endured mild constant chest discomfort, different from presenting angina.It was worse with deep inspiration and was consistent with inflammatory pericarditic etilogy.Troponin was 1417 post procedure in keeping with t4ami and tte showed left ventricular ejection fraction (lvef) of 40-45% representing trivial pericardial effusion.

Manufacturer Narrative

Date of event is an estimated date based off the aware date as the exact event date was not reported.Device evaluated by manufacturer: the device was returned for analysis.An incomplete guidewire was returned.The returned section measured approximately 123 inches from the proximal end and the other section was not returned.Microscopic inspection revealed that the guidewire separation was caused by fatigue.No more damages were encountered in the device.Dimensional inspection of the device was performed and revealed that the middle and proximal section were within specifications.However, the overall length could not be measured as the distal section was not returned.
