The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no indication of a lot specific product quality issue.Based on the information provided, the reported difficulty advancing appears to be due to circumstances of the procedure.It is likely that challenging anatomical conditions caused resistance during advancement resulting in the reported issue.A cause for the reported dissection, and the relationship to the product, if any, cannot be determined.Dissection is listed in the dragonfly optis instructions for use (ifu) as a known complication that may occur as a consequence of intravascular imaging and catheterization procedures.The unexpected medical intervention, and treatment with medications were related to procedural circumstances.There is no indication of a product quality issue with respect to manufacture, design or labeling.

Event Description
|
It was reported the procedure was performed in a heavily calcified, heavily tortuous and 90% stenosed lesion in the left anterior descending artery.A dragonfly optis catheter was inserted but was unable to cross the lesion.It was then observed the catheter caused a dissection in the left circumflex.Therefore, the catheter was removed and a stent was implanted to treat the dissection.There was no clinically significant delay in the procedure.No additional information was provided.

Event Description
|
Subsequent to the previously filed report, additional information was received that the physician had written a case study article about this patient titled, "ostial circumflex dissection caused by off-track oct catheter".The guide catheter was repositioned to have a more coaxial engagement and the dragonfly optis catheter was successfully delivered to the distal lad, but a dissection was noted in the lcx.During oct (optical coherence tomography) evaluation, the patient was experiencing chest pain with unstable hemodynamics.Careful contrast injection revealed the above-mentioned dissection at the ostial-proximal part of lcx with compromised antegrade flow.Double-kissing culotte stenting at the left main bifurcation was performed as treatment.The patient was then stabilized.The final angiogram and 3-dimensional oct showed good results.No additional information was provided.
