A dragonfly optis catheter was used for pci on three diseased vessels - lcx, lad, and rca lesions.The lesion in the lcx was successfully treated.The proximal lad had no tortuosity, calcification, or stenosis.The patient experienced ventricular fibrillation when the catheter was inserted into the proximal lad lesion and contrast was used.Electrical defibrillation was done and the patient stabilized.Another oct attempt was performed and when the contrast was used, the patient experienced ventricular fibrillation again.Electrical defibrillation was used again and the patient stabilized.A non-abbott device was used to complete the treatment.The rca was rescheduled to be treated two days later as elective staged pci and was successfully treated with non-abbott devices.

An event of ventricular fibrillation was reported.The results of the investigation concluded that no visual anomalies to the returned catheter were noted.However, dried contrast inside the catheter prevented flushing of the catheter to verify the reported event.Dimensional inspection revealed that the outer diameter of the window tube and shaft is consistent with the specifications.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.Based on the received condition of the device and the information provided, the cause of the reported event remains unknown.The dragonfly optis instructions for use states the following complications may occur as a consequence of intravascular imaging: coronary artery spasm, unstable angina, allergic reaction to the contrast media, arterial dissection, injury or perforation, thrombus formation, abrupt closure, or total occlusion, abnormal heart arrhythmias, embolism, acute myocardial infarction, death.
