It was reported that a dragonfly optis imaging catheter was advanced to a lesion in the right coronary artery (rca) with moderate calcification and high tortuosity.It was noted resistance was felt due to the calcification.A decision was made to retrieve the catheter to pre-dilatate the lesion.However, the imaging catheter could not be retrieved due to the calcium, stenosis and tortuosity.After some time, the imaging catheter was able to be pulled out and removed safely.Then the lesion was pre-dilated with several unspecified balloons and the same imaging catheter was re-advanced to check the lesion.However, the image was not normal which indicated that the imaging catheter was damaged due to the calcification.Therefore, the imaging catheter was removed and the procedure continued with another unspecified imaging catheter and the lesion was treated with a drug-coated balloon to complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
