It was reported that the rotawire broke and perforation occured.The 95% stenosed target lesion was located in the moderately tortuous and severely calcified circumflex artery.An ng rotawire floppy single was selected for use during a heart catheterization (coronary angiogram) and percutaneous coronary intervention (pci).During the procedure, the wire was placed into a coronary artery and was lodged into calcium and the distal part with the radiopaque marker broke off.A 6 french guiding catheter was used.Intravenous heparin was administered, and a 0.014 whisper wire was then advanced into the left main.It was rather difficult to advance a wire into the circumflex artery.Subsequently a whisper wire was advanced into the circumflex artery to cross the left main and om lesions.Then, a 1.5 mm balloon was attempted to advance into the lesion but was unsuccessful despite a telescope catheter for support.Rotablator was then used with a corsair catheter and exchanged the wire for a roto floppy wire.Once the equipment is set up, 1.25 mm per was platformed outside the body.At the same time, the patient complained of chest pain with evidence of st depression on ekg.Fluoroscopy was also done and noted vessel perforation and rotablator wire was noted to be broken off.Anticoagulation was then reversed, and the doctor from ct surgery was notified.Given the fact the patient was post prior coronary artery bypass, it was unlikely the patient would accumulate any significant pericardial effusion.A bedside echocardiogram was performed, that demonstrated no pericardial effusion.No further complications were reported.
