It was reported that the procedure was performed to treat a heavily calcified, heavily tortuous lesion in the mid to proximal left anterior descending (lad) artery.
A 4.
0mm xience stent was deployed when it was noted via intravascular ultrasound (ivus) that the stent was under deployed.
The physician then used a 5.
0x12mm nc trek balloon dilatation catheter (bdc) in an attempt to further post dilate the xience stent.
During removal of the nc trek, the device was reportedly either caught on a stent strut or on the guide liner, some force was applied, and the shaft snapped.
The balloon was pulled into the guiding catheter and the device was fully removed all at once.
The device was in two pieces upon removal.
There were no adverse patient effects and no clinically significant delay in the procedure.
No additional information was provided.
