Abstract:
Five ASQ extraction cases from our hospital were showed in this list. All leads were completely removed and there were no serious complications. Laser sheaths were used in four of the five cases. In cases 2 and 4, LV leads were successfully reimplanted after the removal of the ASQ, and the original target branches where the ASQ had been implanted remained patent.
