Delayed stent deformity is a very rare complication. We attempted to dilate the lumen within the crushed stent, but were unsuccessful even after laser atherectomy. At this point, we opted to place a new stent within the deformed old stent. In this case, intravascular ultrasound was extremely useful in guiding its diagnosis and management.
