Rotational atherectomy to pulverize a fractured microcatheter tip: Clean up after yourself!


      Microcatheter tip embolization is a rare but potentially life-threatening complication of percutaneous coronary intervention. We describe a case of microcatheter tip fracture due to aggressive manipulation in a calcified lesion. Rotational atherectomy was performed to pulverize it. The smaller remnants were then jailed by stenting. This approach might reduce the risk of acute vessel closure by minimizing debris size.
