Rotational atherectomy improves the procedural success rate of percutaneous coronary intervention (PCI) in heavily calcified lesions, but does not decrease restenosis. Late lumen loss was higher in patients treated with rotational atherectomy followed by drug-eluting stenting compared with patients without rotational atherectomy. Pericardiocentesis kits and covered stents should be readily available given the risk of coronary perforation.

Excimer laser coronary atherectomy improves procedural success but does not decrease restenosis in moderately calcified lesions. Excimer laser coronary atherectomy can be used in situations that are difficult to treat including in-stent restenosis, suboptimal stent expansion, and subtotally occluded lesions uncrossable by exchange catheters.

Routine use of thrombectomy for acute myocardial infarction (AMI) is not recommended. The benefits of up-front manual aspiration thrombectomy in AMI remain questionable, but the procedure may become necessary in bailout situations.

Embolic protection devices can capture liberated debris during saphenous vein graft (SVG) intervention to decrease the risk of distal embolization and periprocedural MI.

Embolic protection devices do not appear to protect against no-reflow or improve clinical outcomes in PCI of native coronary vessels. Embolic protection devices provide clinical benefit in SVG intervention but remain underutilized.
