You answered correctly.
The correct answer is (d), all of the above. PCI of calcified lesions leads to lower technical success with greater (b) stent malapposition, and (c) edge dissection as well as worse clinical results with (a) greater restenosis. Reference: Catheter Cardiovasc Interv. 2018;91:859-866
You answered incorrectly.
The correct answer is (b) orbital atherectomy which is an extrinsically rotating burr which will follow a guidewire biased toward the inner or outer curvature of the vessel. Rotational atherectomy (a) and laser intravascular lithotripsy (b) are “central cutting devices” with rotational atherectomy functioning as a drill and laser atherectomy disrupting mild calcium circumferentially. Intravascular lithotripsy (d) circumferentially disrupts deep calcium.
You answered inorrectly.
The correct answer is intravascular lithotripsy (c) which provides segmental, circumferential penetrating energy to disrupt deep calcium. Rotational atherectomy (a), orbital atherectomy (b) and laser atherectomy (d) all are front directed ablative devices ablating superficial calcium.
