The calcified lesion modification devices according to its location and OCT calcium score.

Calcified lesion			Strategy for lesion preparation
Deep	Calcium score ≤ 3		NC/Cutting balloon/Scoring balloon
	Calcium score 4		Intravascular lithotripsy (IVL)
Superficial	Calcium score ≤ 3		NC/Cutting balloon/Scoring balloon
	Calcium score 4	Balloon crossable	IVL/Ultra-high-pressure balloon ± RA/OA
		Balloon non-crossable	RA or OA → ± IVL/Ultra-high-pressure balloon
Nodular			RA or OA

NC, non-complaint; RA, rotational atherectomy; OA, orbital atherectomy.
