In-hospital outcomes.

	HSRA; (n= 15)	LSRA+HSRA; (n= 15)	P value
Slow flow or no reflow	4 (27)	2 (13)	0.36
Major dissection	1 (7)	0 (0)	0.31
Perforation	0 (0)	0 (0)	1.00
Side branch occlusion	0 (0)	0 (0)	1.00
Procedural MI	2 (13)	2 (13)	1.00

Values are n (%) or mean ±SD.
HSRA= high-speed rotational atherectomy, LSRA +HSRA= low-speed rotational atherectomy following HSRA, MI= myocardial infarction.
