A Novel Rotablator Technique (Low-Speed following High-Speed Rotational Atherectomy) Can Achieve Larger Lumen Gain: Evaluation Using Optimal Frequency Domain Imaging

Table 1

In-vitro experiment.

	HSRA (n= 5)	LSRA (n= 5)	P value
Pecking motion times	72.2 ±10.8	133.6 ±20.4	0.0001
Procedural time (sec)	55.2 ±14.2	89.4 ±13.9	0.01

Values are mean ±SD.
HSRA= high-speed rotational atherectomy and LSRA= low-speed rotational atherectomy.
