Procedural and in-hospital outcome (n = 104 patients).

	SCB (n = 43)	RA (n = 61)	value
Procedural duration (min)	77.9 ± 46.3	96.5 ± 36.3	0.02
Fluoroscopy time (min)	19.4 ± 15.2	26.9 ± 12.5	0.01
Contrast amount (ml)	234.3 ± 107.1	273.0 ± 116.1	0.08

Residual stenosis > 20% in MB	2 (5%)	0 (0%)	0.17
Stent failure	0 (0%)	4 (7%)	0.14
Crossover from SCB to RA	0 (0%)	11 (18%)	0.002

Myocardial infarction	0 (0%)	1 (2%)	1.00
Target vessel re-PCI	0 (0%)	0 (0%)	1.00

Values are n (%) or mean ± SD; CABG = coronary artery bypass graft; MB = main branch; PCI = percutaneous coronary intervention; RA = rotational atherectomy; SCB = scoring/cutting balloon; TIMI = thrombolysis in myocardial infarction. Stent failure occurred in patients initially randomized to an SCB strategy, and a crossover to RA was performed. The interpretation of this finding is biased by the fact that crossover patients who were initially randomized to an SCB strategy are included in the RA group.
