Table 3.
Procedural and in-hospital outcome (n = 104 patients).
| SCB (n = 43) | RA (n = 61) | p 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 |
| Large dissection (>5 mm) | 6 (13%) | 1 (2%) | 0.02 |
| Perforation | 2 (5%) | 2 (3%) | 1.00 |
| Pericardial effusion | 0 (0%) | 2 (3%) | 0.51 |
| No/slow flow | 0 (0%) | 2 (2%) | 0.49 |
| Final TIMI flow < III in MB | 0 (0%) | 1 (2%) | 0.41 |
| 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 |
| Death | 0 (0%) | 0 (0%) | 1.00 |
| Myocardial infarction | 0 (0%) | 1 (2%) | 1.00 |
| Target vessel re-PCI | 0 (0%) | 0 (0%) | 1.00 |
| CABG | 0 (0%) | 0 (0%) | 1.00 |
| Stent thrombosis | 0 (0%) | 0 (0%) | 1.00 |
| Access site complications | 2 (5%) | 2 (3%) | 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.
