Table 1 Patient numbers, baseline characteristics, and anatomical challenge.
| Silverway | Radifocus | |
|---|---|---|
| # Randomized | 49 | 51 |
| # Cross-over* | 2 | 4 |
| # Excluded** | 2 | 2 |
| # Final analysis | 47 | 49 |
| Age | 73±11 | 73±10 |
| Male | 14 (29%) | 22 (43%) |
| Diabetes | 7 (14%) | 10 (20%) |
| Hypertension | 40 (82%) | 37 (73%) |
| Tortuosity | 25 (53%) | 28 (57%) |
| Spasm | 12 (26%) | 14 (29%) |
| Looping | 2 (4%) | 4 (8%) |
| Stenosis | 4 (9%) | 1 (2%) |
| Spasm and tortuosity | 4 (9%) | 2 (4%) |
| * Mandatory cross-over to other study wire after failure of assigned study wire; ** patients were excluded from final study analysis if both study wires failed to pass the anatomical obstacle within the pre-defined time limit. | ||
