5. Diamondback 360™
Coronary OAS Components
•Tortuosity: no > 2 bends > 90°
To be avoided
•Slow advancement: 1-3 mm/s(the slowest, the larger: up to 1.8 mm)
•≤30 s run
• rest period (= treatment time; longer if bradicardia/hemodynamic changes)
Procedural features:
•only large vessels
•Only after at least 2 run 80000 rpm
•No if < 3mm or tortuosity
Speed escalation (120000 rpm):
•Tactile feedback: no resistence
•Audible pitch: no changes

Ease Safety Efficacy Confidence
Editor's Notes
First of all there is a general need to support the CTO culture. Working in a cath lab where CTOs are done, attending CTO conferences, looking at expert operators promotes the knowledge of tools and techniques and the develops of a CTO mindset also in non CTO operators, that positively affects our daily routine, making easier complex PCIs, increasing procedural safety and efficacy, and avoiding potentially dangerous waste of time.
