What was the bail-out stent rate in the OASIS IDE trial?

• A. 1%
• B. 0%
• C. 2.5%
• D. 5%

Answer: (C)

Bailout stent rate shows how often a stent had to be implanted as a rescue during the procedure when the initial strategy didn’t achieve the desired result. In the OASIS IDE trial, this rate was 2.5%, meaning stenting was required in only a small minority of cases. This reflects that the majority of procedures succeeded without needing a stent. The rate is calculated as (number of bailout stents used / total patients) × 100, so 2.5% corresponds to about one patient in forty.
