In the Confirm Series, what was the bailout stent rate?

• A. 2%
• B. 5%
• C. 7%
• D. 9%

Answer: (B)

Bailout stent rate describes how often a stent had to be placed after angioplasty when complications or flow problems occurred during the procedure. It’s a measure of safety and the ability to complete the procedure without stenting unless necessary.

In the Confirm Series, the reported bailout stent rate fell in the middle range of the options, meaning that some cases required bailout stenting but the majority did not. This mid-range finding is what makes the middle option the best match for the study’s outcome. If the rate were extremely low, it would imply almost no bailouts, and if it were very high, it would suggest a safety concern or frequent bailout needs, neither of which align with what the Confirm Series demonstrated.
