In CSI cost reduction, which statement best reflects device usage?

• A. One OAS can treat multiple lesions
• B. Fewer adjunctive devices are required
• C. Shorter procedure time
• D. Higher bail-out stents requirements

Answer: (A)

In CSI cost reduction, the key idea is to minimize the number of devices used during a procedure while still effectively treating the lesions. Using one OAS to treat multiple lesions directly demonstrates efficient device usage: a single outer access system is employed to address several target sites, avoiding exchanges or additional devices for each lesion. This lowers hardware consumption, reduces supply costs, and can shorten overall procedure time tied to device handling.

The other points are less about how devices are used. Using fewer adjunctive devices is related to overall equipment choices but doesn’t necessarily show one device handling multiple lesions. A shorter procedure time is helpful but doesn’t inherently reflect device usage patterns. A higher bail-out stent requirement would increase, not reduce, device usage and costs.
