Which statement describes the economic advantage of CSI over Turbohawk?

• A. Costs reduced due to lack of distal protection and closure devices
• B. Distal protection devices increase costs
• C. CSI requires more devices for multiple vessels
• D. None of the above

Answer: (A)

Focusing on how costs stack up with different interventional devices, the key idea is that ancillary equipment can drive up overall procedureExpense. Distal protection devices protect downstream vessels but add device costs and extra steps, and closure devices add their own price and procedures. If a technique or approach works without needing these extras, the per-case cost goes down. That makes the statement that costs are reduced due to the lack of distal protection and closure devices the best description of CSI’s economic advantage over TurboHawk.

The other ideas don’t fit because distal protection devices typically raise costs, and claiming CSI needs more devices for multiple vessels would increase, not decrease, costs. “None of the above” isn’t correct since there is a clear cost-saving aspect described.
