What is the recommended inflation time for a DCB?

• A. 15-20 seconds
• B. 30-60 seconds
• C. 60-90 seconds
• D. 2 minutes

Answer: (B)

The recommended inflation time for a drug-coated balloon (DCB) is indeed 30-60 seconds. This duration is critical for ensuring that the drug coating effectively adheres to the vessel wall, maximizing the therapeutic benefits while minimizing potential complications.

During this inflation period, the optimal drug delivery occurs as the balloon expands and the therapeutic agent is released into the tissue. A shorter inflation time may not allow adequate drug delivery, while a longer duration might increase the risks of complications such as vascular damage or unintended effects. The balance achieved in the 30-60 seconds range ensures both efficacy and safety during the procedure.
