Which component helps control bleeding at the access site during PCI?

• A. Hemostatic valve
• B. Torque device
• C. Manual compression pad
• D. Guide catheter

Answer: (A)

The key idea is sealing around the catheter to prevent blood loss as devices are advanced or exchanged. The hemostatic valve is built into the introducer sheath and provides a tight seal around the catheter shaft, stopping leakage during catheter manipulation and allowing safe flushing. This active seal is what controls bleeding at the access site in real time during PCI. Torque devices are for rotating and steering catheters, not hemostasis. Manual compression pads are external measures used after sheath removal to achieve hemostasis, not during device manipulation. The guide catheter serves as the conduit to the vessel but does not seal the access site.
