7. What anticoagulation strategy should be
used for ad hoc TRI?
1. Increase the total heparin dose
to 80-100 units/kg
2. Switch to bivalirudin
8. Transitioning to bivalirudin in ad hoc
transradial procedures:
divide the heparin dose
• Divided dosing with unfractionated heparin
should provide the same protection against post-
procedure radial occlusion as the standard 5000
unit single dose if diagnostic only procedure .
• The safety profile of bivalirudin should not be
altered if it is given after an initial reduced
heparin dose should PCI be required.
13. Does TRI and Bivalirudin combination
reduce
all procedure-related bleeding?
