Slender Catheter Advantages
• Reduce the use of contrast dye about 14%
• Shorten hemostatis time about 1.4 hours
• Lessen any access site complication such
as bleeding and artery occlusion
compared with 6Fr guiding catheters
4Fr guiding catheters

measuring fractional flow reserve.
• We can make ad-hoc percutaneous coronary
intervention with 4-french guiding catheters.
