Guide Wire Exam Questions and
Answers
What are the three functions of a guide wire? - Answer-vascular access to coronary
arteries
lesion crossability
rail system for device delivery
Name the three primary parts if a guidewire? - Answer-distal tip
core
coating
List the benefits/trafeoffs of a large core diameter - Answer-less flexibility
more torque
more rail support
(small is opposite)
List 4 types of distal tip covers - Answer-core to tip
shaping ribbon
full spring coil
full polymer
What rail support would an IC traditionally choose for a workhorse wire?
POBA? - Answer-workhorse = moderate
POBA = light (floppy)
List the 4 categories used to describe the difference in the tip flexibility spectrum -
Answer-Light (floppy)
Intermediate
Standard
"CTO"
What is the advantage of a hydrophilic wire? - Answer-better crossability and trackability
Frontline wires are also known as what? - Answer-Workhorse Guidewire
Why would an IC pull a second wire in a case? - Answer-additional support
first GW failed: unsuccessful lesion access/crossing, damaged wire
