Question 3

For the Edwards Sapein 3 valve, what are the sheath sizes when they are deployed?

Answer 3

14 or 16 French

Question 4

For the Edwards Sapein 3 valve, what are the minimum artery dimensions?

Answer 4

Question 5

What is the major difference of the Medtronic Evolut R compared to the Edwards Sapein 3 valve?

Answer 5

Metronic Evolut R = Self Expanding Frame (Allows for capture and repositioning)

Question 6

For the Medtronic Evolut R, what is the frame made of?

Answer 6

Nitinol (Nickel)

Nitinol is a metal alloy of nickel and titanium with unique properties, including superelasticity or pseudoelasticity and “shape memory” properties. That means nitinol can remember its original shape and return to it when heated. It also shows great elasticity under stress
