Structural Heart Interventions

Question 1

What are the 2 major TAVR devices that are used in common practice?

Answer 1

1. Edwards Sapien 3
2. Medtronic Evolut R

Question 2

For the Edwards Sapein 3 valve, what are the available sizes?

Answer 2

20

23

26

29

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

5.5 mm or 6 mm

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) with porcine pericardial tissue

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

Question 7

the valve design of Medtronic Evolut R allows for what?

Answer 7

Larger EOAs

Supra-Annular Valve Design

Question 8

What are the available sizes of medtronic Evolut R?

Answer 8

23

26

29

34

Question 9

What pericardial tissue is the Edwards Sapien 3 valve made of?

What pericardial tissue is the Medtronic Evolut R valve made of?

Answer 9

Edwards Sapien 3 = Bovine Pericardial Tissue

Bovine collagen originates from a cow

Medtronic Evolut R = Porcine Pericardial Tissue

Porcine collagen originates from a pig
