Structural Heart Interventions Flashcards
What are the 2 major TAVR devices that are used in common practice?
- Edwards Sapien 3
- Medtronic Evolut R
For the Edwards Sapein 3 valve, what are the available sizes?
20
23
26
29
For the Edwards Sapein 3 valve, what are the sheath sizes when they are deployed?
14 or 16 French
For the Edwards Sapein 3 valve, what are the minimum artery dimensions?
5.5 mm or 6 mm
What is the major difference of the Medtronic Evolut R compared to the Edwards Sapein 3 valve?
Metronic Evolut R = Self Expanding Frame (Allows for capture and repositioning)
For the Medtronic Evolut R, what is the frame made of?
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
the valve design of Medtronic Evolut R allows for what?
Larger EOAs
Supra-Annular Valve Design
What are the available sizes of medtronic Evolut R?
23
26
29
34
What pericardial tissue is the Edwards Sapien 3 valve made of?
What pericardial tissue is the Medtronic Evolut R valve made of?
Edwards Sapien 3 = Bovine Pericardial Tissue
Bovine collagen originates from a cow
Medtronic Evolut R = Porcine Pericardial Tissue
Porcine collagen originates from a pig
What are the two sizes of MitraClip available?
XTR
NTR

What type of clip is used in a MitraClip?
What covering is used?
Cobalt-Chromium Clip
Polyester Cover

What are the two Left Atrial Appendage Occlusion devices on the Market?
- Watchman (Largest on the market)
- Lariat
What is the frame of the Watchman device made of?
Nitinol Frame
What is the fabric of the Watchman device made of?
Polyethylene Terephthalate (PET)
What is the most frequent major complication of Watchman device placement?
Tamponade
What are the available sizes to the Watchman Device?
21
24
27
30
33
What trans-septal puncture site is needed for MitraClip?
Posterior
Mid-Superior
RED in the picture

What trans-septal puncture site is needed for LAAO Watchman?
Posterior
Mid Interior
(GREEN)

What trans-septal puncture site is needed for LAAO Lariat?
Posterior

What trans-septal puncture site is needed for Transcatheter Mitral Valve Replacement?
Posterior
Mid Superor
(Same At MitraClip = RED)

What trans-septal puncture site is needed for Paravalvular Leak?
Depends on leak location
Posterior
Superior-Mid
(Same as MitraCLIP = RED)
