  1. 1What are two different types of grafts?Bio prosthetic valves, mechanical valves
  2. 2What are 3 types of bio prosthetic valves?Auto-graft, homografts, heterografts
  3. 3What are 3 types of mechanical valves?Ball and cage, tilting disc, bileaflet tilting disc
  4. 4Self to self (graft)Auto graft
  5. 5What two ways can you do a Auto- graft?Utilize the PV annulus and trunk and transfer to the AOV position, Fascia Lata
  6. 6What is it called when a band that is placed on the PV?Ross procedure
  7. 7Can a Fascia Lata also be used as a bioprosthetic valve?Yes
  8. 8Are fascia Lata commonly used?No
  9. 9This is a type of graft that is made from thigh muscle coveringFascia Lata
  10. 10This type of graft is used from human to humanHomograft
  11. 11Where do we get a homograft valve from?Human Cadaver donors
  12. 12Are the durability of the homograft vales as comparable to the porcine and bovine tissue valves?Yes
  13. 13This is a valve that goes from animal to human?heterograft
  14. 14What type of graft uses pigs trileaflet AOV?Porcine
  15. 15What are two types of heterografts?porcine, bovine
  16. 16Can porcine valves be stented or unstented?Yes
  17. 17What are 3 other names for a procine graft?Hancock, carpenter edwards, intact
  18. 18This graft utilizes a cows pericardium and prepares a trileaflet valve mounted on stents and sewing ring?Bovine
  19. 19What are some common names for Bovine?Carpenter-Edwards, lonescu-Shiley
  20. 20Is a Lonescu-Shiley graft still used in the US?No
  21. 21List some complications of a Bioprosthetic valve?Calcification/ degeneration, Thrombus, Infective Endocarditis, Regurgitation, Perivalvular leak, Dehiscence, abnormalities of the valve annulus
  22. 22Are all valves inherently stenotic?Yes
  23. 23What does the stenotic degree depend on?Type, Size, Shape, site
  24. 24What should you use to calculate the level of stenosis?Valve area and pressure gradients
  25. 25These are commonly found trapped on stents or leaflets, and can cause a total obstruction or stenosis?Thrombus
  26. 26Are thrombus common on Bioprosthetic valves?No
  27. 27Is it common to find regurgitation, and what is considered normal?Yes, a small jet is considered normal
  28. 28Leaking around the bioprosthetic valvePerivalvular Leak
  29. 29Why can there be leaking around a bioprosthetic valve?Usually due to gaps in the sewing or sutures
  30. 30What is it called when there is a rocking of the valve, and why does it occur?Dehiscence, due to the sewing of the valve loosening up
  31. 31What does a Dehiscence generally cause?The sewing to break, thus causing a perivalvular leak
  32. 32What are 3 types of Mechanical Valves?Ball and Cage, Tilting Disc, Bileaflet tilting disc
  33. 33This mechanical valve is a ball within a cageBall and cage
  34. 34What is the most common brand of ball and cage valve?Starr-Edwards
  35. 35True/ Fase: It is possible for a ball and cage valve to function for 20 yrs?True
  36. 36This mechanical valve is a single tilting disc that creates a major and minor orificeTilting Disc
  37. 37What is a common brand name for a tilting disc valve, and what are some other brands?Bjork Shiley (common), Metronic Hall, Wada-Cutter, Lillehei Kaster
  38. 38Are Bjork Shiley valves still used in the US? Why?No, due to a problem with strut fracture
  39. 39This mechanical valve is two discs creating 3 orifices?Bileaflet tilting disc
  40. 40What is a benefit of a bileaflet titling disc?Promotes Central Flow
  41. 41What is the least Stenotic mechanical valve?Bileaflet tilting disc
  42. 42What is the most common brands for a bileaflet tilting disc?St. Jude
  43. 43List some complications of a mechanical Valve?All valves are inherently stenotic, Thrombus, Pannus, Infective endocarditis, Regurgitation, Dehiscence, perivalvular leak, ring abscess, mechanical failure, hemolysis
  44. 44A fibrous ingrowth of tissue that can lead to regurgitation and stenosis?Pannus
  45. 45What does a Pannus result in?Leaflets are unable to open/ close correctly
  46. 46What is the etiology of mechanical/ Bioprosthetic valves?Valvular Stenosis, valvular Reguritation, Native valve Endocarditis, Aortic Dissection, Valve Repairs with valvular rings
  47. 47What are some common names of MV valve repairs?Carpentier Rings, Duran rings
  48. 48What pts are likely to recieve a Mechanical valve?Children and yound adults, pts with renal failure and small valves, pts requiring aortic root replacement due to aortic dissection
  49. 49Why are women who are in child bearing years not given mechanical valves?They want to avoid being put on blood thinners
  50. 50What pts are likely to recieve a Bioprosthetic valve?elderly pts where long term durability is less important, when you don't want anticoagulation, and when there is an increased risk for thromboembolism
  51. 51What do you do when you are evaluating a Bioprosthetic valve?Evaluate leaflet mobility and thickness, evaluate LV function,
  52. 52True/ False: A TEE is not useful when evaluating for vegetations and thrombiFalse
  53. 53List some complications you want to rule out when evaluating a Bioprosthetic valve?Calcification, Degeneration, Stenosis, Thrombus, Infective Endocarditis, regurgitation, Perivalvular leak, Dehiscence, Annulus abnormalities
  54. 54When you are looking at a mechnical valve in echo, what do you evaluate for?evaluate disc motion, rule out possible complications
  55. 55Why is 2D evaluation of a mechanical valve limited?Artifact/ Shadowing
  56. 56What complications can you have with a mechanical valve?Pannus growth, mechanical failure, and (same as bioprosthetic complication)
  57. 57What is a good way to distinguish between mechanical and prosthetic valves?Artifact
  58. 58This is a highly refelctive artifact that creates bright lines shining down from the valveReverberations
  59. 59What is m-mode used for when looking at a replaced valve?Evaluating poppet/ disc motion
  60. 60What do you use doppler for when evaluating a replaced valve?Regurgitation
  61. 61What are some treatments for valve replacements?Serial echoes to evaluate valve, replace valve, and pts with mechanical valves must take anticoagulation medicine
  62. 62What is a type of anticoagulation medicine?Coumadin
