Prosthetic valves Flashcards
1
Q
2 main types of prosthetic heart valves
A
bioprosthetic and mechanical valves
2
Q
how long do mechanical valves last
A
a looooooong time
and durable 30+ yrs
3
Q
mechanical valves causes an increase risk of
A
blood clots
4
Q
how long do bioprosthetic valves last
A
10-15 yrs
5
Q
type of bioprosthetic valves
A
homograft
autograft
heterograft
6
Q
homograft
A
from another human to you
7
Q
autograft
A
from yourself to yourself
aka from thigh tissue
8
Q
heterograft
A
from animal to you
bovine or procine valves
9
Q
complications from bioprosthetics
A
- calcification
- inherently stenotic
- thrombus
- endocarditis
- regurg
- perivalvular leak
- dehiscence (valve rocking)
10
Q
types of mechanical valves
A
- ball and cage or starr edwards
- st jude or bi leaflet tilting disk
3.tilting disc or bjork shirley
11
Q
mechanical valve complicatons
A
- calcification
- inherently stenotic
- thrombus
- endocarditis
- regurg
- perivalvular leak
- dehiscence (valve rocking)
- mechanical failure
- hemolysis
12
Q
what is dehiscence
A
valve rocking due to sutures ring loosen or breaking
13
Q
is m mode useful for evaluating the prosthetic valves
A
YESSSSSSS the poppet/disc motion
