3. What Is The Mitral Valve?
 The human heart has 4 valves.
 The mitral valve connects the left atrium (LA) and the left ventricle (LV).
 The mitral valve opens during diastole to allow the blood flow from the LA to the
LV

4. How The Mitral Valve Works?
 During ventricular systole,
the mitral valve closes
 prevents backflow to the LA

5. What Is The Mitral Valve Problems?
 the two valve flaps of the mitral valve
do not close smoothly
 When the heart pumps (contracts) part
of one or both flaps collapse backward
into the left atrium
 prolapsed valve lets a small amount of
blood leak backward through the valve
 may cause a heart murmur

7. Repair The Mitral Valve
Ruptured chords at free edge of
posterior leaflet. Region to be
resected is indicated
Abnormal segment has been
removed. Leaflet edges are sewn
together.

8. Artificial Heart Valve
 medical choice may be to replace the natural valve with an
artificial valve
 This requires open-heart surgery
 There are three main types of artificial heart valves:
the mechanical,the biological, and the tissue engineered valves.

9. Types Of Heart Valve Prostheses
 Mechanical heart valve
 Percutaneous implantation
 Stent framed
 Not framed
 Sternotomy/Thoracotomy implantation
 Ball and cage
 Tilting disk
 Bi-leaflet
 Tri-leaflet
 Tissue (biological) heart valves
 Allograft/isograft
 Xenograft
 Tissue Engineered heart valves

10. Materials of Mitral Heart Valve
 Most artificial valves are made of titanium, graphite, pyrolytic carbon,
and polyester.
 The titanium is used for the housing or outer ring
 graphite coated with pyrolytic carbon is used for the bileaflets
 100% pyrolytic carbon is used for the inner ring
