• 

  Atrioventricular Canal: Gross right ventricular view of canal defect

• 

  Atrioventricular Canal: Gross left ventricle view of canal defect (very good example)

• 

  Atrioventricular Canal: Gross (an excellent example of very large lesion)

• 

  Atrioventricular Canal: Gross infant heart (well shown)

•

  Atrioventricular Canal

• 

  Atrioventricular Canal: Gross patch repair of defect seen from left side showing left atrial portion extending into a cleft mitral valve

• 

  Atrioventricular Canal: Gross corrected defect with patch viewed from left side atrium and cleft mitral valve

• 

  Atrioventricular Canal: Gross fixed tissue opened LV showing large A component and apparently small V component now repaired with a patch of pericardium single valve case 11mo old male operative death

• 

  Atrioventricular Canal: Gross fixed tissue close-up view of A and V components closed with pericardial patch photo shows deformed left atrioventricular valve leaflet up ( a close view and very good demonstration)

• 

  Atrioventricular Canal: Gross fixed tissue rather good view of this lesion from the opened left atrium and ventricle

•
