Histological organization of the right and left atrioventricular valves
of the chicken heart and their relationship to the atrioventricular Purkinje ring and the middle bundle branch.
The length of right atrioventricular (AV) valve and left cusp of left atrioventricular valve
(AV) were longer in chick embryos belonging to control group as compared to those in experimental group but this was not statistically significant.
The cleft of the left atrioventricular valve
was repaired with interrupted sutures.
Figure-2: Day 10 control chick heart showing two cusps of left atrioventricular valve
(1), interatrial septum (IAS), interventricular septum (IVS), right atrioventricular valve
(2), left atrium (LA), right atrium (RA ) left ventricle (LV ) and right ventricle (RV) (low magnification - 4x) Hematoxylin and Eosin staining.
While the atrioventricular valve
insufficiencies were analyzed, the medium and advanced insufficiencies were evaluated.
This study present a right atrioventricular valve
bicuspid, whit a clearly septal component with one valvule, and a mural component with a wide anterior valvule and a small anteroseptal commissural cusp.
LAVA--left atrioventricular valve
atresia, LC--levocardia, LPSVC--left persistent superior vena cava.
The structure of left atrioventricular valve
apparatus is composed by the mitral annulus, mitral valve leaflets, chordae tendineae and papillary muscles and has been studied elsewhere (Silverman & Hurst, 1968; Lam et al.
Traumatic injuries of heart reported before are atrioventricular valve
insufficiency, aortic insufficiency, VSD, atrial septal defect, coronary artery injury, hemopericardium, cardiac rupture and cardiac contusion (3, 4).
So, it became possible to inspect all the cardiac cavities, atrioventricular valves
, other tumoral formations, tumor fragments and atrioventricular valve
They are particularly associated with atrial septal defects and with severe atrioventricular valve
Anatomy of the right atrioventricular valve
(valva atrio-ventricularis dextra or valva tricuspidalis).
