Avian heart anatomy differs in many aspects from its mammalian counterpart, but the RVOT is similar in both taxonomic groups, (10) except that the singular right atrioventricular valve functionally replaces the supraventricular crest.

In these patients substantial atrioventricular valve regurgitation is often present and associated with an increased preload and is felt to be an ominous sign of impending ventricular failure [21-23].
The contribution of the inferior endocardial cushion of the atrioventricular canal to cardiac septation and to the development of the atrioventricular valves: study in the chick embryo.
Stenosis of the atrioventricular valves is probably the result of partial fusion, while atresias of the atrioventricular valves probably results from complete fusion of that tissue (Van Mierop & Kutsche, 1990).
The substrate for pacemaker syndrome is atrial contraction against closed atrioventricular valves (mitral and/or tricuspid) which can trigger a series of adverse haemodynamic and neurohumoral disturbances.
Congenitally corrected transposition of the great arteries (CCTGA) is characterized by transposed great arteries and inverted ventricles, atrioventricular valves, and conduction system but normal atrial situs.
Triggers for premature ventricular complexes (PVCs) and IVT are mostly located at the right and left ventricular outflow tract, the His-Purkinje fibers system, and atrioventricular valves. Some regions such as papillary muscles and anterior wall of the right ventricle also account for the triggers of PVCs and IVT.
So, it became possible to inspect all the cardiac cavities, atrioventricular valves, other tumoral formations, tumor fragments and atrioventricular valve abnormalities.
The atrioventricular valves could be visualized 96% of the time, the aorta and pulmonary artery 95% of the time, and the inferior and superior vena cava 76% of the time.
