Observation of Anatomical Structures of the Interatrial Septum and the Interventricular Septum of Goat Heart

Objective To observe and measure the morphology and position of the interatrial septum and the interventricular septum of the goat heart to provide comparative anatomy data for study of heart.Methods The oval fossa and the interventricular septum of goat heart were observed by gross anatomy method.Results The oval fossa was 9.63±2.18 mm long and 6.85±1.54 mm wide.The distance of center point of oval fossa to the center point of coronary sinusal ostium, to the middle point of septal tricuspid valve, to the middle point of anterior biscuspid valve was 9.09±2.10 mm, 12.81±2.34 mm, 8.94±2.65 mm resptetively. The thickness of the superior edge of the oval fossa was 1.26±0.50 mm, its inferior edge was 1.80±0.40 mm, the anterior edge was 2.39±1.78 mm, the posterior edge was 2.29±0.89 mm in thick. The anterior part of the membrane portion of interventricular septim was 2.94±1.13 mm wide, the middle part 4.66±1.15 mm wide, the posterior part of it 6.13±1.41 mm long and 9.62±1.83 mm wide, the inferior edge 15.06±2.63 mm long. The superior, anterior and posterior edges of the muscle portion of the interventricular septum were 37.63±4.48 mm, 52.84±6.22 mm and 33.77±2.96 mm long respectively, and the thickness was 9.34±1.69 mm.Conclusion The interatrial septum and interventricular septum of the goat heart were similar to those of human being a good material for the repairment of coloboma of the interatrial septum and the interventricular septum.
