What is basal interventricular septum?
The interventricular septum (IVS, or ventricular septum, or during development septum inferius) is the stout wall separating the ventricles, the lower chambers of the heart, from one another.
What are the parts of interventricular septum?
The right aspect of the muscular ventricular septum can be designated as having 3 components corresponding to the three portions of the ventricle: inlet, apical trabecular, and outlet.
Which nodes are located in the interventricular septum?
In general, the atrioventricular node is located in the so-called floor of the right atrium, over the muscular part of the interventricular septum, inferior to the membranous septum: i.e., within the triangle of Koch, which is bordered by the coronary sinus, the tricuspid valve annulus along the septal leaflet, and the …
Where is the interventricular septum in the heart?
Interventricular Septum | Atlas of Human Cardiac Anatomy. Location: Medial wall of the left ventricle. This is the wall that borders septum between the left and right ventricle.
What is basal septal bulge?
Interventricular septal bulge (also known as a sigmoid septum) is a common finding in imaging studies in the elderly population and refers to an isolated thickened basal septum resulting in a sigmoid configuration.
What is the purpose of the interventricular septum?
In addition to separating the ventricles, the interventricular septum also functions as a conduit for part of the conducting system of the heart. The atrioventricular bundle of His, which arises from the atrioventricular node, arborizes within the septum to reach its target points.
How is interventricular septum formed?
The pars atrioventriculare is formed by the closure of the bulboauricular canal. The posterior smooth septum is a result of the balanced growth of the margins of the interventricular foramen. The posterior trabeculated septum develops as a result of the expansion of the two ventricles on both its sides.
How interventricular septum is formed?
What vessel transects the interventricular septum?
Right Coronary Artery
Right Coronary Artery. The RCA normally arises from the right coronary sinus and courses in the right AV groove toward the crux of the heart (the point on the posterior surface of the heart where the AV groove transects the line of the interventricular septum and interatrial septum, forming a cross).
What is function of interventricular septum?
The interventricular septum divides the right and left ventricles, running in the plane of the anterior and posterior interventicular grooves.
What is basal septal left ventricular hypertrophy?
Left ventricular hypertrophy is a thickening of the wall of the heart’s main pumping chamber. This thickening may result in elevation of pressure within the heart and sometimes poor pumping action. The most common cause is high blood pressure.
