The atrioventricular septum is a septum of the heart between the right atrium (RA) and the left ventricle (LV). [1] [2]Although the name "atrioventricular septum" implies any septum between an atrium and a ventricle, in practice the divisions from RA to RV and from LA to LV are mediated by valves, not by septa.
The interatrial septum is a septum that lies between the left atrium and right atrium of the human heart.The interatrial septum lies at angle of 65 degrees from right posterior to left anterior because right atrium is located at the right side of the body while left atrium is located at the left side of the body.

[1] [3] It gives off many branches, including the sinoatrial nodal artery, right marginal artery, posterior interventricular artery, conus artery, [4] and atrioventricular nodal branch. [citation needed] It contributes the right side of the heart, and parts of the interventricular septum. [2] [5]
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
This pouch can protrude into the right atrium or the left atrium. The cause of this aneurysm is the result of abnormal, increased pressure within the heart. Even if the foramen ovale does seal shut, an aneurysm may occur, usually on the side of the right atrium. If the aneurysm stretches too far, it can narrow the opening of the inferior vena ...
The septum primum, a septum which grows down to separate the primitive atrium into the left atrium and right atrium, grows in size over the course of heart development.The primary interatrial foramen is the gap between the septum primum and the septum intermedium, which gets progressively smaller until it closes.
Medicare covers deviated septum surgery if it's medically necessary. You'll still need to pay premiums, deductibles, and coinsurance.
The right atrioventricular orifice (right atrioventricular opening) is the large oval aperture of communication between the right atrium and ventricle in the heart.. Situated at the base of the atrium, it measures about 3.8 to 4 cm. in diameter and is surrounded by a fibrous ring, covered by the lining membrane of the heart; it is considerably larger than the corresponding aperture on the left ...
