30 paź 2023 · The interatrial septum is a thin fibromuscular wall situated between the right and left atria of the heart. In adults, the interatrial septum has a centrally positioned depression known as oval fossa. This depression marks the place where foramen ovale was placed during fetal development.
Abstract. The interatrial septum (IAS), a fibromuscular structure separating the right (RA) and left (LA) atrium, plays an important role in both intra- and interatrial conduction. Electropathological changes in the IAS such as discordant activation of the right and left septal layer and conduction disorders may facilitate intraseptal re-entry ...
22 paź 2021 · Atrial Septation. Atrial septation begins with the appearance of a thin crescent ridge of connective tissue that grows from the atrial roof and is called septum primum (SP). The free edge of the SP is covered by mesenchymal cells (mesenchymal cup).
2 mar 2023 · The septum of the heart is a wall of tissue that separates the left and right sides of the heart and enables blood to flow as it should. It consists of the atrial septum and the ventricular...
18 lut 2018 · This article reviews the developmental aspects of the partitioning of the primitive atrium into right and left atrial chambers, the anatomical components of the atrial septum, and deficiencies that produce the various types of interatrial communications.
18 mar 2024 · The interatrial septum is a thin wall of tissue that separates the right and left atria of the heart. In adult life, its main function is to separate the two atrial chambers so that there is no shunting of blood between them.
Clinical anatomy of the atrial septum with reference to its developmental components. Clin Anat 1999;12:362–74. A review of the structure of the atrial septum, emphasising that the so-called “septum secundum” is no more than an infolding of the atrial roof.
