interatrial septum

The interatrial septum forms during the first and second months of fetal development.

During development of the fetus, the interatrial septum develops to separate the left and right atria.

The interatrial septum is the wall of tissue that separates the right and left atria of the heart.

Myxomas are typically pedunculated, with a stalk that is attached to the interatrial septum.

Normally, the right and left atria are separated by a septum called the interatrial septum.

The interatrial septum is punctured and the catheter passed into the left atrium using a "trans-septal technique."

The most common location for attachment of the stalk is the fossa ovalis region of the interatrial septum.

"Bezold's ganglion": an aggregation of ganglion cells in the interatrial septum.

An atrial myxoma is a benign tumor of the heart, commonly found within the left and right atria on the interatrial septum.

Atrial septal defect is a relatively common heart malformation that occurs when the interatrial septum fails to develop properly.

There is also a fossa ovalis in the interatrial septum, which is used in the fetal period as a means of bypassing the lung.

Defects in the interatrial septum or the interventricular septum allow blood to flow from the right side of the heart to the left, reducing the heart's efficiency.

Gerdy's interatrial loop: A muscular fasciculus in the interatrial septum of the heart, passing backward from the atrioventricular groove.

Defect in the interatrial septum that permits blood flow between atria, including a patent foramen ovale (PFO).

The construction of a heart void of an ASD prevents interatrial communication by means of an uncompromised interatrial septum.

The AV node receives two inputs from the atria: posteriorly, via the crista terminalis, and anteriorly, via the interatrial septum.

'Atrial septal defect' ('ASD') is a form of congenital heart defect that enables blood flow between the left and right atria via the interatrial septum.

Fossa ovalis: remnant of the closure of an opening that was present within the interatrial septum of the fetal heart (normal) where it is called the foramen ovale.

Apart from Bachmann's bundle these are the anterior interatrial septum, posterior interatrial septum, and the coronary sinus.

It is located at the center of Koch's Triangle-a triangle enclosed by the septal leaflet of the tricuspid valve, the coronary sinus, and the membraneous part of the interatrial septum.

The bundle of His is an important part of the electrical conduction system of the heart as it transmits impulses from the atrioventricular node, located at the inferior end of the interatrial septum, to the ventricles of the heart.

Cystic tumour of atrioventricular nodal region (CTAVN) CTAVN is of endodermal origin and occurs exclusively in the area of the AV node, tricuspid valve, and interatrial septum.

Other famous examples of Vesalius disproving Galen in particular was his discovery that the lower jaw was only one bone, not two (which Galen had assumed from animal dissection) and his proof that blood did not pass through the interatrial septum.

The AV node is an area of specialized tissue between the atria and the ventricles of the heart, specifically in the posteroinferior region of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles.
