Interatrial septal aneurysm or atrial septal aneurysm (ASA) is defined as an abnormal protrusion of the interatrial septum. The exact length of the protrusion that defines an interatrial septal aneurysm varies in the literature, ranging from >11 mm to >15 mm beyond normal excursion in adults 4,5 and 5 mm in children.. It can be limited to the fossa ovale or involve the entire inter-atrial septum. Lipomatous hypertrophy of the interatrial septum (LHIS) is a relatively uncommon disorder of the heart characterized by benign fatty infiltration of the interatrial septum. It is commonly found in elderly and obese patients as an asymptomatic incidentally discovered finding. 2017-07-23 2018-07-28 The interatrial septum is a thin structure best visualized by transesophageal echocardiography but is also readily seen on transthoracic imaging, particularly in the subcostal view.

Interatrial septum

The interatrial septum is the thin wall that separates the upper atrial cavities of heart.

Look it up now! The AV septum is contiguous with the true interatrial septum, and its regional anatomy is important for electrophysiologists to understand when avoiding inadvertent damage to the compact AV node. In general, if the ablation catheter is ventricular and not on the mid portion (anterior or posterior septum), delivering energy is usually safe. (C) Color flow Doppler interrogation of hypermobile interatrial septum in A and B revealed transient left-to-right shunt (arrow) via a patent foramen ovale. the venous system to lodge in the systemic arteries, although the actual passage of a thromboembolus through a PFO is only rarely captured on echocardiography views (Fig. 9; please see companion DVD for corresponding video). 2021-02-08 · Each interatrial channels (IACs) was classified as either an open or obstructed channel according to the connection of each hole on the right and left surfaces of the interatrial septum.

the venous system to lodge in the systemic arteries, although the actual passage of a thromboembolus through a PFO is only rarely captured on echocardiography views (Fig. 9; please see companion DVD for corresponding video). Imaging description Atrial septal aneurysms (ASA) appear as a thin-walled, round or lobulated outpouching located at the fossa ovalis. They are formed by redundant tissue of the fossa ovalis that protrudes ≥ 10–15 mm beyond the plane of the interatrial septum with a base ≥ 15 mm in width (Figure 18.1). The atrial septum is the membrane that separates the left and the right upper chambers of the heart (the atria). By definition, when the atrial septum travels abnormally into either or both of the atria with each heartbeat, it is considered to have an aneurysm. In all patients the interatrial septum had a bilobed or dumbbell shape that is typical of LHIS (Figs.
