Voorbeelden van septum

• When a remnant of the interventricular membranous septum is also present, the so-called membranous flap, it lies immediately on top of the atrioventricular bundle.

• The funnel consisted of myocardium that formed a continuity between the right wall of the atrioventricular canal and the ventricular septum.

• The membranous atrioventricular septum can itself also very rarely be deficient in isolation.

• At this stage, the wider curved end of the baffle is brought down onto the remnant of the atrial septum between the atrioventricular valves.

• The distinction between the two entities depends on whether the atrial septum walls off the left atrium from the atrioventricular junction.

• The interatrial septum bulged to the left, contributing further to the huge right atrium.

• The malaligned atrial septum was widely excised to reveal a small left atrium receiving the pulmonary venous orifices and a tiny atrial appendage.

• The angiosarcoma, due to its invasive nature, required extensive resection, after which pericardial patches were needed to reconstruct the right atrium and the septum.
