When a remnant of the interventricular membranousseptumis also present, the so-called membranous flap, it lies immediately on top of the atrioventricular bundle.From theCambridge English Corpus
The funnel consisted of myocardium that formed a continuity between the right wall of the atrioventricular canal and the ventricularseptum.From theCambridge English Corpus
The membranous atrioventricularseptumcan itself also very rarely be deficient in isolation.From theCambridge English Corpus
At this stage, the wider curved end of the baffle is brought down onto the remnant of the atrialseptumbetween the atrioventricular valves.From theCambridge English Corpus
The distinction between the two entities depends on whether the atrialseptumwalls off the left atrium from the atrioventricular junction.From theCambridge English Corpus
The interatrialseptumbulged to the left, contributing further to the huge right atrium.From theCambridge English Corpus
The malaligned atrialseptumwas widely excised to reveal a small left atrium receiving the pulmonary venous orifices and a tiny atrial appendage.From theCambridge English Corpus
The angiosarcoma, due to its invasive nature, required extensive resection, after which pericardial patches were needed to reconstruct the right atrium and theseptum.From theCambridge English Corpus
Both traps in the fourth chambers were baited with hexane-treated septa.From theCambridge English Corpus
There is continuity of the leaflets of the aortic and pulmonary valves because of absence of the outletseptum.From theCambridge English Corpus
Small-to-moderate sized muscular defects in the apical trabecularseptumoften close by growth and hypertrophy of the muscularseptum.From theCambridge English Corpus
The muscular outletseptum, and the "septal" components of the subpulmonary infundibulum, were absent.From theCambridge English Corpus
Six of the seven patients had complete deficiency of the muscular outletseptum, with the defect extending to the perimembranous area.From theCambridge English Corpus
Such complete absence of the muscular outletseptumwas not present in any of the patients without the deletion.From theCambridge English Corpus
There is posterior deviation of the outletseptumgiving rise to muscular subpulmonary stenosis.From theCambridge English Corpus
