0 relating to the septum (= a thin part dividing tissues or spaces in an organ such as the nose or heart):
Cases with ventricular septal defect which closed spontaneously have been removed from the analysis.
It is unlikely that, in this case, the aneurysmal transformation had been caused by tuberculosis, considering its frequent association with peri-membranous ventricular septal defects.
The balanced arrangement in atrioventricular septal defect with common valve is modified sometimes by hypoplasia of one of the ventricles, mostly by the left ventricle.
One patient with a preoperative diagnosis of atrioventricular septal defect with two atrioventricular orifices was found to have a common atrioventricular orifice.
There is a complete atrioventricular septal defect with both an atrial and ventricular components seen.
In four of our patients, the double orifice was found to represent an abnormality in the left valve of an atrioventricular septal defect.
The second group of children had a complete atrioventricular septal defect, and the third had complete transposition with a ventricular septal defect.
Associated malformations are frequent, and include pulmonary stenosis or atresia, atrial or ventricular septal defects and, more rarely, atrioventricular septal defect.
