in patients with partial av canal , the portion of total cardiac length occupied by the atrial septum did not differ from normal ( 24.8 +/- 9.9 % versus 28.7 +/- 7.9 % , p greater than 0.05 ) , but there was a deficiency of both av and ventricular septal tissue , the latter occupying only 48.2 +/- 7.0 % of total cardiac length ( versus 57.9 +/- 4.1 % in normal subjects , p less than 0.05 ) .
