WebWithin seconds after birth, a flap of tissue known as the septum primum that previously acted as a valve closes the foramen ovale and establishes the typical cardiac circulation pattern. Between the two ventricles is a second septum known as the interventricular septum. Unlike the interatrial septum, the interventricular septum is normally ... WebA slight leftward shift and flattening of the interventricular septum occurred in the course of normal systolic contraction (mean +/- SEM normalized curvature at end-diastole 0.92 +/- 0.03 and at end-systole 0.85 +/- 0.02; p less than .05). Marked exaggeration of this configurational change occurred in patients with right ventricular systolic ...
