4. Use of an ultrasonic contrast method in the diagnosis of postulated. Misplaced interatrial septum as a cause for this anomaly was mentioned2' 22 but was excluded on the basis that the orifice of the inferior vena cava and coronary sinus would also be located on the left atrial side of the septum if this occurred.2';Kerber, R.E.; Kloschos, J.M.; Lauer, R.M.;Am J Cardiol; More than normal leftward or cephalic displacement of the sinus venosus postulated by Kirsh and associates2' may not produce this anomaly unless associated with a shift of the embryological interatrial septae (septum spurium, primum, and secundum) to the right of (or caudal to) the common cardial vein. Persistence of the cephalic portion of the right valve of the sinus venosus as suggested by valvular regurgitation and intracardiac shunts,1974
