THREE FIGURES

I n examining an extensive series of foetal and infant hearts for congenital defects, we became convinced that the size of the foramen ovale was a misleading index of the capacity of the interatrial communication. The valvula f oraminis ovalis seemed, with striking regularity, to be attached to the septum in such a manner that it would considerably restrict blood flow through the septa1 orifice. We were unable t o find in the literature any reference to this functionally significant condition, except the passing comment of Rnedinger ('71, p. 404):

Die ValvGla foraminis ovalis f u r den Blutstrom aus den1 rechten in den linken Vorhof in gewisser Hinsicht ein Hindernis abgibt, indem diese Klappe sich von allen ubrigen Herzklappen dadurch unterscheidet, das sie an der eirunden Oeffnung unter allen TJmstanden eine ziemlich straff e' Spannung zeigt.
