In other cases, accessory path allows rapid conduction of a supraventricular tachyarrhythmia to the ventricles. Careful analysis of the … WebbThe foramen ovale often closes at birth. At birth, when the lungs become functional, the pulmonary vascular pressure decreases and the left atrial pressure exceeds that of the right. This forces the septum primum against the septum secundum, functionally closing the foramen ovale.
