Persistent right venous valve with patent foramen ovale-related right-to-left atrial shunting caused transient, self-limiting oxygen desaturation (median minimum SpO2 87%) in healthy term neonates.
Observational (n=10)
No
Persistent right venous valve may facilitate right-to-left atrial shunting and cause transient oxygen desaturation in term neonates.
Background Persistent right venous valve (PRVV), a remnant of the fetal right valve of the sinus venosus, may facilitate right-to-left atrial shunting through the patent foramen ovale (PFO). Although PRVV has been reported to cause severe neonatal cyanosis requiring surgical intervention, its clinical significance in otherwise healthy term neonates remains poorly defined.
