Cardiac closure late

The newborn's skull has two unhealed areas called the anterior and posterior cardia. The anterior cardia is a diamond-shaped gap formed by the forehead and the parietal bone. About 1.5-2 cm in size at birth. After birth, the anterior condyle becomes larger with increasing head circumference. After 6 months, the ossification gradually begins to decrease, closing at about 1-1.5 years. The posterior condyle is a gap formed by two parietal bones and the occipital bone, which is triangular in shape. The posterior condyle is generally closed within 3 months after birth. If the anterior sacral closure time is more than 6 months and the posterior sacral closure time is more than 3 months after birth, it is considered that the cardia is closed late.
