1. patent ductus arteriosus

   Patent Ductus Arteriosus (PDA) is a congenital (present from birth) heart defect where the ductus arteriosus, a blood vessel that allows blood to bypass the fetus's lungs before birth, fails to close after the baby is born. This leads to abnormal blood flow between the aorta and pulmonary artery, which can strain the heart and increase blood pressure in the lung arteries. If left untreated, PDA can lead to heart failure and other complications.

1. Patent ductus arteriosus

   Patent ductus arteriosus is a congenital disorder in the heart wherein a neonate's ductus arteriosus fails to close after birth. Early symptoms are uncommon, but in the first year of life include increased work of breathing and poor weight gain. With age, the PDA may lead to congestive heart failure if left uncorrected. The ductus arteriosus is a normal fetal blood vessel that closes soon after birth. In a patent ductus arteriosus the vessel does not close and remains "patent" resulting in irregular transmission of blood between two of the most important arteries close to the heart, the aorta and the pulmonary artery. PDA is common in neonates with persistent respiratory problems such as hypoxia, and has a high occurrence in premature children. In hypoxic newborns, too little oxygen reaches the lungs to produce sufficient levels of bradykinin and subsequent closing of the DA. Premature children are more likely to be hypoxic and thus have PDA because of their underdeveloped heart and lungs. A patent ductus arteriosus allows a portion of the oxygenated blood from the left heart to flow back to the lungs by flowing from the aorta to the pulmonary artery. If this shunt is substantial, the neonate becomes short of breath: the additional fluid returning to the lungs increases lung pressure to the point that the neonate has greater difficulty inflating the lungs. This uses more calories than normal and often interferes with feeding in infancy. This condition, as a constellation of findings, is called congestive heart failure.
