Preductal coarctation results when an intracardiac anomaly during fetal life decreases blood flow through the left side of the heart, leading to hypoplastic development of the aorta. This is the type seen in approximately 5% of infants with Turner syndrome. [4] [5] Ductal coarctation: The narrowing occurs at the insertion of the ductus arteriosus.
Coarctation’s a fancy way of saying “narrowing”, so a coarctation of the aorta means a narrowing of the aorta. If we look at the heart, we’ve got the right and left atria, the right and left ventricles, the pulmonary artery leaving the right ventricle to the lungs, and the aorta leaving the left ventricle and going to to the body.
Patent ductus arteriosus (PDA) is a medical condition in which the ductus arteriosus fails to close after birth: this allows a portion of oxygenated blood from the left heart to flow back to the lungs from the aorta, which has a higher blood pressure, to the pulmonary artery, which has a lower blood pressure.
Persistent fetal circulation in neonates can be reversible or irreversible depending on the classified etiology listed above. If related to pulmonary disorders, the amount of lung damage dictates whether or not treatment is efficacious in reversing newborn lung insufficiency.
Other symptoms include a heart murmur which may range from almost imperceptible to very loud, difficulty in feeding, failure to gain weight, retarded growth and physical development, labored breathing (dyspnea) on exertion, clubbing of the fingers and toes, and polycythemia. [2]
Coarctation of the aorta which is, narrowing of a section of the aorta may also be observed. [1] Again this presents an obstruction to blood flow out from the left ventricle. [3] Since there is obstruction of flow into and out of the left ventricle, the prognosis depends on the degree of obstruction and its effect on blood flow.
An acyanotic heart defect, is a class of congenital heart defects.In these, blood is shunted (flows) from the left side of the heart to the right side of the heart, most often due to a structural defect (hole) in the interventricular septum. [1]
Cardiac defects, aortic coarctation and other aortic abnormalities. Eye anomalies. [2] Sometimes an "S" is added to PHACE making the acronym PHACES; with the "S" standing for "Sternal defects" and/or "Supraumbilical raphe." PHACE syndrome may affect infants with large plaque-type facial hemangiomas. [3]
