Total anomalous pulmonary venous connection, also known as total anomalous pulmonary venous return, is a rare cyanotic congenital heart defect in which the pulmonary veins drain into the right side of the heart instead of the left, as is usually seen. This can happen within the heart (intracardiac) where it drains into the coronary sinus or ...
Fetal abnormalities are conditions that affect a fetus or embryo, are able to be diagnosed prenatally, and may be fatal or cause disease after birth.They may include aneuploidies, structural abnormalities, or neoplasms.
The anomalous left coronary artery (LCA) usually arises from the pulmonary artery instead of the aortic sinus. In fetal life, the high pressure in the pulmonic artery and the fetal shunts enable oxygen-rich blood to flow in the LCA. By the time of birth, the pressure will decrease in the pulmonic artery and the child will have a postnatal ...
Aortopulmonary window (APW) is a faulty connection between the aorta and the main pulmonary artery that results in a significant left-to-right shunt. [2] The aortopulmonary window is the rarest of septal defects, accounting for 0.15-0.6% of all congenital heart malformations. [4]
Eisenmenger syndrome or Eisenmenger's syndrome is defined as the process in which a long-standing left-to-right cardiac shunt caused by a congenital heart defect (typically by a ventricular septal defect, atrial septal defect, or less commonly, patent ductus arteriosus) causes pulmonary hypertension [1] [2] and eventual reversal of the shunt into a cyanotic right-to-left shunt.
[citation needed] Diagnosis is usually made by investigation of a newborn baby who has developed jaundice during the first week of life. Testing. Coombs - after birth, the newborn will have a direct Coombs test run to confirm antibodies attached to the infant's red blood cells. This test is run from cord blood. [5]
CHB can be isolated, where the fetus does not suffer from any other problems, or it can be a result of other diseases either in the child or in the mother. [1] In most cases, the congenital heart block is associated with other diseases, [5] [4] [1] and therefore, the symptoms vary a lot between patients. However, low heart rate is usually the ...
Whether treated or not, the clinical course for the acute disease lasts about two to three days. During the first day, the child worsens and requires more support. During the second day, the baby may be remarkably stable on adequate support and resolution is noted during the third day, heralded by a prompt diuresis. Despite huge advances in ...
