Total Anomalous Pulmonary Venous Return

A discussion on the diagnosis, symptoms and treatment of ‘total anomalous pulmonary venous return’ a congenital heart defect.

This paper discusses how physicians can screen for the cardiac defect ‘total anomalous pulmonary venous return’. It examines the research of treating the problem and it suggests managing the disease through teamwork with a pediatric cardiologist, a cardiac surgeon and neonatologist.
“Total anomalous pulmonary venous return is a congenital heart defect. Caused by the abnormal development of a fetus’s heart during the first eight weeks of pregnancy, the vessels that feed blood that has traveled back from the heart to the lungs are improperly connected. During the middle of this fetal development period, the tricuspid valve does not develop properly – ventricular development is influenced by blood flowing through it, and since no blood is able to pass through the tricuspid valve, the right ventricle remains small.In a normal heart, oxygen-poor, or blue, blood returns to the right atrium after it has circulated through the body, travels to the right ventricle and then is pumped through the pulmonary artery into the lungs where it is enriched with oxygen. That oxygen-rich, or red, blood returns to the left atrium from the lungs through four pulmonary veins. It then passes into the left ventricle and is then pumped back out for circulation throughout the body.”
