Abstract:
Hemihypertrophy syndrome and cor triatriatum are extremely rare pathologies. Hemihypertrophy is defined as complete or partial overgrowth of one of the hemibodies. Cor triatriatum is a congenital heart disease characterized by a membrane which separates the left atrium into two chambers; if that membrane has a restrictive hole, it causes obstruction to blood passage from the pulmonary veins into the left ventricle causing hypertension and pulmonary edema. In this context, the patent ductus arteriosus can act as a means of decompression of the pulmonary circuit, because it allows the blood passage from the pulmonary artery to the aorta. We report a patient with Silver-Rusell syndrome (hemihypertrophy), cor triatriatum and ductus arteriosus with reverse flow. To our knowledge, this association of rare pathologies and this clinical presentation have not been described previously.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
