Let’s review D-TGV!
💜 WHAT IS D-TGV? D-TGV is a congenital cardiac defect in which the location of the aorta and pulmonary arteries is switched. Instead of arising from the left ventricle, the aorta arises from the right ventricle. And instead of arising from the right ventricle, the pulmonary artery arises from the left ventricle.
✨WHY IS THIS A PROBLEM? Parallel circulations exist! Mixing of oxygenated and deoxygenated blood via ductus arteriosus or ventricular septal defect is essential for survival.
💜 HOW DOES PGE1 HELP PATIENTS WITH D-TGV? PGE1 helps maintain patency of the ductus arteriosus by relaxing its smooth muscle. This allows mixing of blood to occur until the patient can undergo surgery for stabilization and repair.
