Aortopulmonary (bothal) or atrial septal defect is a congenital heart defect characterized by a violation of the integrity of one of the two layers of this septum: either its partial disconnection, or the formation of the entire opening through which blood flows from the right ventricle to the lungs. In the first case, the defect of such a septum is called the Botallov duct. In the presence of an interventricular septum, the right atrium communicates with the right ventricle. This form is clinically the most significant and can lead to various consequences: hemodynamic disturbances, hypertension of the pulmonary circulation, thrombus formation in the lungs, pulmonary infections, cyanosis, shortness of breath, and general deterioration of the condition.
The most common congenital heart defect is patent ductus arteriosus (botallus) at the site of the transition of the arterial end of the aorta to the left side of the heart. First in newborns in an area corresponding to their position
