Patent ductus arteriosus (PDA) with left-to-right shunting

Abstract

Patent ductus arteriosus (PDA) with left-to-right shunting is common congenital heart disease. The PDA with right-to-left shunting is rare. The main diagnostic methods are echocardiography, contrast echocardiography, electrocardiography and a complete blood count. When choosing a method for treating PDA direction shunting is accounted. With a left-to-right shunting the patient is recommended a surgery. With right-to-left shunting, the main goal of treatment is to reduce pulmonary arterial hypertension and preventive treatment of polycythemia. Therefore, drug therapy is prescribed with control of dynamics on treatment. Operative measure for this defect is associated with high risks. Our clinical case illustrates the clinical signs and diagnostic capabilities of PDA with Eisenmenger syndrome.
