Introduction Tricuspid atresia with pulmonary atresia is a rare congenital heart defect, representing about 1% to 3% of all congenital heart diseases. Tricuspid atresia is subdivided into type I (normal position of the great arteries) and type II (transposition of the great arteries), with type 1A characterized by the presence of associated pulmonary atresia or stenosis. Pulmonary blood flow in these patients is dependent on the patency of the ductus arteriosus, making its maintenance essential in the neonatal period. The […]

Abstract Echocardiographic assessment of preterm infants, why do it? The incidence of premature births has been increasing worldwide and already affects about 10% of live births. Extremely preterm newborns (PTNB) are at increased risk of developing pulmonary immaturity, leading to pulmonary hypertension (PH), in addition to cardiovascular immaturity and patent ductus arteriosus (PDA).Hemodynamic monitoring of this population is challenging and differs from critically ill pediatric patients due to hemodynamic lability. Thus, minimal manipulation is essential to avoid complications. In this […]
