• Abstract

  Patients with cardiac septal defects can present hemodynamic changes in the small circulation, characterized by changes in flow and pressure, accompanied by structural adaptations in the pulmonary vascular tree ranging from pulmonary arterial smooth muscle cell hypertrophy to severe occlusive lesions. This condition may lead to disorders during the treatment of pediatric patients, particu…

• Abstract

  Severe cardiopulmonary hemodynamic disturbances may complicate the postoperative course in young pediatric patients undergoing surgery for repair of congenital cardiac septal defects, even after successful operation. Initially, it was considered that such disturbances were essentially the result of pulmonary vasoreactive response (vasoconstriction) associated with a number of perioperativ…

• Abstract

  Atrial septal defect is a congenital cardiac septal defect associated with an important increase in pulmonary blood flow with relatively mild increase in pulmonary artery pressure in the majority of young patients. There has been scarce literature on how this condition affects biochemical parameters of cardiac and endothelial dysfunction. Understanding these mechanisms is relevant, since …
