ABDALA, Diego et al. Cirugía cardíaca correctiva con circulación extracorpórea en lactantes de bajo peso e hiperflujo pulmonar. Arch. Pediatr. Urug. [online]. 2007, vol.78, n.2, pp.115-121. ISSN 1688-1249.

Summary Introduction: after unsuccessful medical treatment, infants with congenital heart disease (large left to right shunt, low weight and pulmonary infections) had palliative surgery (pulmonary artery banding). However, recent evidence suggest excellent results with early corrective surgery. Methods: we reviewed retrospectively the database of the Congenital Cardiac Department at the American Cardiac Center, during a 36-month period in order to identify  all infants who weighed less than 6 kg with congenital heart deffect and large left to right shunt, who underwent early surgical repair with cardiopulmonary bypass after unsuccessful medical management. We evaluated the morbidity and mortality before hospital discharge. Results: 22 infants were included; average age and weight were 151 days and 4.405 g respectively. At least one postoperative complication was found in 36,3%; a single death (4,5%) occured. Conclusions: continuous progress in perioperative management encouraged early corrective surgical repair with cardiopulmonary bypass in low weight infants with large left to right shunts decreasing operation risks and avoiding two stage surgeries.
