Despite the fact that the oxyhemoglobin dissociation curve is shifted leftward in patients who receive autologous umbilical cord blood, tissue oxygen delivery appears to be preserved in neonates who undergo open-heart surgery using autologous umbilical cord blood.
Background. Comorbid long segment congenital tracheal stenosis and congenital cardiovascular abnormalities in children pose significant challenges with regard to repairing these abnormalities simultaneously or in stages. The aim of this study was to explore whether this combination of abnormalities needs a staged approach for surgical repairs.Methods. All children who underwent both tracheal and cardiac surgical procedures at a tertiary hospital from 1995 to 2018 were analyzed retrospectively for mortality, ventilation days, postoperative intensive care unit days, mediastinitis, and unplanned reoperation by dividing them into simultaneous repairs (group 1), staged repairs within the same admission (group 2), and staged repairs during different admissions (group 3).Results. Of 110 patients included in the study (group 1, 74; group 2. 10; and group 3, 26 patients), there was no significant difference in mortality (P [ .85), median ventilation days
A neonate with antenatally diagnosed severe aortic valve stenosis, left ventricular outflow tract obstruction, left ventricular endocardial fibroelastosis, and severe mixed mitral valve disease was admitted to our center for balloon aortic valvuloplasty. On day 49, we performed a Ross-Konno procedure and mitral valve replacement on the baby, whose weight was 3.4 kg. Right ventricle-to-pulmonary artery continuity was restored with a handmade trileaflet Gore-Tex conduit. We used a handmade cylindrical prosthesis made from decellularized equine pericardium in the mitral position. We observed improvement in left ventricular function and good performance of aortic, pulmonary, and mitral prostheses at four months of follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
