The new technique described here has a potential to reduce or eliminate bronchial compression by pulmonary artery. Translocation of pulmonary artery anterior to the aorta takes the dilated pulmonary artery away from the trachea and bronchial tree. This approach was found to be technically feasible and can be useful especially in symptomatic newborns and infants.
Elective primary repair of tetralogy of Fallot in asymptomatic patients is delayed beyond 3 months of age. In symptomatic patients, primary repair of tetralogy of Fallot is performed irrespective of age, weight and preoperative state. This approach is safe, and provides an excellent midterm outcome with acceptable morbidity and rates of reintervention. The long-term benefits of this approach must be established by careful follow-up, with particular emphasis on arrhythmias, right ventricular function, and exercise performance.
The use of PTFE leaflet extensions is an effective technique for aortic valve reconstruction in congenital valvular disease. Long-term follow-up is necessary to assess the durability of this type of repair.
Single ventricle patients display several immunological abnormalities. Beyond the neonatal age, an immune pattern includes CD3, CD4, CD8 lymphopenia, and CD16 and CD19 lymphocytosis. B-cell lymphocytosis compensates T-cell lymphopenia, producing normal total lymphocyte counts in patients early after Fontan surgery. Low preoperative total lymphocyte counts may be associated with longer postoperative intensive care unit stay in patients with bidirectional Glenn and Fontan procedure and leukopenia with pleural effusions in Fontan patients.
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.
