Revisitation of Double-Inlet Left Ventricle or Tricuspid Atresia With Transposed Great Arteries
Park and colleagues sought to identify risk factors that could predict the need for systemic outflow relief operations (SORO) in newborn patients with transposed great arteries and either double-inlet left ventricle or tricuspid atresia. The authors evaluated data from 20 patients with double-inlet left ventricle and 10 patients with tricuspid atresia who underwent single-ventricle palliation between 2000 and 2018. Approximately 67% of patients underwent SORO, and arch obstruction and smaller systemic outflow tract area index at end-systolic phase were both predictive of a subsequent need for an SORO.
