RESUMO
Objective:To analyze the characteristics and surgical outcomes of Shone′s syndrome in children, and to explore the surgical treatment strategy and technical key.Methods:Retrospective study.Children with Shone′s syndrome treated in the Pediatric Heart Center, Beijing Anzhen Hospital, Capital Medical University from May 2013 to June 2019 were retrospectively analyzed for their baseline characteristics and surgical data.The data were compared by Student t-test. Results:A total of 22 children with Shone′s syndrome were recruited, involving 15 males (68.2%) and 7 females (31.8%). There were 6 cases (27.3%) of complete form of Shone′s syndrome and 16 cases (72.7%) of incomplete form.No deaths were reported.The postoperative mitral valve velocity [(149.7±38.2) cm/s vs.(234.9±34.0) cm/s, t=7.341, P<0.05], left ventricular outflow tract velocity [(202.0±105.0) cm/s vs.(328.6±120.3) cm/s, t=6.575, P<0.05] and aortic arch coarctation velocity [(186.1±60.9) cm/s vs.(347.9±100.8) cm/s, t=7.630, P<0.05]were significantly lower than those of preoperative levels.There were no complications occurred at 1-year follow-up, and 91.7% of the patients were followed up for 3 years, and 80.2% were followed up for 5 years without complications, 2 cases needed reoperation. Conclusions:Surgical treatment of Shone′s syndrome achieved satisfactory outcomes.Early diagnosis and early intervention are beneficial to children with Shone′s syndrome, although they need to be followed up and have the risk of reoperation in the long term.
