Surgical treatment of pediatric unroofed coronary sinus syndrome

Abstract

Objective To analyze the clinical features and surgical treatment of unroofed coronary sinus syndrome(UCSS) in children, and to provide evidence for the diagnosis and treatment of such diseases during the perio-perative period. Methods A retrospective analysis was conducted based on the clinical data of 13 patients with UCSS, who underwent surgical treatment at Beijing Children′s Hospital Affiliated to Capital Medical University from January 2011 to December 2017.All 13 patients were complicated with persistent left superior vena cava(PLSVC) and other cardiac malformations; 7 patients were diagnosed preoperatively and 6 patients were diagnosed intraoperatively.Eleven cases were diagnosed type Ⅰ and 2 cases were type Ⅳ according to Kirklin′s classification.In all of 13 cases, atrial septal reconstruction was performed to drain the left superior vena cava(LSVC) to the right atrium, and other cardiac malformations were corrected at the same time. Results One patient died in this group, and the other 12 patients had early recovery after operation.Postoperative-ventilator-assisted time was 5-246 h(median 29 h) and hospital stay time was 8-40 d(median 16 d). The remaining 12 cases were followed up from 6 months to 7 years and 2 months.No death or complications occurred.No residual shunt or residual obstruction was found. Conclusions In the case of congenital heart disease with PLSVC, UCSS should be alerted.Atrial septal reconstruction and drainage of LSVC into right atrium in children with UCSS can achieve satisfactory surgical results.
