Totally Endoscopic Robotic‐Assisted Cardiac Surgery in Children

摘要

Robotic surgery for intracardiac pathologies in children is relatively uncommon. This study presents our initial experience with robotic-assisted cardiac surgery in children. We also present the feasibility and safety of robotic surgery in children. From May 2013 to June 2018, 30 children underwent totally endoscopic robotic atrial septal defect closure (n = 22), right-sided (n = 5) or left-sided (n = 1) partial anomalous pulmonary venous connection repair, tricuspid valve annuloplasty (n = 4), and mitral valve replacement (n = 2, due to Barlow and rheumatic diseases). The mean age of the patients was 16.1 ± 1.1 years (range, 13-17) and the mean weight was 56.7 ± 0.1 kg (range, 42-77). Associated anomalies included left persistent superior vena cava (n = 2) and the absence of innominate vein (n = 1). All procedures were completed uneventfully. Operation time was 4.1 ± 0.6 h. No patient was converted to thoracotomy or sternotomy. Cardiopulmonary bypass and aortic clamping times were 90.6 ± 28.0 (range, 45-136) and 48.6 ± 24.9 (range, 15-94) min, respectively. The mean ventilation time was 3.7 ± 1.2 h and hospital stay time was 3.3 ± 0.7 days. No right phrenic nerve injury, hemorrhage, or blood transfusion were noted. One patient had postoperative pneumothorax, and 1 had supraventricular arrhythmia. Follow-up was a mean of 1.7 years (range, 1-52 months). Patients were healthy and no residual intracardiac defect was observed on echocardiography examinations. There was no operative or follow-up mortality. Robotically assisted cardiac surgery is a feasible and safe approach in selected pediatric patients. In the future, new generation robotic devices may offer an alternative surgical approach in cardiac surgery for younger children with lower body weight.
