Total thoracoscopic repair of ventricular septal defect: A single‐center experience

OBJECTIVES: To explore the safety and efficacy of total thoracoscopic repair of ventricular septal defects (VSD). We compared clinical outcomes of VSD via a total thoracoscopic approach with those of mini‐sternotomy. METHODS: We retrospectively reviewed clinical data from patients with VSD from 2012 to January 2019. According to the surgical pattern, they were divided into two groups: the total thoracoscopic surgery group (36 patients, 27 females, aged 29 ± 9.52 years), and a mini‐sternotomy group (31 patients, 12 females, aged 28 ± 8.67 years). RESULTS: There were no deaths in either group. In the thoracoscopic group, cardiopulmonary bypass (CPB) time and aortic cross‐clamping (ACC) time were significantly longer than those of the mini‐sternotomy group (CPB time: 112 ± 23.16 min vs. 78 ± 37.90 min, respectively, p < .001; ACC time: 65 ± 19.94 min vs. 50 ± 24.90 min, respectively, p < .001). postoperative hospital stay time (5.11 ± 2.48 days vs. 5.90 ± 6.27 days, p = .488) and chest drainage (139.86 ± 111.71 ml vs. 196.13 ± 147.34 ml, p = .081) tended to be lower in the thoracoscopy group, although there was no significant difference. No residual shunt or tricuspid regurgitation was found at follow‐up. CONCLUSIONS: Total thoracoscopic repair is safe and effective in patients with VSD, with or without tricuspid regurgitation.
