Device closure via minimally invasive left intercostal incision in children with perimembranous ventricular septal...

When treating perimembranous ventricular septal defect, median sternotomy leads to unsightly scar, right subaxillary thoracotomy requires cardiopulmonary bypass, and transcatheter device closure constrained by vascular condition. Using small left intercostal incision, we employed transthoracic device closure to get around these issues. During this study, right subaxillary thoracotomy was used for surgical repair in 117 patients (Surgical group), whereas small left intercostal incision was used for transthoracic device closure in 131 patients (Device group). Retrospective data collection and analysis were conducted. The success rate was comparable (117/117 vs. 130/131, P = 1.000). The device group experienced notably reduced operating time, mechanical ventilation duration, ICU stay, and postoperative hospital stay (All P < 0.001). Given that the device group's incision was much smaller than the surgical group's (1.1 ± 0.3 vs. 6.8 ± 1.6 cm, P < 0.001), blood transfusion or drainage tube was not needed. The device group observed a lower frequency of complications, with the exception of small residual shunt. It is feasible and safe to perform transthoracic device closure in children with perimembranous ventricular septal defects via small left intercostal incision. It can be a good minimally invasive substitute for surgical closure when utilized properly.
