Case report: Recovery of long-term delayed complete atrioventricular block after minimally invasive transthoracic closure of ventricular septal defect

Introduction Long-term delayed complete atrioventricular block (CAVB) is a serious complication of ventricular septal defect (VSD) closure treatment. Thus, cardiac surgeons have made significant efforts to explore its causes and reduce incidence. In recent years, minimally invasive transthoracic (MITC) VSD has been used widely successfully in China as it easy repeat, ensures individualized closure, can be debugged repeatedly. Theoretically, the possibility recurrence CAVB lower than that with transcatheter closure. Although incidence after MITC inevitable, long-term rarely reported. Case description Herein, we report case occurred 2 years 5 months performing perimembranous VSD. The rhythm recovered occluder was removed surgically. Conclusion findings our emphasize since may occur long term VSD, safety should reassessed, indications for strictly followed, follow-up, including lifelong recommended patients postoperatively. addition, surgically restore normal heart rhythm.
