Malignant Ventricular Arrhythmias After Surgery for Uncomplicated Congenital Atrial Septal Defect-Case Report
Abstract Background:Malignant ventricular arrhythmias (MVA) occurring subsequent to a repair of uncomplicated congenital heart disease is scarcely described in literature.Case presentation:One adult patient following congenital atrial septal defect (ASD) repair underwent immediate postoperative refractory MAV and ventricular fibrillation. The recurrent episodes of shocks cannot be suppressed by drugs. Emergent re-exploration was performed and repeated closure of ASD and DeVega's annuloplasty were completed. The patient had uneventful recovery and no occurrence of arrhythmia.Conclusion: Malignant ventricular arrhythmias are rare and should never be overemphasized even during the repair of uncomplicated congenital heart defect. Re-exploration should be taken into consideration when MVA occurred in the early stage postoperatively.
