Postoperative interventricular septal haematoma following tetralogy of Fallot repair and perimembranous ventricular septal defect repair

Abstract

Interventricular septal haematoma is a rare postoperative complication in congenital heart surgery. We present one case of a 6-month-old after tetralogy of Fallot repair and 1 case of a 10-month-old after ventricular septal defect repair. Both were noted to have interventricular septal haematoma on intraoperative transoesophageal and postoperative echocardiogram. Although multiple previous reports, mainly in adults, have suggested aggressive intervention, both these cases were managed conservatively, highlighting the management and evolution of a rare postoperative complication in the paediatric population.
