Background: Ventricular septal defect (VSD) is the most common congenital heart disease (CHD) accounting for 20% to 30% of CHD.VSD repair is the most commonly performed pediatric cardiac operation. Recent reports have indicated a very low incidence of postoperative complications. One of these complications is residual VSD postoperatively. Residual VSD may result from insufficient intraoperative exposure or suture disruption with patch dehiscence and the type of suturing technique used. Constantine and Carl stated that elements of the surgical technique for VSD closure have remained subject to debate. Some surgeons prefer the running suture technique for VSD closure; others, the use of interrupted suture. These defects may have hemodynamic, financial and psychological impacts on the patients and their parents .They may need reoperation or device closure, drug therapy and antibiotic prophylaxis againstendocarditis. Patients and Methods: In the period between January 2016 and February 2018 , 50 patients with VSD underwent open heart surgery in Kasr Al-Ainy and other centers. Preoperative characteristics included sex, age at operation, bodyweight at operation, type of VSD , size of VSD , gradient across the VSD , Pulmonary pressure and associated anomalies if present. Intraoperative parameters included: Aortic cross clamp time, total bypass time, total operative time, technique for VSD repair and need for inotropic support
