Early Surgical Closure of the Ventricular Septal Defects; to Be Done or Not to Be Done? A Question to Be Answered

Ventricular septal defect (VSD) includes 40% of congenital heart diseases. Surgical closure of VSD is the most common procedure in pediatric cardiac surgery. Weight is the most restrictive factor for performing the surgery as it complicates the operation and post-operative care. The aim of this study was to determine the results of the surgery for the patients undergoing this procedure with the weight under 5 kilograms and to catch a good insight into performing surgery at lower age and weight. A retrospective study was conducted by operative and postoperative case note review of 54 patients from March 2014 to 2017. We assessed the outcomes of the early surgical closure of the ventricular septal defects. In our study, the weight was 4.4 + 0.61 kilograms and the age was 5.72 + 2.22 months. Post-surgical result by echocardiography showed reduced immediate pulmonary artery pressure in all patients, other post-surgical evaluations showed 1 (1.9%) mild, 1 (1.9%) moderate to severe pericardial effusion, 1 (1.9%) first degree AV Block, 2 (3.7%) right bundle branch block and 4 (7.4%) complete heart block leading to permanent pace maker implantation. Significant myocardial stunning (ejection fraction < 40%) was noted in 6 (11.11%). The patient mortality in the first 30 days was zero and there was no post-operative immediate endocarditis, seizure, bleeding or cardiac arrest. Observations can prove increased ability, knowledge and techniques of the surgeons operating VSDs. Based on the outcomes, earlier surgical VSD closure is recommended.
