In this video, Dr. Radha Krishnan, Director, Pediatric Cardiologist at Fortis Escorts Heart Institute, New Delhi, will talk on surgical intervention of ventricular septal defect (VSD). He will discuss that VVSD is little different from ASD. If the VSD is large, which is defined by clinical symptoms and echocardiography, then all VSDs should be closed before six months of age. Dr. Radha Krishnan will also discuss as to why the closure in done immediately. The closure is done to repair the irreversible pulmonary hypertension. If it is a moderate size ventricular defect then one can wait up to 1-2 years of age and the baby is growing well. If the defect doesn’t close by itself then closure of the VSD is advised. He will further talk on the follow-ups regarding VSD.
