Dr. Smita Mishra, Associate Director, Paediatric Cardiologist, Jaypee Hospital, Noida, will discuss about the intervention done in ventricular septic defect in this video. If the VSD is large, baby is not growing well and is of six months of age then one should intervene. If the VSD is moderate then can wait for 3-4 months more. If the VSD is very small and heart size is normal and lung pressures are also normal, then can wait for long and monitor the patient.
