Hello there. I can understand your concern. What i do not understand is how is it possible that a operation can be performed when there is no such defect. Who told you that the operation is wrongly performed. Also, when there was no septal defect, why did you give your consent for surgery? Please think before posting such questions and making such aquisitions. Due to your lack of knowledge you dont have to bring a bad name to our profession. No one will open the chest to repair the septal defect in a patient who doesnt have a defect. Think for yourself. Regards. Dr. Anil kumar jain.
