Hi doctor! My child is more than 3 years old, when he was born, he had a ventricular septal defect. But I took the baby to the hospital to be examined, and it was diagnosed that it was okay. I took her to a cardiologist and the doctor said that she had a ventricular septal defect d=6.9mm, left ventricular dilatation, mild mitral regurgitation, mild pulmonary valve regurgitation, and the doctor indicated surgery.
