My baby girl is 80 days old and has a 3.7mm PDA. What effect will this have on her? Should we wait for it to close naturally or consider surgery?

More Paediatric Cardiology Health Queries
View allI'm really worried about my newborn baby boy's health. His report mentions a small perimembranous VSD, mild pulmonary stenosis, and a small residual PDA. Can someone explain what these mean? Are these issues something he'll outgrow, or will they need ongoing treatment? I'm looking for more information on how serious these are and what the next steps should be. Would really appreciate some guidance.
Your newborn's report indicates three congenital heart conditions: a small perimembranous ventricular septal defect (VSD), mild pulmonary stenosis, and a small residual patent ductus arteriosus (PDA). A small VSD is a hole in the heart's septum that can sometimes close on its own but needs monitoring. Mild pulmonary stenosis is a narrowing near the pulmonary valve that restricts blood flow to the lungs and often requires regular follow-up. A small residual PDA is an open vessel that normally closes after birth; it may close on its own or require medical management. The treatment plan will depend on how these conditions affect your child's health, and regular follow-ups with a pediatric cardiologist are essential to monitor and manage them. Discuss these findings with your child's cardiologist to understand the prognosis and specific treatment options.

My 2-month-old preterm baby born at 35 weeks was diagnosed with a 6mm VSD, 3mm ASD, and moderate PDA, all left-to-right shunts. She weighs 3.5kg now and has no symptoms feeding well, gaining weight, and passing urine/stool normally. We've seen 23 pediatric cardiologists, and all recommend surgery but with different timelines some say immediately, others say before 6 months or until she's 1 year and 10kg. Since she's doing fine now, when would be the right time for surgery?
A detailed evaluation will help decide the best course of action.
