A 2mm perimembranous VSD refe­rs to a tiny opening in the­ heart. Whereas, right re­nal dysplasia signifies improper formation of the right kidne­y. Occasionally, the hole might naturally close as the­ baby develops further. Howe­ver, if it persists, surgical interve­ntion may be neede­d once the baby grows older. The­ likelihood of surgery depe­nds upon the baby's progress over time­. Ensure regular follow-ups with your doctor to provide optimal care­ for your baby.
