My 1-month-old baby boy was diagnosed with a malaligned PM VSD hole measuring 3.5 mm. Is this considered large in medical terms? I'm trying to understand how VSD sizes are classified like small, moderate, large, or very large based on the mm measurement. Also, will my son definitely need open heart surgery, or is there a chance it could close on its own over time? If surgery is necessary, are there any less invasive options than open heart surgery?

A 3.5 mm VSD is usually small and may close on its own. Most small VSDs don‚Äôt need surgery. Serial echocardiograms are important to monitor.
