I'm really worried about my baby boy who has been diagnosed with a PM VSD hole that's 3.5 mm. Is this considered a big issue or not? I'm trying to understand how these measurements are categorizedis 3.5 mm small, moderate, large, or very large? Also, does this mean he'll need open heart surgery for sure, or could it close on its own as he grows? If surgery ends up being necessary, are there options other than open heart surgery that are less invasive? Would love some guidance on this.

Information provided is no adequate to answer,ideally if it is causing any cyanotic spells or pulmonary edema or PAH then Surgical correction is required which is not always open heart syurgery,if there are no such symptoms,repeat 2D echo after 6 months and check the status

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.
