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 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.
