Upside down Y scar on lower chest?

BaileyisDarcy
I'm curious what medical procedure would cause this kind of scar?

I'll admit im sticky beaking, i saw this scar on someone who posted to this site i frequent, the long end went up between her breasts, and the "prongs" of the Y, formed like a roof over her belly.

does anyone know what kind of procedure would cause this? It's such an interesting scar.

the prongs are above the belly but below the rib cage

its not heart surgery or rib removal. Its the wrong shaped scar in the wrong place for those. Completely healed and sunken into the skin rather than raised.
