Hydroninc baseboard over concrete slab

I've run the rough-in plumbing for first/second floor hydronic baseboard applications before. However, I am now running the rough-in plumbing for a basement apartment that has a concrete floor. Normally the supply and return pipes for the baseboard come up through the floor but with concrete I don't have this option. Is it possible to have them come out of the wall down low near the baseboard?

Sure, absolutely - it's done all the time, particularly in finished basements. You want to avoid putting pipes in exterior walls to avoid freezing. When the baseboards are below the main, purging air is more tricky. Need manual bleeders at high points and good to have power purge capability (isolation and drain valves at one end of the loop so that full system pressure can be applied for a one-way flush through the loop to the drain.

Maybe I misunderstood? I was visualizing the piping coming down from the floor above through the apartment walls.
