This is a single line, but it holds a whole emotional event. Someone or something "clutched" the speaker's heart, which suggests a sudden, tight grip, the kind of pain or overwhelming feeling that stops you in your tracks. Then the feeling "gushed out" through the eyes, which most naturally reads as tears: what was held inside the chest is forced out in a rush.
The poem doesn't say who "he" is or what he did, and that gap matters. He could be a lover, a loss, a memory, or even a personal presence like grief itself. Because we're given no explanation, the focus stays on the speaker's body and the force of the reaction rather than the cause.
The mood is raw, intense, and a little helpless. The verbs are physical and violent, so the speaker seems to have no control over what happens. Crying here isn't gentle or quiet. It's something done to them, sudden and overwhelming, and the brevity of the line makes it feel like a gasp.
