Morphology
The phrase uses a bodily-metaphor combining 'heart' (emotion) with location 'in one's mouth', which evokes a vivid physical sensation of sudden fear and is therefore partially inferable from the constituents. However, the precise idiomatic sense 'extremely anxious or fearful' is metaphorical and not fully predictable for a B1 learner without prior exposure, even though similar metaphors occur in other languages.
Etymology
Heart in one's mouth may come from the strong physical feeling of fear when it seems your heart jumps up toward your mouth or throat. That's why the phrase means 'feeling very anxious or scared'.
