Heart Harvester

The Heart Harvester isn't a singular creature, it's actually the name of a condition, specifically a rare breed of parasites. Smaller than even blood cells, these 'crustaceans' infest the chambers of your heart. After munching steadily on red blood-cells, they work up their numbers (into the millions) enough to attack the meat of the heart itself. When this orchestrated feeding frenzy occurs, your heart is liquified and excreted into your bloodstream.

The demise of one who's contracted the Heart Harvesters is both horrific and painful.
