A **large zipper mechanism** runs vertically along the midline of the heart, occupying the area where the interventricular septum would lie. The zipper pull and teeth are prominently displayed, symbolizing surgical opening or closure—an artistic representation commonly associated with patients who have undergone **open-heart surgery**, such as coronary artery bypass grafting (CABG), valve repair or replacement, or other median sternotomy procedures.

The tri-blend fabric creates a vintage, fitted look. And extreme durability makes this t-shirt withstand repeated washings and still remain super comfortable.
