description: "A disruption of the structure of the sarcomeres of cardiomyocytes. The sarcomere is the repeating unit between two Z lines comprised largely of myosin and actin that mediates contractility, and normally sarcomeres are aligned with the long axis of cells, with the Z bands being in register throughout the length of the cardiac myocytes."
