Inferior left ventricle wall scar, short axis echocardiography view
Myocardial scarring is the accumulation of fibrous tissue resulting after some form of trauma to the cardiac tissue.[1][2] Fibrosis is the formation of excess tissue in replacement of necrotic or extensively damaged tissue. Fibrosis in the heart is often hard to detect because fibromas, scar tissue or small tumors formed in one cell line, are often formed.[3] Because they are so small, they can be hard to detect by methods such as magnetic resonance imaging.[1] A cell line is a path of fibrosis that follow only a line of cells.
