Old scar returns high backscatter signals which can be misinterpreted as tissue perfusion, while in fact thay have an opposite (absence of viability) meaning. In this case mid-apical septum clearly shows subendocardial scar and epicardial absence of perfusion, leading to conclusion of complete absence of viability here.
