Scintigraphy before and after the redo coronary artery bypass. a Exercise stress myocardial perfusion scintigraphy using technetium tetrofosmin reveals an extensive area of ischemia on the anterior left ventricular wall before redo coronary artery bypass grafting (white arrows). b Adenosine triphosphate stress myocardial perfusion scintigraphy using technetium tetrofosmin reveals blood flow recovery in the intraventricular septum after the redo coronary artery bypass grafting (red arrows)
