The noninvasive assessment of myocardial perfomrance and graft function after coronary artery bypass grafting (CABG) is important for prescribing the patient’s postoperative exercise and rehabilitation program. The postoperative stress electro-cardiograph (ECG) and exercise performance are often used as noninvasive tests, but are limited due to their low sensitivity and specificity for detecting graft dysfunction [4]. Thallium-201 scintigraphy offers the possibility of detecting additional reversible perfusion defects in the postoperative patient, but lacks a high sensitivity and specificity [2]. Exercise radionuclide ventriculography (RNV) is another noninvasive tool which can provide quantitative and qualitative information about cardiac performance in the postoperative phase [5].
