Stress-Radionuclide Ventriculography in the Evaluation of CABG Patients
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 . Thallium-201 scintigraphy offers the possibility of detecting additional reversible perfusion defects in the postoperative patient, but lacks a high sensitivity and specificity . Exercise radionuclide ventriculography (RNV) is another noninvasive tool which can provide quantitative and qualitative information about cardiac performance in the postoperative phase .
