Myocardial Perfusion Imaging After Coronary Artery Bypass Surgery Using Cardiovascular Magnetic Resonance.

The article discusses a study on whether myocardial blood flow (MBF) after coronary artery bypass grafting (CABG) is systematically underestimated by comparing resting MBF in grafted versus ungrafted segments after revascularization and segments before and after revascularization. The study population consisted of patients with left main coronary artery disease referred for elective CABG. It suggests that absolute quantification with cardiovascular magnetic resonance does not give rise to systematic underestimation of MFV in graft-subtended territories.
