Abstract

Background: Subclinical atrial stunning (AS) (left atrial dysfunction) may increase vulnerability to oxidative and inflammatory stressors, thus increasing the likelihood of postoperative supraventricular arrhythmias, especially atrial fibrillation (AF). Evaluation of mitral annular velocities by tissue Doppler imaging (TDI) may be useful in seeking subclinical AS. This prospective study aimed to evaluate the relationship between atrial fibrillation after bypass surgery and presurgical determination of subclinical AS by assessing mitral annular velocities by TDI.
