Currently available invasive and noninvasive techniques for the determination of left ventricular end-diastolic and end-systolic volumes, ejection fraction, and cardiac output are more time-consuming and potentially less accurate in patients with atrial fibrillation (AF) than in those with sinus rhythm. Although magnetic resonance imaging (MRI) can rapidly and accurately measure these variables in patients with sinus rhythm, its ability to do so in subjects with AF is not known. To determine if left ventricular volumes, ejection fraction, and cardiac output can be measured accurately in patients with AF using MRI, 26 subjects (13 women and 13 men, aged 15 to 76 years) in sinus rhythm (n = 13) or AF (n = 13) underwent MRI followed immediately by invasive measurements of these indexes. For those in AF, MRI measurements of left ventricular end-diastolic volume, end-systolic volume, stroke volume, ejection fraction, and cardiac output correlated well with catheterization measurements (r = 0.90, 0.90, 0.95, 0.85, and 0.90, respectively). In addition, the mean difference between MRI and catheterization measurements was similar in subjects with AF and in those with sinus rhythm. Compared with standard invasive measurements, MRI provides an accurate noninvasive determination of left ventricular volumes, ejection fraction, and cardiac output in patients with AF.
