Left atrioventricular plane displacement reflects the dysfunction in patients with heart failure. In previous studies, it has been reported that the displacement was decreased with progression of diastolic dysfunction [1, 2]. The purpose of our study is to use conventional cine magnetic resonance imaging to measure the displacement of the atrioventricular plane of the left ventricle in normal subjects and in patients with diastolic dysfunction.
To assess the change in position of the AVJ plane by noninvasive, conventional cine MRI to diagnose early diastolic dysfunction.
Results are shown in Figure 1: (b) the time courses of the 2-chamber AVJ displacement are shown for the representative Nl, NT and H during the cardiac cycle, (c) box plots of the 2-chamber maximum displacements (mean; -17.9,-14,-11.1; Nl, NT, H; respectively), and (d) box plots of the 2-chamber Thm (mean; 317.4, 552.1, 756.6; Nl, NT, H; respectively). The AVJ displacement is decreased in NT and H as compared to Nl.
Cine MRI measurement of the AVJ displacement provides a simple and potentially valuable noninvasive method to assess early left ventricular diastolic dysfunction. This method can be used on any conventional MRI system.
