approach for left-atrial size assessment using
cardiovascular magnetic resonance (CMR) imaging in
patients with atrial fibrillation and its value for
prediction of pulmonary vein isolation (PVI) treatment
success. MATERIALS AND METHODS: Eighty patients underwent
CMR imaging prior to PVI; the CMR examination included
standard cine sequences, a multislice cine sequence in
4-chamber orientation with full left-atrial coverage, and
a contrast-enhanced MR angiography of the left atrium.
Left-atrial size was determined as: diameter, area, volume
segmented from angiography, and diastolic/systolic volumes
from cine imaging (Simpson's rule). All measurements were
carried out by two independent observers and repeated by
one observer to assess inter- and intrareader variability.
Treatment success was defined as persisting sinus rhythm
after PVI (follow-up period 12.6 +/- 6.6 months). RESULTS:
All left-atrial measurements showed substantial
intrareader agreement. Interreader agreement was
substantial for diastolic/systolic left-atrial volumes
only. Calculated bias was found to be minimal
(0.1\%-4.9\%). Predictability of PVI treatment success was
best using cine volumetric measurements (cutoff value for
diastolic volume, 112 mL) yielding a sensitivity and
specificity of 80\% and 70\%, respectively. CONCLUSION:
Left-atrial volumetry based on cine imaging represented
the most reproducible approach to determine left-atrial
size. PVI success was predicted best using cine volumetry.",
