Prediction of Cardiovascular Outcomes With Left Atrial Size

We sought to compare left atrial (LA) volume to LA area and diameter for the prediction of adverse cardiovascular outcomes. The incremental value of LA volume compared with LA area or diameter as a cardiovascular risk marker has not been evaluated prospectively for patients with sinus rhythm or atrial fibrillation (AF). Left atrial size was assessed with biplane LA volume, four-chamber LA area, and M-mode dimension for 423 patients (mean age 71...
