The CA procedure was guided by CARTO Merge atrial electroanatomic mapping. Sixteen patients (24.6%) had AF recurrence within the 6-month period after the CA. The recurrence was associated with a large RA volume [odds ratio, 1.04; 95% confidence interval (CI), 1.02 to 1.07,\n              <jats:italic>P<\/jats:italic>\n              &lt;0.0001], a large LA volume with 1.04 [95% CI, 1.01 to 1.06,\n              <jats:italic>P<\/jats:italic>\n              =0.002], and low LA mean voltage with 1.03 [95% CI, 1.01 to 1.05,\n              <jats:italic>P<\/jats:italic>\n              =0.002]. After adjustment for potential confounding variables, RA and LA volumes remained predictive of AF recurrence. Large atrial volumes (mL) (RA \u226587 or LA \u226599) predicted AF recurrence (sensitivity of RA volume: 81.3% in 13 of 16 patients with AF recurrence; specificity: 75.5% in 37 of 49 patients without AF recurrence; sensitivity of LA volume: 81.3% in 13 of 16 patients with AF recurrence; specificity: 69.4% in 34 of 49 patients without AF recurrence), and the combined estimate of both atrial volumes was incremental and additive prognostic power (sensitivity: 75% in 12 of 16 patients with AF recurrence; specificity: 93.9% in 46 of 49 patients without AF recurrence).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Both LA and RA remodeling are equally associated with post-CA AF recurrence.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circimaging.110.962761","type":"journal-article","created":{"date-parts":[[2011,7,22]],"date-time":"2011-07-22T02:28:07Z","timestamp":1311301687000},"page":"524-531","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":70,"title":["Association Between Left and Right Atrial Remodeling With Atrial Fibrillation Recurrence After Pulmonary Vein Catheter Ablation in Patients With Paroxysmal Atrial Fibrillation"],"prefix":"10.1161","volume":"4","author":[{"given":"Yasushi","family":"Akutsu","sequence":"first","affiliation":[{"name":"From the Division of Cardiology (Y.A., K.K., Y.
