The control group consisted of 33 patients with lone PAF. On DSCT, the recently developed PsAF group showed more extensive atrial anatomic remodeling than the PAF group as shown by \u223c40% higher spot biatrial volume, even though the mean duration of continuous AF was only 6 weeks. In contrast, the DSCT variables in the recently developed PsAF group and the short\u2010lasting PsAF group were comparable, despite the fact that the mean duration of continuous AF in the latter group was 8 months. Series of cross\u2010sectional areas of the ostial 1.5 cm of PV trunks were comparable in the PAF and PsAF groups in all but 3 ostial planes. A higher spot left atrial volume was the only independent factor associated with the progression of lone PAF to PsAF (OR: 1.06, 95% CI: 1.03\u20131.09, P&lt;0.0001) on logistic regression.<\/jats:p><jats:p><jats:italic>Conclusions:<\/jats:italic> Prominent anatomic remodeling of the atria, rather than the PVs, underlies the mechanism of recent progression of lone paroxysmal AF to the persistent variety. <jats:italic>(J Cardiovasc Electrophysiol, Vol. 23, pp. S29\u2010S35, November 2012)<\/jats:italic><\/jats:p>","DOI":"10.1111\/j.1540-8167.2012.02434.x","type":"journal-article","created":{"date-parts":[[2012,8,9]],"date-time":"2012-08-09T14:51:09Z","timestamp":1344523869000},"source":"Crossref","is-referenced-by-count":1,"title":["Morphologies of the Atria and Pulmonary Veins in Relation to Lone Atrial Fibrillation Progression: A Dual\u2010Source Computed Tomography Scan Study"],"prefix":"10.1111","volume":"23","author":[{"given":"XING\u2010PENG","family":"LIU","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XIA","family":"XU","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YING","family":"TIAN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"RI\u2010BO","family":"TANG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"RONG\u2010HUI","family":"YU","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"DE\u2010YONG","family":"LONG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"CAI\u2010HUA","family":"SANG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"CHEN\u2010XI","family":"JIANG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MAN","family":"NING","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JIAN\u2010ZENG","family":"DONG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"CHANG\u2010SHENG","family":"MA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,9,19]]},"reference":[{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2004.09.053"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehn139"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2009.11.040"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1253\/circj.68.568"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2008.01290.x"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2453070094"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2004.06.032"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-131-7-199910050-00002"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-007-0724-9"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2010.10.019"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehp063"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2008.01310.x"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2009.07.034"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehn324"},{"key":"e_1_2_8_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2008.08.071"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1540-8167.2012.02434.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1540-8167.2012.02434.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,12]],"date-time":"2023-09-12T13:16:50Z","timestamp":1694524610000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1540-8167.2012.02434.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,9,19]]},"references-count":15,"journal-issue":{"issue":"s1","published-print":{"date-parts":[[2012,11]]}},"alternative-id":["10.1111\/j.1540-8167.2012.02434.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1540-8167.2012.02434.x","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,9,19]]}}}
