Randomization was run in a one\u2010to\u2010one fashion between radiofrequency ablation by TCc or SFc. Aim of PVs ablation was documentation of electrical isolation with exit\/entrance block recorded on a circular catheter. Among the 106 enrolled patients, 52 (49.0%) were randomized to TCc and 54 (51.0%) to SFc. Total volume of infused saline solution during the procedure was lower in the SFc than in TCc group (752.7 \u00b1 268.6 mL vs 1,165.9 \u00b1 436.2 mL, P &lt; 0.0001). Number of identified and isolated PVs was similar in the 2 groups. Number of PVs remaining isolated 30 minutes after ablation was higher in the SFc than in TCc group (95.2% vs 90.5%, P &lt; 0.03), mainly driven by acute ablation result in the left PVs (96.1% vs 89.7%, P &lt; 0.04). Complications were seldom and observed only in the TCc group (0% vs 3.84%, P &lt; 0.03). At 6\u2010month follow\u2010up SFc patients reported a trend toward less AF recurrences compared to those in the TCc group (22.9% vs 27.0%, P = 0.69).<\/jats:p><jats:p><jats:italic>Conclusion:<\/jats:italic> PV isolation by SFc lowered the rate of left PV early reconnections and reduced the volume of infused saline solution while maintaining the safety profile of AF ablation. <jats:italic>(J Cardiovasc Electrophysiol, Vol. 24, pp. 269\u2010273, March 2013)<\/jats:italic><\/jats:p>","DOI":"10.1111\/jce.12031","type":"journal-article","created":{"date-parts":[[2012,10,10]],"date-time":"2012-10-10T10:26:44Z","timestamp":1349864804000},"page":"269-273","source":"Crossref","is-referenced-by-count":30,"title":["Comparison of ThermoCool\u00ae Surround Flow Catheter Versus ThermoCool\u00ae Catheter in Achieving Persistent Electrical Isolation of Pulmonary Veins: A Pilot Study"],"prefix":"10.1111","volume":"24","author":[{"given":"EMANUELE","family":"BERTAGLIA","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GAETANO","family":"FASSINI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MATTEO","family":"ANSELMINO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GIUSEPPE","family":"STABILE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GIUSEPPE","family":"GRANDINETTI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ANTONIO DE","family":"SIMONE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LEONARDO","family":"CAL\u00d2","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CLAUDIO","family":"PANDOZI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CLAUDIO","family":"PRATOLA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FRANCO","family":"ZOPPO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CLAUDIO","family":"TONDO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ASSUNTA","family":"IULIANO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FIORENZO","family":"GAITA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,12,4]]},"reference":[{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10840-012-9672-7"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2007.00956.x"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2007.01071.x"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.102.20.2463"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000144459.37455.EE"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2005.00217.x"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.2459\/JCM.0b013e328013cd3c"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.108.772582"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2009.2029"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8167.2004.04052.x"},{"key":"e_1_2_8_12_2","doi-asserted-by":"crossref","first-page":"127","DOI":"10.1161\/01.CIR.0000151289.73085.36","article-title":"Recovered pulmonary vein conduction as a dominant factor for recurrent atrial tachyarrhythmias after complete circular isolation of the pulmonary veins.
