Structural heart disease was equally prevalent in both groups (39%) while history of previous ablations was more common in the study arm (54% vs 30%, P = 0.001). Most of the ablation cases were for atrial fibrillation (46%), followed by atrial tachycardia (28%), supraventricular tachycardia (12%), and ventricular tachycardia (14%). Median procedure duration was 128 (52\u2013147) minutes with the bidirectional, versus 143 (105\u2013200) minutes with the conventional catheter (P = 0.232), and median fluoroscopy time was 17 (10\u201334) minutes versus 23 (12\u201339) minutes, respectively (P = 0.988). There was a trend toward a lower procedure duration for the atrial tachycardia ablations, 89 (52\u2013147) minutes versus 130 (100\u2013210) minutes, P = 0.064. The procedure was successfully completed in 96% of the bidirectional versus 84% of the control cases (P = 0.151). A negative correlation was observed between the relative fluoroscopy duration and the case number (r = \u20130.312, P = 0.028), reflecting the learning curve for the bidirectional catheter.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The introduction of the bidirectional catheter resulted in no prolongation of procedure parameters and similar success rates, while there was a trend toward a lower procedure duration for atrial tachycardia ablations.<\/jats:p><\/jats:sec>","DOI":"10.1111\/pace.12113","type":"journal-article","created":{"date-parts":[[2013,2,25]],"date-time":"2013-02-25T17:16:02Z","timestamp":1361812562000},"page":"757-763","source":"Crossref","is-referenced-by-count":7,"title":["Use of Asymmetric Bidirectional Catheters with Different Curvature Radius for Catheter Ablation of Cardiac Arrhythmias"],"prefix":"10.1111","volume":"36","author":[{"given":"LILIAN","family":"MANTZIARI","sequence":"first","affiliation":[{"name":"Cardiology Department Royal Brompton and Harefield Foundation Trust  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"IRINA","family":"SUMAN\u2010HORDUNA","sequence":"additional","affiliation":[{"name":"Cardiology Department Royal Brompton and Harefield Foundation Trust  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MARKO","family":"GUJIC","sequence":"additional","affiliation":[{"name":"Cardiology Department Royal Brompton and Harefield Foundation Trust  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DAVID G.","family":"JONES","sequence":"additional","affiliation":[{"name":"Cardiology Department Royal Brompton and Harefield Foundation Trust  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TOM","family":"WONG","sequence":"additional","affiliation":[{"name":"Cardiology Department Royal Brompton and Harefield Foundation Trust  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"VIAS","family":"MARKIDES","sequence":"additional","affiliation":[{"name":"Cardiology Department Royal Brompton and Harefield Foundation Trust  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JOHN P.","family":"FORAN","sequence":"additional","affiliation":[{"name":"Cardiology Department Royal Brompton and Harefield Foundation Trust  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SABINE","family":"ERNST","sequence":"additional","affiliation":[{"name":"Cardiology Department Royal Brompton and Harefield Foundation Trust  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,2,25]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.108.824789"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2009.02.014"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2009.04.040"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2010.01829.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2010.01756.x"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2010.01730.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10840-008-9272-8"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eun225"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.110.957761"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eup069"},{"key":"e_1_2_7_12_1","unstructured":"EdwardsS ThompsonR inventors; Catheters with electrode tip having asymmetric left and right curve configurations.
