High\u2010density mapping of the dominant frequency (DF, 1200 Hz) and the mean degree of the complex fractionated electrograms (CFE mean interval over 6 seconds) was evaluated in 2 zones (zone 1: &lt; 5 mm, zone 2: 5\u201315 mm from the PVs) and the left atrial (LA) using a NavX system prior to the PV isolation. High\u2010DFs (&gt;8 Hz) and continuous CFEs (&lt;50 ms) were identified in 1.5 \u00b1 0.9 and 2.3 \u00b1 1.1 regions per patient, respectively. Most of the high\u2010DF regions (86%) and continuous CFE regions (77%) were located within 15 mm of the PV ostia. Of those, 75% of the high\u2010DF regions and 54% of the continuous CFE regions were related to arrhythmogenic PVs. There was a significant DF gradient from arrhythmogenic PV zone 1 to zone 2, while the mean CFE exhibited a significant gradient between arrhythmogenic PV zone 2 and the rest of the LA. Additionally, 69% of the procedural AF termination sites were at arrhythmogenic PV zone 2.<\/jats:p><jats:p> <jats:bold>\n            <jats:italic>Conclusion:<\/jats:italic>\n          <\/jats:bold> Evaluation of the atrial substrate properties may be useful for locating arrhythmogenic PVs during AF and defining the extent of the circumferential PV isolation. <jats:italic>(J Cardiovasc Electrophysiol, Vol. 22, pp. 405\u2010410)<\/jats:italic><\/jats:p>","DOI":"10.1111\/j.1540-8167.2010.01932.x","type":"journal-article","created":{"date-parts":[[2010,10,19]],"date-time":"2010-10-19T20:36:26Z","timestamp":1287520586000},"page":"405-410","source":"Crossref","is-referenced-by-count":12,"title":["Relationship Between Arrhythmogenic Pulmonary Veins and the Surrounding Atrial Substrate in Patients with Paroxysmal Atrial Fibrillation"],"prefix":"10.1111","volume":"22","author":[{"given":"KAZUYOSHI","family":"SUENARI","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YENN\u2010JIANG","family":"LIN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SHIH\u2010LIN","family":"CHANG","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LI\u2010WEI","family":"LO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YU\u2010FENG","family":"HU","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TA\u2010CHUAN","family":"TUAN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SHIH\u2010YU","family":"HUANG","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CHING\u2010TAI","family":"TAI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YUKIKO","family":"NAKANO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YASUKI","family":"KIHARA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HSUAN\u2010MING","family":"TSAO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TSU\u2010JUEY","family":"WU","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SHIH\u2010ANN","family":"CHEN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,10,19]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198204293061703"},{"key":"e_1_2_6_3_2","doi-asserted-by":"crossref","first-page":"3449","DOI":"10.1001\/jama.1985.03360240061035","article-title":"Characteristics and prognosis of lone atrial fibrillation.
