In addition, the clinical value of serial computed tomographic (CT) scanning of the PV ostia and the predictive value of energy requirements for radiofrequency ablation have yet to be established.<\/jats:p><jats:p> <jats:italic>Methods and Results:<\/jats:italic> We performed irrigated\u2010tip ablation in 37 patients with drug\u2010resistant PAF. Serial spiral CT scans were taken prospectively in 34 patients the day before the procedure, at prehospital discharge, and at 3\u2010 and 6\u2010month follow\u2010up. Using a clock model, energy requirements were analyzed for every segment of the PV circumference. One hundred fifteen PVs were targeted in 57 procedures. Compared to baseline, 7 (6.08%) of 115 PV showed minor (<jats:bold>&lt;<\/jats:bold>50%) PV stenosis. Two severe (<jats:bold>&gt;<\/jats:bold>90%) PV stenoses (1.73%) were detected with a mean follow\u2010up of <jats:styled-content>275 <jats:bold>\u00b1<\/jats:bold> 100 days<\/jats:styled-content>. Luminal narrowing occurred most frequently in the left inferior PV (6\/9 stenosed PV). Minor stenosed PVs showed their maximal luminal regression within the 3\u2010month follow\u2010up. Two of two PVs with narrowing <jats:bold>&gt;<\/jats:bold>50% at 3 months progressed to high\u2010grade stenosis. Analysis of delivered energy showed no significant correlation with the degree of stenosis. However, for the left inferior PV, more energy was applied in the superior segment of a stenotic PV (<jats:styled-content>6697 <jats:bold>\u00b1<\/jats:bold> 930 J<\/jats:styled-content> vs <jats:styled-content>3555 <jats:bold>\u00b1<\/jats:bold> 380 J, P <jats:bold>=<\/jats:bold> 0.005<\/jats:styled-content>).<\/jats:p><jats:p> <jats:italic>Conclusion:<\/jats:italic> Assessment of PV diameter by serial spiral CT scanning shows a low incidence of severe stenosis. The left inferior PV is at higher risk. Minor stenosed PV showed no progression after 3 months. Occurrence of stenosis tended to be related to the amount of energy delivered. <jats:italic>(J Cardiovasc Electrophysiol, Vol. 14, pp. 158\u2010164, February 2003)<\/jats:italic><\/jats:p>","DOI":"10.1046\/j.1540-8167.2003.02255.x","type":"journal-article","created":{"date-parts":[[2010,8,16]],"date-time":"2010-08-16T09:31:57Z","timestamp":1281951117000},"page":"158-164","source":"Crossref","is-referenced-by-count":46,"title":["Pulmonary Vein Stenosis by Ostial Irrigated\u2010Tip Ablation:"],"prefix":"10.1111","volume":"14","author":[{"given":"HELMUT","family":"P\u00dcRERFELLNER","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"RUDOLF","family":"CIHAL","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JOSEF","family":"AICHINGER","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MARTIN","family":"MARTINEK","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HANS JOACHIM","family":"NESSER","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2003,3,28]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.95.3.572"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199809033391003"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.102.20.2463"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1999.tb00654.x"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2007.00823.x"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1460-9592.2001.01261.x"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1998.tb00092.x"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1995.tb00386.x"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(00)00615-X"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.102.21.2565"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.101.7.772"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.103.14.1858"},{"key":"e_1_2_6_14_2","doi-asserted-by":"crossref","first-page":"1409","DOI":"10.1161\/01.CIR.101.12.1409","article-title":"Electrophysiological endpoint for catheter ablation of atrial fibrillation initiated from multiple pulmonary venous foci","volume":"101","author":"Haissaguerre M","year":"2000","journal-title":"Circulation"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.98.17.1769"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8167.2001.00900.x"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(02)01893-4"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8167.2001.00887.x"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2007.00981.x"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1046\/j.1540-8167.2003.02255.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T08:35:01Z","timestamp":1694421301000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1046\/j.1540-8167.2003.02255.x"}},"subtitle":["Incidence, Time Course, and Prediction"],"short-title":[],"issued":{"date-parts":[[2003,2]]},"references-count":18,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2003,2]]}},"alternative-id":["10.1046\/j.1540-8167.2003.02255.x"],"URL":"https:\/\/doi.org\/10.1046\/j.1540-8167.2003.02255.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":[[2003,2]]}}}
