In this report, we characterize pericaval reentry, a novel mechanism of isthmus\u2010dependent IART in congenital heart patients, and compare its electrophysiologic characteristics with periannular atrial flutter.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Methods and Results:<\/jats:italic>\n                    Electrophysiologic and electroanatomic mapping data and acute outcomes were reviewed in postoperative patients with congenital heart disease who underwent electrophysiologic study\/radiofrequency catheter ablation at The Children's Hospital, Boston between January 1999 and November 2000. The study included all congenital heart patients with IART and who had undergone (1) the Fontan procedure and (2) a biventricular surgical repair other than atrial switch procedures. Thirty\u2010seven IARTs were mapped in 22 Fontan patients. Twelve of 37 IARTs (33%) that revolved about the inferior vena cava (IVC) and involved the isthmus between the IVC and the tricuspid dimple\/right\u2010sided AV valve were identified in 12 patients (48%). Mean pericaval IART cycle length was\n                    <jats:styled-content>\n                      332\n                      <jats:bold>\u00b1<\/jats:bold>\n                      60 msec\n                    <\/jats:styled-content>\n                    (range 240\u2013410). An adjacent or surrounding area of scarring was observed in 10 of 12 IARTs. Slow zones (mean activation latency\n                    <jats:styled-content>\n                      39%\n                      <jats:bold>\u00b1<\/jats:bold>\n                      11%\n                    <\/jats:styled-content>\n                    IART cycle length) were detected in 8 of 12 circuits. The boundaries of the zone of slow conduction were scar\u2010low crista (6) and scar\u2010IVC (2).

In both forms of IART, the predominant direction of activation of the isthmus was lateral to septal; 83% in pericaval IART and 87% in periannular IART. Radiofrequency catheter ablation successfully terminated 11 of 11 pericaval and 13 of 14 periannular IARTs.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Conclusion:<\/jats:italic>\n                    Pericaval reentry is a novel and ablatable mechanism of IART in patients specific to the Fontan procedure. It is distinguished from periannular atrial reentry by its association with Fontan anatomy, longer cycle lengths, and occurrence of a prominent discrete zone(s) of slow conduction. Both pericaval and periannular reentry show a marked preference for utilization of the isthmus in a lateral\u2010to\u2010septal direction.\n                    <jats:italic>(J Cardiovasc Electrophysiol, Vol. 14, pp. 119\u2010125, February 2003)<\/jats:italic>\n                  <\/jats:p>","DOI":"10.1046\/j.1540-8167.2003.02391.x","type":"journal-article","created":{"date-parts":[[2010,8,16]],"date-time":"2010-08-16T05:41:52Z","timestamp":1281937312000},"page":"119-125","source":"Crossref","is-referenced-by-count":53,"title":["Pericaval and Periannular Intra\u2010atrial Reentrant Tachycardias in Patients with Congenital Heart Disease"],"prefix":"10.1111","volume":"14","author":[{"given":"RAVI","family":"MANDAPATI","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"EDWARD P.","family":"WALSH","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JOHN K.","family":"TRIEDMAN","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":"10.1016\/S0022-5223(97)70402-1"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199903183401103"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.91.8.2214"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8167.2001.00017.x"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(01)01192-5"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(96)00154-4"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.103.16.2060"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.101.25.2928"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.103.5.699"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.102.11.1283"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(00)01132-2"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.99.13.1700"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.103.25.3092"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(90)90314-F"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1997.tb00831.x"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.81.1.73"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-0736(98)90020-6"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.101.13.1568"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1997.tb01030.x"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1046\/j.1540-8167.2003.02391.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T04:35:08Z","timestamp":1694406908000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1046\/j.1540-8167.2003.02391.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,2]]},"references-count":19,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2003,2]]}},"alternative-id":["10.1046\/j.1540-8167.2003.02391.x"],"URL":"https:\/\/doi.org\/10.1046\/j.1540-8167.2003.02391.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]]}}}
