Although complete linear reablation is usually performed, we evaluated a simplified electrophysiological strategy selectively targeting recovered conducting isthmus tissue.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Methods and Results<\/jats:italic>\n            Twenty-one patients (18 men and 3 women, age, 54\u00b110 years) with a recurrence of typical atrial flutter 6\u00b17 months after an apparently successful catheter ablation in the IVC-TA isthmus prospectively underwent electrophysiologically targeted reablation during flutter. Sites with narrow electrograms or fractionated electrograms interposed between adjacent sites with double potentials considered to represent gaps were ablated without movement of the catheter. Mapping showed that 18 of 21 patients had a single gap. Successful ablation required a single application in 14 patients and, in the group as a whole, a median of one application (mean, 2\u00b12; range, 1 to 11) with resultant bidirectional block in 13 of 16. A single narrow electrogram (duration, 48\u00b16 ms; amplitude, 0.1\u00b10.05 mV) was noted at the successful site in 11, whereas a fractionated electrogram (97\u00b132 ms, 0.05\u00b10.04 mV,\n            <jats:italic>P<\/jats:italic>\n            &lt;.05) was noted in 9. There were four additional recurrences during a follow-up at 7\u00b15 months; three were similarly ablated with a median of one pulse.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            Transmural ablation lesions in the isthmus can be recognized during flutter by double potentials separated by an isoelectric interval. Postablation recurrent flutter is usually due to a single discrete recovered gap; this is represented by a single or a fractionated potential spanning the isoelectric interval of adjacent double potentials, which can be selectively targeted to minimize repeat ablation.\n          <\/jats:p>","DOI":"10.1161\/01.cir.96.8.2505","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:41:02Z","timestamp":1339461662000},"page":"2505-2508","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":72,"title":["Simplified Electrophysiologically Directed Catheter Ablation of Recurrent Common Atrial Flutter"],"prefix":"10.1161","volume":"96","author":[{"given":"Dipen C.","family":"Shah","sequence":"first","affiliation":[{"name":"From Service de Rhythmologie, Ho\u0302pital Cardiologique du Haut-Le\u0301ve\u0302que, Bordeaux-Pessac, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel","family":"Hai\u0308ssaguerre","sequence":"additional","affiliation":[{"name":"From Service de Rhythmologie, Ho\u0302pital Cardiologique du Haut-Le\u0301ve\u0302que, Bordeaux-Pessac, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Jai\u0308s","sequence":"additional","affiliation":[{"name":"From Service de Rhythmologie, Ho\u0302pital Cardiologique du Haut-Le\u0301ve\u0302que, Bordeaux-Pessac, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruno","family":"Fischer","sequence":"additional","affiliation":[{"name":"From Service de Rhythmologie, Ho\u0302pital Cardiologique du Haut-Le\u0301ve\u0302que, Bordeaux-Pessac, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Takahashi","sequence":"additional","affiliation":[{"name":"From Service de Rhythmologie, Ho\u0302pital Cardiologique du Haut-Le\u0301ve\u0302que, Bordeaux-Pessac, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meleze","family":"Hocini","sequence":"additional","affiliation":[{"name":"From Service de Rhythmologie, Ho\u0302pital Cardiologique du Haut-Le\u0301ve\u0302que, Bordeaux-Pessac, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques","family":"Clementy","sequence":"additional","affiliation":[{"name":"From Service de Rhythmologie, Ho\u0302pital Cardiologique du Haut-Le\u0301ve\u0302que, Bordeaux-Pessac, France."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_1_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(93)91014-9"},{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.86.4.1394929"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.94.12.3204"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(96)00345-2"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(95)00029-4"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.93.2.284"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.92.6.1389"},{"key":"e_1_3_1_8_2","first-page":"648","volume":"19","year":"1996","unstructured":"Fischer B, Ja\u00efs P, Cauchemez B, Shah DC, Gencel L, Garrigue S, Cl\u00e9menty J, Ha\u00efssaguerre M.
