| Popis: | Background Data on the roof line (RL) and mitral isthmus line (MIL) reconnections after atrial fibrillation (AF) catheter-ablation (CA) are scarce. Objective We studied the RL and MIL completeness and localization of reconnection sites in consecutive patients after their first-ever AF-CA. Methods We prospectively included 41 consecutive AF patients who underwent predefined lesion sets of two circumferential lines (CLs) for ipsilateral pulmonary vein isolation (PVI) combined with a RL and lateral MIL. Three months after CA all patients underwent invasive follow-up procedure for line persistency evaluation, irrespective of clinical outcome. Results At the time of index ablation, PVI-CLs, RL and MIL was completed in 41 (100%), 39 (95%) and 34 (83%) of patients, respectively. At the 3-month follow-up procedure, reconnections of PVI-CLs, RL and MIL was found in 61% (25/41), 28% (11/39) and 24% (8/34) of patients, respectively. The 3-month reconnections were located commonly in the anterior and posterior PVI-CL segments, and rarely in the right third of RL and in the posterior part of MIL. The 3-month reconnections were rarely seen at the sites of acute reconnections during index procedure (6%, 20% and 25% of the PVI-CL segments, RL segments and MIL segments, respectively). Conclusions To our knowledge, this is the first study systematically investigating the reconnection of standardized LA linear lesions such as RL and MIL after RF-CA for AF in consecutive patients. The RL and MIL 3-month reconnection rates were relatively low (28% and 24%), with poor anatomical concordance between the sites with acute and 3-month reconnections.
