RT Generic T1 Left atrial flutter after radiofrequency catheter ablation of focal atrial fibrillation A1 Pérez Villacastín Domínguez, Julián A1 Pérez Castellano, Nicasio A1 Moreno, Javier A1 González Davia, Rosa María AB We report an arrhythmic complication in two patients in whom a procedure directed at isolating one or two pulmonary veins had been performed. The complication was related to pulmonary vein disconnection scars after ablation. Both patients developed new clinical tachycardia (atypical atrial flutter) secondary to a reentrant phenomena in the vicinity of a previously ablated pulmonary vein.
