A Case of a Figure of Eight Atrial Tachycardia after a Pulmonary Vein Antrum Isolation of Atrial Fibrillation

A 66-year-old female, whom received a pulmonary vein (PV) isolation (PVAI) with linear ablation of the carina lines between the superior and inferior PVs of both the right and left PVs for atrial fibrillation (AF), was admitted to receive a radiofrequency catheter ablation (RFCA) of symptomatic drug...

description A 66-year-old female, whom received a pulmonary vein (PV) isolation (PVAI) with linear ablation of the carina lines between the superior and inferior PVs of both the right and left PVs for atrial fibrillation (AF), was admitted to receive a radiofrequency catheter ablation (RFCA) of symptomatic drug-refractory atrial tachycardia (AT). The EnSite(TM) analysis by the Advisor(TM) HD Grid catheter during the AT could easily detect that the carina between the right superior and inferior PVs exhibited a low voltage area (< 0.5 mV), in addition to the fact that the electrical activation turned around the right PVs in a figure 8, even though mapping was performed during AT. This AT was steadily terminated, after commencing the radiofrequency energy delivery to the carina of the right PVs.
