Ablation of atrial fibrillation (AF) through electrical isolation of the pulmonary veins (PVs) is usually performed using circular multipolar catheters. We describe our initial experience with the PentaRay® catheter (Biosense Webster, Inc.), which has five highly flexible branches and a total of 20 poles (Figure 1[1]). This was used for ablation of persistent AF in a 36-year-old female patient, in conjunction with the CARTO® navigation system (Biosense Webster, Inc.), to create a three-dimensional reconstruction of the left atrium (volume 142 ml) and the PVs, which was then integrated with images obtained by computed tomography angiography (Figure 2[2]). The PentaRay® catheter enabled rapid acquisition of a large number of points to obtain a voltage map with high signal resolution. The five-branched design, with highly flexible arms, fits easily inside the P...
