Three‐Dimensional Mapping System. A focal source for atrial fibrillation (AF) may he found in the first few centimeters of the pulmonary veins. Radiofrequency (RF) ahiation may be directed at this source using activation mapping., but if the responsible atrial extrasystoles arc infrequent or difficult to map, elimination of the source may require complete electrical isolation of the vein with multiple RF lesions. A new three‐dimensional mapping system using a 64‐pole hasket catheter has been developed recently. We report the use of this system for abiation of focal AF in two patients. Mapping identified foci in the left and right superior pulmonary veins. Each focus was eliminated with a single RF ablation.
