Abstract:
Recently, a novel linear multielectrode mapping/ablation catheter was developed. We present a case in which mitral isthmus line ablation was undertaken with this catheter and showed repeated conduction recovery at the same site on the line. Mapping with this multielectrode catheter along the whole lesion allowed recording of abrupt conduction resumption.
