ABSTRACT. Idiopathic ventricular arrhythmias from the papillary muscles have been infrequently observed. The unusual location of the arrhythmogenic site lends itself to a technically challenging procedure. This case describes the value of the CARTOSOUND platform in mapping and ablating ventricular ectopy of anterolateral papillary muscle origin.
