High-density mapping of the papillary muscles in the left ventricle using a spiral catheter may be feasible. We identified the PVC foci away from the left ventricular shell. This consolidates the assumption for the origin of these ectopic beats at the junction between the chordae tendineae and the papillary muscles.
