Description
Masatsugu Nozoe led a team that diagnosed and treated a fast, circling atrial rhythm arising where the superior vena cava meets the right atrium. Their 2026 case involved a 72-year-old man whose atrial fibrillation had returned a decade after a cryoballoon procedure, and they worked with a dual-energy lattice-tip catheter that can both map and ablate.
High-density mapping pinpointed the narrow channel of tissue the rhythm needed to keep circling. Mapping while the heart was in its normal rhythm helped the team relate that channel to the site where the sinus node first fires. Pulsed-field energy could then be delivered while sparing the node itself. The treatment caused neither sinus node damage nor weakness of the phrenic nerve in this patient.
