Description
M Gabarin and colleagues report a 2026 study linking the anatomy of the cavotricuspid isthmus to ablation workload in typical atrial flutter. Ultrasound imaging from inside the heart let operators grade that tissue bridge before burning it. In a retrospective cohort of two hundred consecutive patients treated without fluoroscopy, anatomy received a score from zero to six based on length, pouches, ridges, valve thickness, and shape.
Most patients scored in the mild range, and acute block of the isthmus was achieved in nearly every case. Each extra point on the score added roughly fifty seconds of ablation time and about four more energy applications. The score did not predict acute success, and its link to later flutter recurrence, seen in seven percent overall, was modest. Complications were rare, so the authors propose the score mainly for planning and operator guidance.
