Bipolar radiofrequency maze procedure through a transseptal approach

Abstract

We report how to perform a complete open-heart ablation with bipolar radiofrequency through a transseptal incision. The connecting left atrial lines were performed by inserting one jaw of the clamp through a stab wound in the posterior left atrium, beneath the right inferior pulmonary vein. Twenty-five patients underwent concomitant ablation with the described technique in three different centers. All the left lines were easily performed. No ablation-related complication occurred. At 11 +/- 6 months, 80% of the patients were free from arrhythmias.
