isthmus

Incidence of new-onset atrial fibrillation after cavotricuspid isthmus ablation for atrial flutter.

Necessity for biatrial ablation to achieve birectional cavotricuspid isthmus conduction block in a patient following Senning operation.

Randomized study comparing combined pulmonary vein-left atrial junction disconnection and cavotricuspid isthmus ablation versus pulmonary vein-left atrial junction disconnection alone in patients presenting with typical atrial flutter and atrial fibrillation.

Necessity for biatrial ablation to achieve bidirectional cavotricuspid isthmus conduction block in a patient following Senning operation.

Acute effectiveness, defined as the proportion of patients achieving bidirectional block across the cavotricuspid isthmus, was 87.5% (140 of 160 patients), which met the goal of more than 80% acute effectiveness rate.
