Significats de cavotricuspid isthmus en anglès

Methods: This study included 380 patients with typical AFL, who received linear ablation of the cavotricuspid isthmus.

The purpose of our study was to analyze long-term outcomes after catheter ablation of cavotricuspid isthmus-dependent AFL.

Conclusions: A single-catheter ablation approach to performing cavotricuspid isthmus line based on surface electrocardiogram PR interval measurement is feasible.

Conclusions: Irrigated-tip catheter ablation is safe and effective for achieving cavotricuspid isthmus block when conventional RF energy has failed.

Conclusions: Interindividual variations occur in the right atrial circuit of common atrial flutter, with constant activation through the cavotricuspid isthmus.

Conclusions: Linear ablation of the cavotricuspid isthmus is an effective therapy with low recurrence rate for patients with typical AFL.

We analysed the value of the delta PR interval in predicting bidirectional cavotricuspid isthmus block as confirmed by standard methods.

Hybrid therapy however, with ablation of the cavotricuspid isthmus is as suitable in elderly patients as in the young or middle-aged.

All patients had cavotricuspid isthmus ablation, and the cavotricuspid isthmus block was confirmed by differential pacing using two or three catheters.

Aim: To describe a new pacing technique using a single catheter to ablate and confirm cavotricuspid isthmus block with differential PR interval measurements.

This study investigated the long-term (up to 68 months) outcome of patients with typical AFL after catheter ablation of the cavotricuspid isthmus.

A delta PR interval cut-off of ≥70ms had 100% sensitivity and specificity to predict bidirectional cavotricuspid isthmus block.

Cavotricuspid isthmus block was achieved in all patients but one.
