Introduction to Repeat Ablation

Cryoballoon ablation has become the preferred technique in many institutions as the first-line ablation approach because it leads to significantly fewer repeat ablations, direct-current cardioversions, all-cause rehospitalizations, and cardiovascular rehospitalizations during follow-up.

At repeat ablation, Rhythmia mapping confirmed clockwise perimitral flutter with slow propagation through the lateral mitral annular MA region (Fig.

Two patients recurred after MW and underwent repeat ablation without subsequent recurrence.

METHODS Data from 102 patients who underwent initial AF ablation and repeat ablation for recurrent atrial arrhythmia within 1-year follow-up were analyzed.

There was also a significant difference in favor of RFCA with respect to repeat ablations (3.

8% to 63%, which can be increased by subsequent/repeat ablation.

Repeat ablation at similar locations had a successful effect in 12 out of 16 (75.

Additionally, repeat ablation after primary treatment failure is a reasonable treatment approach with promising medium-term outcomes.

1, I2 = 9%), repeat ablation (RR: 0.

No relevant differences were observed with regard to repeat ablation (PVI 9% and PVIplus 11%).

In the BS group, 6 patients (12%) underwent repeat ablation compared with 77 patients (41%) in the non-BS group, (P < 0.

While studies have described reasons for initial ablation failure, less is known about outcomes of repeat ablation attempts.

CONCLUSIONS The VENUS-AF and MARS-AF will determine the safety and potential rhythm control benefit of VOM ethanol infusion when added to PVI in patients with persistent AF undergoing de novo or repeat ablation, respectively.

Radioiodine ablation (RAI) is the main alternative therapy, though surgery may have some advantages if done in a high-volume center; using higher weight-based doses of I-131 (250 μCI/g thyroid tissue) could increase proportion of patients achieving hypothyroidism and decrease repeat ablations.

98) were clinical factors predictive of one-year recurrence after the repeat ablation.

Patients with a LPLD approach had lower rates of need for a repeat ablation (21% vs 30%, p=0.

In this article, we summarize our approach to a repeat ablation for persistent atrial fibrillation when the pulmonary veins are already isolated.

7%), among those 7 patients underwent a successful repeat ablation procedure.

Six patients treated with CA had repeat ablation for residual tumor.

001) and the need for repeat ablation 5% vs 30% (p=0.

8% to 63%, which can be increased by subsequent/repeat ablation.

METHODS We performed a retrospective study of 558 patients who underwent de novo and repeat ablation for persistent AF.

Fifty-two patients (25 CBA and 27 cfRFA) underwent repeat ablation and no difference in durability of PVI was found.

Repeat ablations were performed successfully in those patients who developed recurrences.

EVIDENCE SYNTHESIS Four retrospective series assessed salvage treatments after FT failure evaluating cases of radical prostatectomy (RP) and repeat ablation (sample size from 12 to 22 patients).

Methods Repeat ablations after an EAS-guided PVI were analyzed.

After failure of catheter ablation and medical therapy he received 2 g omega-3 fatty acid supplementation while waiting on repeat ablation.

Recognizing early tumor recurrence is important, as small renal masses are often easily treated with repeat ablations.

Repeat ablation was performed in 6 of 7 patients.

Freedom from a repeat ablation procedure was 80.

The primary outcome was time to first documented recurrence of symptomatic or asymptomatic atrial tachyarrhythmia (AF, atrial flutter, or atrial tachycardia) between days 91 and 365 post ablation, or a repeat ablation procedure at any time.

Rate of repeat ablations was 20% in persistent and 32% in longstanding persistent AF (P = 0.

In addition, results of outcomes after repeat ablation in the elderly are lacking.

Follow-up (repeat ablation and vital status) was collected through 31 December 2016.

To test this hypothesis, we compared 12‐month readmission rates (all‐cause, cardiovascular [CV]‐related, and VT‐related), repeat ablation, and complications among patients with VT with structural heart disease undergoing ablation with versus without ICE.

Of the remaining, 13 patients underwent one or more repeat ablation procedures.

Repeat ablations were predominantly performed with RFC and resulted in similar acute success, duration of hospitalization, and antiarrhythmic drug prescription between the study cohorts.

Hereby, we discuss the hypothetical clinical scenario of a patient with AF relapse 6 months after PVI in whom all pulmonary veins are electrically silent at the time of repeat ablation.

Aims To define predictors of long-term outcome of a first repeat ablation solely consisting of re-isolation of reconnected pulmonary veins (PVs).

Repeat ablation strategy for atrial fibrillation (AF) recurrence after multiple ablation procedures is known to be challenging.

The Kaplan-Meier estimate of recurrence-free survival of restenosis after interventional PVS treatment was similar in patients without and with repeat ablation [75.

6 As authors stated, both the REDUCE AF7 (Pulmonary Vein Isolation to Reduce Future Risk of Atrial Fibrillation in Patients Undergoing Typical Flutter Ablation: Results from a Randomized Pilot Study) and the PREVENT-AF (Prophylactic pulmonary vein isolation during isthmus ablation for atrial flutter)8 trials reveled that prophylactic PVI reduced new-onset AF and burden in patients with lone AFl during clinical follow-up, with consequent reduction in hospitalizations and need to perform repeat ablation for AF.

However, electrophysiological differences in repeat ablation remain unclear.

Results There were 78 ablations including six repeat ablations.

ConclusionLeft posterior wall isolation with the CB-A is feasible and safe during repeat ablation procedures for recurrent PersAF.

Patients who underwent repeat ablations (27.

However, the usefulness of ablation of autonomic ganglia as an initial or repeat ablation strategy for paroxysmal, persistent, and long-standing persistent AF is not well established.
