“…A tridimensional (3-D) mapping system was used in 416 cases (Biosense Webster CARTO system in 224 cases and Abbott-St. Jude Ensite NavX or Velocity in 149 cases, unknown in the remaining), while no 3-D mapping system was used in 531 patients. No data were reported regarding use of mapping system in one study (6 patients) [48]. Irrigated or non-irrigated 3.5 or 4 mm tip catheters were used for mapping and ablation ( Table 2).…”

Introduction: Catheter ablation has been evaluated as treatment for fascicular ventricular tachycardia (FVT) in several single-centre cohort studies, with variable results regarding efficacy and outcomes. Methods: A systematic search was performed on PubMed, EMBASE and Cochrane database (from inception to November 2017) that included studies on FVT catheter ablation. Results: Thirty-eight observational non-controlled case series comprising 953 patients with FVT undergoing catheter ablation were identified. Three studies were prospective and only 5 were multi-centre. Eight-hundred and eighty-four patients (94.2%) had left posterior FVT, 25 (3.4%) left anterior FVT and 30 (2.4%) other forms. In 331 patients (41%), ablation was performed in sinus rhythm (SR). The mean follow-up period was 41.4±10.7 months. Relapse of FVT occurred in 100 patients (10.7%). Among the 79 patients (8.3%) requiring a further procedure after the index ablation, 19 (2%) had further FVT relapses. Studies in which ablation was performed in FVT had similar success rate after multiple procedures compared to ablation in SR only (95.1%, CI95%92.2-97%, I2=0% versus 94.8%, CI95%87.6-97.9%, I 2 =0%, respectively). Success rate was numerically lower in paediatric-only series compared to nonpaediatric cases (90.0%, CI95%82.1-94.6%, I 2 =0% versus 94.3%, CI95%92.2-95.9%, I 2 =0%, respectively). Conclusion: Data derived from observational non-controlled case series, with lowmethodological quality, suggest that catheter ablation is a safe and effective treatment for FVT, with a 93.5% success rate after multiple procedures. Ablation during FVT represents the firstline and most commonly used approach; however, a strategy of mapping and ablation during SR displayed comparable procedural results to actively mapping patients in FVT and should therefore be considered in selected cases where FVT is not inducible.

“…in 14 ILVT patients, who likewise found a predilection for successful ablation sites in the posteroseptal region and near the posteromedial papillary muscle . However, there are clearly exceptions to this pattern where more anterior sites along the septum may be the successful target site, as seen in both our own series and reports from other centers …”
