“…Among patients under GA, PVCs appear to be more prone to suppression during mapping with a roving catheter, leading to AM cessation in the majority of cases in the GA group. While AM is the most commonly used technique to map ventricular arrhythmias, PM-based ablation accounts as a viable alternative [ 8 – 10 , 19 ]. In our study, the mapping approach was important as patients undergoing an AM-based ablation approach had a higher AAS, but was outperformed by the anesthesia type in predicting AAS independently.…”

Background The influence of divergent anesthesia types during ablation of premature ventricular complexes (PVCs) is not known. While previously performed under general anesthesia (GA) at our institution, these procedures were exclusively performed under local anesthesia (LA) ± minimal sedation during the COVID-19 outbreak for logistic reasons. Methods One hundred and eight consecutive patients (82 GA versus 26 LA) undergoing PVC ablation at our center were evaluated. Intraprocedural PVC burden (over 3 min) pre-ablation was measured twice: (1) at the start (before GA induction) and (2) before catheter insertion (after GA induction). Upon cessation of ablation and after a waiting period of ≥ 15 min, acute ablation success (AAS) was defined as absence of PVCs until the end of the recording period. Results Intraprocedural PVC burden was not significantly different between LA versus GA group: (1) 17.8 ± 3% vs 12.7 ± 2%, P = 0.17 and (2) 10.0 ± 3% vs 7.4 ± 1%, P = 0.43, respectively. Activation mapping-based ablation was performed significantly more in the LA vs GA group (77% vs 26% of patients, P < 0.001, respectively). AAS was significantly higher in LA vs GA group: 22/26 (85%) vs 41/82 (50%), respectively, P < 0.01. After multivariable analysis, LA was the only independent predictor for AAS (OR 13, 95% CI 1.57–107.4, P = 0.017). Conclusion Ablation of PVC under LA presented significantly higher AAS rate compared to GA. The procedure under GA might be complicated by PVC inhibition (after catheter insertion/during mapping) and PVC disinhibition post-extubation. Graphical Abstract

“…The quality of electroanatomic mapping (EAM) has become more and more refined over the past decade, as it is nowadays an integral part of the armamentarium for ablation of ventricular tachycardia (VT) and premature ventricular contraction (PVCs). 1 With the increase in the number of ablation procedures and the benefits of EAM, the treatment of complex ventricular arrhythmias has become more frequent. Notwithstanding the increased quality of EAM, limitations still arise when procedures are carried out in close proximity to the coronary vasculature.…”

Aims The goal of this case series was to evaluate the feasibility, safety, and advantages of a wire-based approach for the live visualization of coronary arteries (CAs) in an electroanatomic mapping (EAM) system and to assess its diagnostic information. Methods and results For this single-centre case series, we included procedures in which close proximity of a possible ablation site to any epicardial vessel was suspected. An uncoated-tip guidewire was introduced into the relevant CAs after exclusion of critical CA stenosis by coronary angiography. By connecting this wire to the EAM system using a clip and pin connection, mapping and live visualization of the wire tip is possible, as well as the assessment of the local electrograms within the respective CAs. Procedural wire insertion and intracoronary mapping was performed by EP specialists and was assisted to judge the relevance of CA disease by an interventional cardiologist. A total of nine procedures in nine patients were included in this case series, four ventricular tachycardia ablation procedures and five procedures for the ablation of premature ventricular contractions. The left CAs were mapped in eight cases and the right CA was mapped in one case. In two cases, epicardial mapping was combined with visualization of the right or left CAs. There were no complications attributed to coronary wiring and mapping in this case. Conclusion We demonstrated the feasibility and safety of CA visualization and integration in an EAM. The live visualization of the CAs added valuable information without the need for preprocedural planning or the purchase of separate software. Electroanatomic visualization was achieved intraprocedurally in a safe and straightforward manner, adding critical diagnostic information without excessive costs or risks.
