“…9 Dextrose has also been successfully applied via the great cardiac vein to ablate VT in a previously unsuccessful case, and the suggestion has been made that the use of low-or nonionic irrigants may be useful as an adjunct after failed ablation involving conventional NS. 10 Because RF catheter contact has a significant impact on lesion formation, cardiac and respiratory motions have important implications on procedural success. 11 The integration of detailed three-dimensional (3D) cardiac models obtained by computerized tomography or magnetic resonance imaging with 3D electroanatomic mapping and, recently, with fluoroscopic imaging enables precise anatomical catheter navigation under both nonfluoroscopic and fluoroscopic guidance.…”

A 27-year-old male presented to our institution with recurrent unifocal premature ventricular contraction/nonsustained ventricular tachycardia (VT) with associated cardiomyopathy. The patient had undergone three prior ablation procedures with continued arrhythmia. Mapping led to identification of the VT arising from the basal aspect of the left ventricular anterolateral papillary muscle. Conventional ablation techniques were unsuccessful. We incorporated adjunctive ablation techniques in this case that ultimately led to a successful outcome. The present discussion covers the roles of intracardiac echocardiography, induced apnea, and low-ionic irrigation.

“…The telescopic approach, involving stepwise catheter [29], guidewire advancement [30], and microcatheters in GCV/AIV and their branches [31], can be helpful if catheter positioning in the coronary veins is challenging. In cases of recurrence post-ablation within GCV/AIV, the use of low-or non-ionic coolant for irrigation is safe and may enhance radiofrequency power delivery both from the coronary vein and opposite endocardium [32][33][34].…”

Purpose of review During challenging scenarios of ventricular arrhythmia (VA) ablation, novel strategies to target the arrhythmogenic substrate are sometimes essential for clinical success. While catheter ablation (CA) can offer relatively high efficacy, it may not always lead to complete VA eradication in certain individuals. This article provides a brief overview of difficult substrate ablation strategies in patients with premature ventricular contractions (PVC) or ventricular tachycardia (VT) and explores methods to improve outcomes for cases that do not respond to typical ablation techniques. Recent findings Recent developments highlight the crucial role of advanced imaging and mapping techniques in the visualization, characterization, and localization of challenging ventricular substrates. Additionally, some novel and advanced ablation strategies may be useful when PVC/VT is refractory to conventional ablation treatment. Summary An expanding spectrum of techniques which can optimize the precision and effectiveness of catheter ablation procedures may improve PVC/VT ablation outcomes. Novel ablation therapies such as alcohol ablation, optimization of dispersive patch positions, or bipolar ablation, can overcome obstacles associated with the challenging anatomy of arrhythmia.
