Impact of single vs. dual local anaesthetic regimen on the efficacy and safety of percutaneous stellate ganglion block for electrical storm: new insights from the STAR study

The combination of two local anaesthetics for PSGB is significantly associated with a greater likelihood of early and complete ventricular arrhythmia suppression in patients with electrical storm. Despite the need for randomized ad-hoc trials, the dual-LA regimen represents an optimization strategy for PSGB, offering enhanced efficacy without an increased risk of major complications.
