RF ablation of idiopathic left ventricular outflow tract ventricular tachycardia (LOT-VT) may imply in significant risk of damaging the proximal left main if RF pulses are being delivered from the left sinus of Valsalva or from inside an epicardial coronary vein. This report describes a new approach to control LOT-VT by means of RF catheter ablation.

Background: The sympathetic autonomic nervous system plays a major role in arrhythmia development and maintenance. Historical preclinical studies describe preferential increases in cardiac sympathetic tone upon selective stimulation of the subclavian ansae (SA), a nerve cord encircling the subclavian artery.
Objectives: This study sought to define, for the first time, the functional anatomy and physiology of the SA in humans using a percutaneous approach.

Pulmonary vein isolation (PVI) represents the cornerstone of paroxysmal (PAF) and persistent atrial fibrillation (PsAF) ablation. Impedance values provide insights on tissue conductive properties. Consecutive patients undergoing PAF and PsAF ablation were prospectively enrolled.

Atrial fibrillation (AF) is the most common sustained arrhythmia, linked with a significantly heightened risk of stroke. While moderate exercise reduces AF risk, high-level endurance athletes paradoxically exhibit a higher incidence. However, their stroke risk remains uncertain due to their younger age, higher cardiovascular fitness, and lower rate of comorbidities.

Background: Colchicine is commonly used early after atrial fibrillation (AF) ablation to reduce inflammation and reduce AF recurrence, but there is limited long-term efficacy data.
Objective: To evaluate the effect of low dose colchicine use on long-term AF recurrence after AF ablation.
Methods: From 2013 to 2021, all AF ablations performed at a single tertiary care medical center were analyzed for colchicine use, clinical and procedural characteristics, and AF recurrence.
