The ideal index to predict the site of origin of outflow tract ventricular arrhythmias. Are we there yet?

An editorial focuses on advancements in predicting the site of origin for outflow tract ventricular arrhythmias (OT-VAs), crucial for successful catheter ablation procedures. It highlights the challenges posed by the anatomical complexity of OT-VAs, which can arise from various structures within the heart's outflow tracts, such as the right ventricular outflow tract (RVOT) and left ventricular outflow tract (LVOT).
