Over the past decades, percutaneous catheter ablation has become an important type of treatment for atrial fibrillation (AF). Pulmonary vein isolation is currently considered the cornerstone of management of paroxysmal and persistent AF. The duration of a catheter ablation procedure for radiofrequency isolation of pulmonary vein ostia using standard generator parameters largely depends on the surgeon, but usually lasts from 90 to 180 minutes. In an era of increasing numbers of patients with AF, the demand for ablation continues to grow. Against this background, the search for new techniques that can reduce the time spent in the left atrium and thereby reduce the risk of complications has also increased. One potential way is to use high-energy and short-term ablations (HECA).

This article describes the historical and evolutionary use of RF energy to perform ablation, discusses the technique of high energy and short duration ablation: “High power, short duration”.
