Beyond speed: why "skin-to-skin" time should not define quality in atrial fibrillation ablation

The growing celebration of "skin-to-skin" time in atrial fibrillation (AF) ablation reflects a concerning shift from physiology to optics. Procedural brevity, while operationally attractive, is increasingly highlighted as a visible marker of efficiency and may at times be interpreted as a marker of excellence despite lacking mechanistic or clinical validation as a quality surrogate. AF ablation is not defined by how rapidly lesions are delivered, but by how completely arrhythmogenic substrates are interrogated, challenged, and durably eliminated. Overemphasis on speed may unintentionally de-emphasize critical electrophysiological steps, including electrophysiologic testing, inducibility assessment, mapping, and rigorous post-ablation validation. In doing so, they promote a reductionist model of AF ablation-one that values efficiency over durability and appearance over outcome. Contemporary technologies, including pulsed field ablation, have undoubtedly improved procedural workflows, but they have not altered the biological determinants of success. Durable pulmonary vein isolation, identification of non-pulmonary vein triggers, and mechanistic completeness remain central. The field must therefore resist the conflation of speed with quality. In AF ablation, excellence is not measured in minutes, but in outcomes that endure.
