CARDIAC tamponade during atrial fibrillation (AF) catheter ablation was accurately predicted using a machine learning model that achieved strong discrimination and clinical utility in a large Chinese cohort.
Cardiac tamponade, a life-threatening accumulation of fluid in the pericardial sac that compresses the heart, remains a rare but catastrophic complication of AF catheter ablation. Although AF ablation is widely performed to control symptomatic arrhythmia, identifying patients at highest risk of intraoperative complications has remained challenging.
In a retrospective study of 1,481 patients who underwent AF catheter ablation at a tertiary hospital in Nanjing, China, between October 2014–December 2024, researchers developed a predictive model for cardiac tamponade using machine learning techniques….
