Explainable machine learning for risk prediction of acute cardiac tamponade during atrial fibrillation ablation
This study develops an explainable machine learning (ML) model, specifically XGBoost, to predict acute cardiac tamponade during atrial fibrillation (AF) catheter ablation. By leveraging 1,481 patient records, the model identifies key predictors such as operator experience, D-dimer levels, total heparin dose, AF type, and left atrial diameter. Achieving an AUC of 0.972 (training) and 0.908 (validation), the model offers superior discrimination, calibration, and clinical utility compared to traditional methods. Its interpretability, through SHAP analysis, provides actionable insights for preoperative risk stratification and intraoperative management, enhancing patient safety and procedural precision, though external validation is needed.

Critical Predictors Identified for Tamponade Risk
Impact on Perioperative Management
The XGBoost model's ability to identify key risk factors like operator experience and D-dimer levels allows for personalized preoperative risk stratification. This insight enables clinicians to tailor intraoperative strategies, such as adjusting heparin doses or ensuring increased vigilance for high-risk patients, directly enhancing procedural safety. For instance, less experienced operators could be flagged for additional supervision or training modules, directly addressing a critical determinant of tamponade risk.
