All patients underwent PE screening with ultrasound within 12\u2009h post\u2010procedure. Left atrial high\u2010density bipolar voltage mapping was performed before and after VOM\u2010EI to identify the VOM\u2010EI related low\u2010voltage area (LVA). The Boruta algorithm and logistic regression were employed to identify risk factors for PE. The model's performance was assessed using the area under the receiver operating characteristic curve (AUC). Acute post\u2010procedural PE was observed in 22 out of 87 patients (25.2%); no cases of cardiac tamponade occurred. The mean effusion depth was 4.59\u2009\u00b1\u20092.72\u2009mm. The Boruta algorithm ranked the importance of variables as follows: LVA, procedure time, and heart failure. Multiple logistic regression analysis identified LVA as an independent predictor for PE (OR: 1.15; 95% CI: 1.01\u20131.30;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.030) after adjusting for procedure time and heart failure.
