Intra-abdominal Pressure (IAP) During PFA Treatment of A-fib/ A-Flutter

Intra-abdominal pressure (IAP) may play a role in patient outcomes during ablation procedures, as increased IAP could indicate potential adverse events. Such adverse events include aspiration of stomach contents, which can lead to respiratory issues post procedure and unplanned admission to the hospital post procedure. Potrero Medical has manufactured a foley based monitoring system that has been FDA cleared for the indication of measuring intra-abdominal pressure. The Accuryn monitor allows for continuous, real-time measurement of IAP and urine output, providing data that may enhance procedural safety and provide insights into any physiological responses unique to Pulsed Field Ablation (PFA). This study aims to compare PFA in terms of safety, efficacy, and IAP changes based on type of anesthesia received.
