Anhydrous ethanol infusion of the vein of Marshall during atrial fibrillation ablation carries a risk of delayed pericarditis, highlighting the need for careful volume administration to prevent vessel damage.
May warrant limiting VOM ethanol volume plus delayed surveillance; leaves open whether this prevents rare late pericarditis.
In this case report, we will discuss a 74-year-old female who presented with a chief complaint of abdominal pain, bloating, anorexia, and nausea for four days which preceded after catheter ablation and anhydrous ethanol infusion vein of Marshall (VOM) one month prior. She was admitted and treated as a general patient in the general ward. After hospital admission, a pericardiocentesis was guided by B-scan ultrasonography, resulting in the extraction of 20ml of pericardial effusion, followed by catheterization for drainage. The key takeaway in this report is that anhydrous ethanol infusion VOM may not always be without risks. Hence, during the procedure, it is imperative to carefully administer the appropriate volume of anhydrous ethanol into the VOM to prevent vessel damage and associated complications.
