An 87-year-old woman was admitted to our hospital because of acute renal failure, associated with heart failure and atrial fibrillation (AF). AF was very badly tolerated, and therefore, urgent electrical cardioversion (CV) was arranged. Considering the unknown AF duration, to rule out intra-atrial clots, a transesophageal echocardiogram (TOE) was performed before proceeding to CV. The TOE excluded the presence of clots in the left atrium and the left atrial appendage but showed a large thrombus straddling the fossa ovalis. The images, acquired with an off-axis mid-esophageal section at 70°, clearly demonstrated a large serpiginous thrombus (length 50 mm, maximal thickness 9 mm) wedging through a patent foramen ovale [[Figure 1] and Video 1]. Venous ultrasound of the lower limbs also revealed the presence of a left common femoral vein thrombosis. The patient was immediately treated with anticoagulant therapy and CV was delayed. Two weeks after, a TOE was repeated and showed the complete disappearance of the thrombotic formation. The echocardiographic finding of a leaking thrombus through a patent foramen ovale is very unusual, despite the high incidence of this anatomic variant in the healthy population. The diagnosis of paradoxical embolism is usually based on pure speculation, after having excluded other possible causes. In this case, we are able to show directly the event through a single iconic image. | Figure 1: Mid-esophageal section at 70° showing a large serpiginous thrombus wedging through the patent foramen ovale
