Figure captions

Figure 1. Chest CT scan axial slices demonstrating a perfusion defect (yellow arrows) in RSPV compatible with a thrombus protruding in left atrium.
Figure 2. Transesophageal echocardiography and fusion imaging reconstruction. A) Biplane midesophageal view: right pulmonary vein view (left panel) and derived orthogonal view (right panel) showing a large mass originating from the RSPV. B) Reconstruction of virtual transesophageal views from CT dataset. These images were obtained by tracing the esophagus (dotted green line) in the CT thorax scan dataset. Left and right panel reproduce the corresponding echocardiographic image above allowing to identify the hyperdense formation originating from the RSPV (yellow arrows) and protruding into the LA. C) Volume rendering and the angiographic fusion imaging reconstruction of the virtual transesophageal study.
Figure 3. Three-dimensional echocardiographic reconstruction of LA displayed from “en-face” perspective showing the origin of the thrombotic formation from RSPV close to interatrial septum.

Supplemental Material Figure III: Transesophageal three-dimensional reconstruction of LA from an “en-face” view (right panel) and the same image obtained with volume rendering reconstruction from the CT scan acquisition (left panel) with the thrombus (yellow arrows).
