Abstract

Carbon monoxide is a nonirritant, odorless, colorless gas. Its effects are prominent in organs most sensitive to oxygen deprivation, such as the heart, brain, and kidney. Although less frequently, an association between thromboembolic events and carbon monoxide poisoning has been shown in the literatures. In this case, we report a case of atrial thrombus associated with carbon monoxide poisoning.

Figure

• 

  Fig. 1 Transesophageal echocardiography showed a mass (arrow) attached to right atrial appendage with to (A) and fro (B) motion through tricuspid valve.

• 

  Fig. 2 Delayed enhancement images (DE-MRI) showed an 8 mm sized thrombus (arrow) in the right atrium.

• 

  Fig. 3 Echocardiographic follow-up at sixth day of anticoagulation (B) showed disappearance of mass originally attached to right atrial wall (A, arrow).
