Contrast transesophageal echocardiographic detection of a pulmonary arteriovenous malformation draining into left lower pulmonary vein

Abstract

We report the identification of a pulmonary arteriovenous malformation draining into the left lower pulmonary vein by contrast two-dimensional transesophageal echocardiography in an adult with no evidence of hereditary hemorrhagic telangiectasia. To our knowledge, this has not been reported previously. This study also emphasizes the importance of transesophageal echocardiographic examination of the left lower pulmonary vein in the detection of a pulmonary arteriovenous malformation.
