This case highlights the utility of agitated saline studies during transesophageal echocardiography (TEE) for detection of pulmonary arteriovenous malformations (PAVM) as a viable alternative to contrast‐enhanced imaging studies. By carefully studying each pulmonary vein individually during saline contrast studies, TEE is able to demonstrate and localize PAVM. In addition, this report represents the first documentation of PAVM arising as a complication of graft‐versus‐host disease after allogeneic hematopoietic stem cell transplant.
