A patient with severe hypoxia secondary to a large iatrogenic pulmonary artery to pulmonary vein fistula. BMJ Case Reports, 2014. https://doi.org/10.1136/bcr-2014-2038641757-790Xhttps://hdl.handle.net/1805/11664Pulmonary arteriovenous malformations are uncommon communications between the pulmonary arteries and veins, most commonly associated with hereditary haemorrhagic telangiectasia. They can also be associated with a variety of other conditions, and can be single or multiple. We present a case of a female patient with a history of coronary artery bypass grafting and mitral valve repair, who presented to the hospital with severe hypoxia. She was found to have a large pulmonary artery to superior pulmonary vein fistula that was successfully repaired using a septal occluder. To our knowledge, this is the first case of a large pulmonary artery to superior pulmonary vein fistula following mitral valve repair.en-USPublisher's PolicyPulmonary arteriovenous malformationsHypoxiaArticle
