Giant Iatrogenic Pseudoaneurysm of Right Pulmonary Artery Compressing the Left Atrium

Abstract We describe a case of giant pseudoaneurysm of the right pulmonary artery compressing the left atrium after percutaneous pulmonary valve implantation and right pulmonary artery dilatation. Such a complication mimicking an intracavity left atrial mass and treated successfully by stent placement has never, to the best of our knowledge, been reported. (Level of Difficulty: Beginner.)
