Research output: Contribution to journalArticlepeer-review


A 71-year-old man with coronary artery disease, sarcoid uveitis, and recurrent ventricular tachycardia treated with implantable cardioverter-defibrillator presented with increasing dyspnea for several months. Echocardiography showed a large echogenic mass causing severe narrowing of the proximal main pulmonary artery and a resultant gradient of 65 mm Hg. Ventilation-perfusion scintigraphy showed diffusely decreased perfusion of the left lung and an additional mismatched segmental perfusion defect in the left upper lobe. Cardiac MRI could not be performed because of the implantable cardioverter-defibrillator.
