title: Acquired pulmonary artery branch stenosis caused by pulmonary thromboembolism.
abstract: We present a case of acquired pulmonary artery branch stenosis caused by pulmonary thromboembolism. The patient presented with symptoms mimicking aortic dissection. An emergent transesophageal echocardiogram showed a high gradient across the right pulmonary artery along with mobile thrombi. The vital importance making an accurate diagnosis and ruling out aortic dissection is emphasized in view of the need for urgent heparinization or thrombolysis for pulmonary thromboembolism as this is contraindicated in aortic dissection.
