title: Value of transesophageal echocardiography in the diagnosis of compressive, atypically located pericardial cysts.
abstract: Pericardial cysts are not common and rarely cause symptoms. We report 2 cases of atypically located pericardial cysts with hemodynamic compromise because of the direct compression of the pulmonary veins and the right pulmonary artery. In the first case, transesophageal echocardiography (TEE) disclosed a round cystic mass compressing the posterior wall of the right pulmonary artery, with blood flow reduction in the right lung. Because of the symptoms, the pericardial cyst was drained and the patient had an uneventful 1-year follow-up. In the second case, a large cystic mass compressing the left atrium and the pulmonary vein outflow was clearly shown by TEE in a patient with severe respiratory distress, cyanosis, and low blood pressure. A left ventricular thoracotomy was performed with the drainage of 500 mL serous fluid from the cyst.
