RHT are often found in the setting of severe bilateral pulmonary embolisms (PEs). Patients with RHT in transit often have higher heart rates and lower blood pressures and exhibit more right ventricular dysfunction compared with patients who present with PE without RHT in transit., We describe two cases of right atrial thrombi in transit diagnosed using echocardiography. Despite intravenous thrombolysis and inotropic support, the patients developed cardiopulmonary collapse and died.
