Right heart thrombus (RHT) accompanied by chronic thromboembolic pulmonary hypertension (CTEPH) is a rare entity. RHT may develop in the peripheral veins or in situ within the right heart chambers. The diagnosis of RHT is challenging, since its symptoms are typically non-specific and its imaging features resemble those of cardiac masses. Here, we report two cases of RHT with CTEPH that presented as right ventricular masses initially. Both patients underwent simultaneous pulmonary endarterectomy (PEA) and resection of the ventricular thrombi. Thus, when mass-like features are confirmed by imaging, RHT should be suspected in patients with CTEPH, and simultaneous RHT resection is required along with PEA.
