Pulmonary endarterectomy after pulmonary infectious embolisms

Pulmonary endarterectomy (PEA) is a well-established procedure in the treatment of chronic thromboembolic pulmonary hypertension (CTPH). The procedure is known to increase functional outcome and to raise the 5-year survival rate. We report 2 cases of pulmonary valve endocarditis and secondary embolisms causing sustained pulmonary hypertension. Both were treated with PEA. In none of the cases, a cleavage between the thrombotic masses and the vessel wall was obtainable, and both attempts were therefore inadequate. Based on our reports, we recommend not attempting PEA in cases of CTPH after infectious embolisms.
