Surgical repair of a leaking double postinfarction left ventricular pseudoaneurysm

the effectiveness of adjuvant therapy for these aggressive tumors. The role of adjuvant radiation therapy is not well defined but is generally advocated because it might decrease the incidence of recurrent tumor. Primary PA sarcoma has a predilection to result in metastatic disease because of its tendency to embolize into the pulmonary arterial tree. Chemotherapy might be effective against microscopic metastatic disease and might decrease the burden of recurrent pulmonary and other systemic disease; however, there has been limited experience with this in the past. In summary, we present 2 cases of primary PA sarcoma that mimicked pulmonary thromboembolic disease. In both patients the diagnosis of PA sarcoma was made only after pathology was reviewed postoperatively. Despite diagnostic, operative, and oncologic advances over the last few decades, PA sarcoma still remains a diagnostic dilemma associated with a dismal prognosis.
