Sarcoma Resection with Complete Removal of Left Atrial Posterior Wall

Abstract

We report a case of recurrent left atrial (LA) intimal sarcoma invading pulmonary veins (PV) which was treated by a novel surgical approach-resecting LA wall and PVs down to segmental levels, and then creating neo-LA using lung hilum and posterior mediastinal soft tissue without further reconstructive procedures. This surgical approach may be useful in selected cases with primary cardiac malignancy involving LA and PVs in the aim of achieving complete resection of the tumor. Left heart sarcoma is an extremely uncommon but lethal disease which poses challenges to physicians due to its equivocal presentation, limited treatment option and dismal prognosis. Although the mainstay of treatment is a complete resection, it is technically demanding due to a lack of extensive experience in cardiac malignancy surgery and its very location or involvement in vital structures. Therefore, establishing a creative surgical strategy to overcome aforementioned obstacles and to achieve complete resection with tumor-free resection margin is needed. Here in, we report a case of recurrent left atrial sarcoma which was removed by noteworthy surgical technique.
