Giant Left Atrial Myxoma Causing Mitral Inflow and Pulmonary Venous Obstruction

Abstract

Introduction and Objective: Atrial myxomas are the most common primary cardiac tumors. Here we report a giant left atrial myxoma with mitral inflow and pulmonary venous obstruction and treated successfully by surgical resection  

Case report: a large left atrial (LA) myxoma of size 9x3.4 cm occupying almost the entire LA with prolapse into the mitral inflow during atrial systole. The soft lobulated tumor was excised with a wide cuff of IAS circumferentially through a bi-atrial approach (Trans right atrial (RA) and LA). CABG was also performed using Left Internal mammary artery  

Discussion: Once a cardiac myxoma is diagnosed it requires surgical excision, and in the event of a large mass, RA access alone does require significant tumor manipulation and may not permit radical resection  

Conclusion: bi-atrial approach ensures good exposure and enables radical excision of the tumor.
