title: A case of left atrial myxoma with unusual tumor vascularity.
abstract: A 69-year-old woman presented with a 2-week history of chest pain and mitral and aortic valve replacement 15 and 5 years earlier. Transthoracic echocardiography revealed a well-seated monoleaflet mitral valve and a bileaflet aortic valve with normal function. Cardiac catheterization showed 3-vessel coronary artery disease and an abnormal cluster of new vessels derived from the left atrial circumflex and posterior ventricle branches. Two- and 3-dimensional transesophageal echocardiography identified a semi-mobile oval left atrial mass with multiple internal cystic spaces, attached to the fossa ovalis region in the interatrial septum. The mass was resected. The pathological diagnosis was atrial myxoma.
