title: Neovascularization and associated fistula formation in a left atrial myxoma: evaluation with multidetector computed tomography.
abstract: Although angiographically detectable neovascularity is being reported with increasing frequency in patients with cardiac myxoma, associated coronary fistula to the cardiac chamber has not been described. We report a 62-year-old woman in whom cardiac computed tomography (CT) enabled the noninvasive diagnosis of a left atrial myxoma with neovascularization arising from the left circumflex artery and the formation of an unusual fistula into the left atrial cavity, with concomitant evaluation of the coronary arteries. Careful suture ligation of a supplying coronary branch in the atrial septum was performed during tumor excision to prevent the development of intra-atrial steal.
