Concomitant right atrial hemangioma resection with lvad implantation first-in-human experience

Abstract

Cardiac hemangiomas are exceedingly rare, comprising only 5% to 10% of benign cardiac tumors. We report a patient with a large right atrial mass and end-stage heart failure with severe left ventricular dysfunction. Echocardiography revealed a mass obstructing tricuspid inflow. Contrast-enhanced computed tomography and cardiac magnetic resonance confirmed a 100 mm × 96.5 mm × 104 mm lobulated mass. Simultaneous tumor resection and left ventricular assist device implantation were performed. Histopathologic examination confirmed a cardiac hemangioma. The patient showed significant improvement and remained alive at 3-year follow-up, with only minor gastrointestinal bleeding episodes.
