A 58-year-old man admitted with atypical chest pain, and an echocardiogram showed a tumor in the left atrium. The tumor widely originated from the interatrial septum and the superior-anterior inner surface of the left atrium did not disturb a mitral valve motion. A right coronary angiogram demonstrated feeding arteries of the tumor. The right parasternal skin incision was made and the tumor was completely removed through the interatrial incision under the video-assisted fiberscopic system. Nd-YAG laser was exposed on the tumor-resected surface for laser coagulation resulting in tumor necrosis. Pathological examination revealed myxoma with rich neovascularization. On the 12th day the patient discharged without complications.
