title: Right atrial myxoma with right to left shunt and coronary artery disease.
abstract: Surgical treatment of a right atrial myxoma with a right-to-left shunt and coronary artery disease was successfully performed in a 61-year-old man. The interatrial shunt occurred through a patent foramen ovale and was the result of a high central venous pressure due to tricuspid stenosis and regurgitation. Instead of right heart catheterization and cardioangiography, we chose an intraoperative blood-gas study to diagnose the intracardiac shunt. Preoperative polycythemia and hypoxemia were improved after removal of the tumor and closure of the patent foramen ovale.
