Abstract
A 16-year-old Japanese woman with infective endocarditis was admitted to hospital. An echocardiography exhibited a perivalvular pseudoaneurysm just under the mitral valve. Left ventriculography demonstrated that the aneurysm had a small neck and dyskinetic motion with oppression to the coronary sinus and right coronary artery. (Circ J 2002; 66: 211 - 212)
