Giant Coronary Sinus Caused by Absent Right and Persistent Left Superior Vena Cava and Severe Tricuspid Regurgitation

ABSTRACT

Dilated coronary sinus is often visualized on echocardiography in patients with right sided heart disease as well as with persistent left superior vena cava. We observed a case of markedly dilated coronay sinus caused by persistent left superior vena cava and severe tricuspid regurgitation. The diagnosis was made by transthoracic echocardiography with intravenous injection of agitated saline into both arm.
