case_images: Transoesophageal echocardiogram (TOE) demonstrated a 3 x 2 cm right atrial mass which was continuous with the coronary sinus (Fig. 1a and b). High-velocity flow was noted from the mass in systole and diastole emptying into the right atrium from two distinct areas, with a maximum gradient of 70 mmHg (Fig. 1c).
