A 61-year-old man was referred for mild exercise intolerance. He had a previous history of chronic obstructive pulmonary disease, arterial hypertension and was an ex-smoker. Physical examination revealed a systolic murmur and his electrocardiogram showed sinus rhythm and an incomplete right bundle-branch block. A transthoracic echocardiogram was performed and showed mild left ventricular hypertrophy, mild rheumatic mitro-aortic disease, left atrial (LA) enlargement. and dilated right ventricle (figure 1 A-D), dilated coronary sinus (CS) (panel A, small arrow) and a prominent CS flux into right atria (RA) (panel C, D, large arrow). Transoesophageal echocardiography revealed a communication between the LA and the RA through a dilated coronary sinus (panel E, large arrow). A cardiac computed tomography confirmed the diagnosis of an unroofed coronary sinus showing the shunt between LA and RA through a dilated CS (panel F, large arrow).
