Right coronary artery aneurysm diagnosed with multislice computed tomographic angiography. (Images in Cardiology).(Brief Article)

An 83 year old man presented with shortness of breath. Physical examination revealed a raised jugular venous pressure and atrial fibrillation with a rapid ventricular response. A provisional diagnosis of congestive cardiac failure was made and treatment with digoxin and diuretics initiated. A transthoracic echocardiogram demonstrated a large "doughnut" shaped extracardiac mass compressing and displacing the right atrium.

Non-invasive coronary angiography was performed using multislice helical ("spiral") computed tomography (CT). The breath hold required for a scan time of 31 seconds was well tolerated. Following contrast injection images were acquired using a gantry …
