Giant right sinus of Valsalva aneurysm led to proximal right coronary artery occlusion

Coronary artery stenosis or occlusion due to sinus of Valsalva aneurysm (SVA) is rare, while SVA leading to right coronary artery occlusion is extremely rare (1-3). We present a case of a giant right SVA combined with proximal right coronary obstruction, wherein good results were achieved in the patient with early surgical intervention. Case Report A 56-year-old male was admitted to our hospital with a 6-month history of shortness of breath and palpitation following physical exertion. Transthoracic echocardiography revealed a giant right SVA. The aortic valve was tricuspid with trivial aortic regurgitation and the ascending and descending aorta were within normal limits. The bi-dimensional images confirmed the presence of a right coronary sinus aneurysm with maximum dimensions of 56.82 mm×49.67 mm (Fig. 1). A computed tomography (CT) scan showed the giant right SVA. The proximal right coronary artery (RCA) was not visible, whereas the middle and distal RCA were clearly visible (Fig. 2a-2c). Electrocardiogram was normal.
