Sinus of Valsalva Aneurysm (SVA) is an aortic root anomaly, consisting of a lack of continuity between the aortic media and the aortic annulus, caused by a structural deficiency of muscular and elastic tissue. We present the case of a 49-year-oldman with atypical chest pain. Echocardiographic imaging described a giant unruptured aneurysm of the right sinus of Valsalva which was confirmed by cardiac computed tomography and coronary angiography. The obstruction of the right coronary artery without intravascular thrombosis and the compression of the right ventricular outflow tract with dynamic obstruction gradient represent the particularities of our case.
