Case presentation Figure 1. Chest radiograph showing widened mediastinum by a right para-tracheal soft tissue shadow (arrow) A 62-year-old male patient complaining of atrial fibrillation was referred for pre-ablation workup. Plain chest radiography demonstrated a right paratracheal soft tissue shadow mimicking a mediastinal mass (figure 1). Contrast-enhanced computed tomography (CT) revealed fusiform aneurysmal dilatation of the upper segment of the superior vena cava (SVC) starting from its origin at the confluence of the right and left brachiocephalic veins and ending 3 cm above the cavo-atrial junction (figure 2), with maximal axial dimens

Echocardiography showed a right coronary (anterior) aortic sinus aneurysm protruding into the right ventricle with a large (1.5 cm) fistula (figure 1). Biventricular size and function was normal; there were no other structural cardiac defects or evidence of infective endocarditis seen. Percutaneous device closure was not possible due to the large size of the aneurysm. He underwent cardiac surgery. There was a right coronary (anterior) aortic sinus aneurysm, which had ruptured into the right ventricle. Patch closure with bovine pericardium and aortic valve replacement with a 25 mm St. Jude Regent™ mechanical valve were Figure 1. Echocardiogr

Figure 1. Parasternal long axis two-dimensional echocardiogram, showing a 6.6 cm aneurysm of the sinus of valsalva (right coronary sinus) Aneurysms of the sinus of valsalva are rare and almost always originate from the right or non coronary sinuses. Unruptured, they normally remain clinically silent (detected by routine echocardiography) but can cause right ventricular outflow tract obstruction, aortic regurgitation and myocardial ischaemia from coronary artery compression. Rupture of these aneurysms can occur into any adjacent cardiac chamber and the clinical presentation may vary according to the location of this rupture. The definitive man
