Click 11 year old male with ruptured aneurysm arising from the left sinus of Valsalva. Echocardiographic images in parasternal short axis and modified four chamber views show ruptured aneurysm arising from the left sinus with fistulous track between the left sinus and the right atrium. Note segment of dilatation of the track just proximal to the opening in the posterior wall of right atrium. (Philips Envisor ultrasound machine using S4 probe with 2-4 MHz frequency).

Click 11 year old male with ruptured aneurysm arising from the left sinus of Valsalva. 64 slice cardiac CT imaging in axial plane with 0.625mms slice thickness, show ruptured aneurysm arising from the left sinus with long ``wind sock shaped`` fistulous track extending between the aorta anteriorly and the left atrium posteriorly. Note segment of gross dilatation of the track just proximal to the opening in the posterior wall of right atrium. (GE Light speed VCT 64slice CT scanner. Protocol: 450 mAs, 120 kV, 0.625 mm slice thickness, 30ml of Omnipaque 350mg I/ml).
