Left Valsalva Sinus Aneurysm Rupture into Left Atrium and Aortic Valve Prolapse Confirmed with Transesophageal Echocardiography

We report a very rare case of left Valsalva sinus aneurysm rupture into left atrium in a 55-year-old man with severe aortic regurgitation caused by aortic valve prolapse. The Valsalva sinus aneurysm rupture was clearly visualized with transesophageal echocardiography performed to further delineate the aortic valve pathology. The 3-dimensional reconstruction of multislice computed tomography images nicely visualized the left Valsalva sinus aneurysm.
