3D reconstruction of cardiothoracic imaging in an asymptomatic young woman with TS. She had been “followed” with cardiac ultrasound in the years preceding admission to the NIH TS protocol. The cardiothoracic surgeons reviewed her imaging and recommended surgery on a semiurgent basis (she was considered a “walking time bomb”). She had a BAV, ascending aortic (Aao) aneurysm of 4.5 cm and descending aortic aneurysm of 6 cm involving the origin of the left subclavian artery (LSCa). Image courtesy of Marcus Chen, NHLBI.
