Transcatheter aortic valve implantation in unicuspid aortic valve stenosis

Figure 1. Illustration of echocardiogram and CT images. Transthoracic echocardiogram parasternal short-axis (A, Moving image 1) and three-chamber views (B, Moving image 2) showing calcific unicuspid, unicommissural aortic valve with an eccentric opening (arrow). Computed tomography maximum intensity projection (MIP, C) and volume-rendered (VR, D) images showing an unicuspid unicommissural valve and absence of raphae. E) Post TAVI, TTE parasternal long-axis images showing the prosthetic valve in situ. High-resolution CT MIP and VR images showing oval configuration and good expansion of the prosthetic valve (F-H, star, Moving image 3). Post TAVI, TTE five-chamber image showing the prosthetic valve in situ and showing ...
