  Figure 2. Echocardiographic Evaluation of Severe Tricuspid Regurgitation and its etiology. (A,B) Extreme tethering and annular dilatation with loss of coaptation, resulting in severe valvular regurgitation. (C,D) Large posterior leaflet prolapse with severe eccentric regurgitant jet.

  Figure 3. Multimodality evaluation for percutaneous tricuspid valve replacement. (A–D) Echocardiographic evaluation of right ventricular function with semi-automated strain measurement. (E–G) Computed tomography cardiac chamber and tricuspid valve evaluation; the patient presented with severe right ventricular (RV) and right atrial (RA) dilatation; tricuspid annulus is highlighted with dotted line.

  Figure 4. NaviGate valve and final result after valve deployment. (A) NaviGate Valve Profile. (B) Fluoroscopic images of NaviGate deployed in tricuspid annulus with relative relations with mitral valve (previous mitral valve replacement) and aortic valve (previous transcatheter aortic valve implantation). (C) Echocardiographic images showing good expansion and stable position of the NaviGate Valve.
