Prosthetic Mitral Valve X Ray. The risk of thromboembolic events is higher with mechanical than with bioprosthetic valves, higher with mitral than with aortic prosthetic valves, and higher in the early (3 months) versus late postoperative phase. Management depends mainly on the occurrence of a thromboembolic event and the size of the thrombus (figure 35.9.7).

The pressure gradient across normally functioning prosthetic valves depends upon both the size of the prosthesis as well as its profile. Though prosthetic valves are seen well on cxr, they can be evaluated better by fluoroscopy. Sometimes the annulus alone is replaced as seen in annuloplasty rings.

Prosthetic mitral valve replacement using a transseptal approach via a median sternotomy was successfully performed in the patient. The chest radiograph can localize the great majority of valve prostheses to the aortic, mitral, or tricuspid positions, and it can usually determine whether the prosthesis is mechanical or bioprosthetic.
