about 75 y old patient with condition after implantation of prosthesis in aortic position about 10 month ago. Actually the patient has no clinical afflictions, in TTE I saw a distinct increase of
transprosthetic gradient (PGmean about 35-40 mmHg, LV-EF about 55%) and an large regurgitation jet (PHT 380 msec). In TEE so we could demonstrate an obstruction of the posterior disk, that explains
the incrase of transprothetic gradient and distinct regurgitation jet. You can see in the 3D-reconstruction, that the post disk doesn´t move. This finding was confirmed by continious x-ray, where we
could see no movement of one disk.
retrospectively, the reason for abstruction pf prothesis was an inappropriate anticoagulation with warfarine.
about 70 y old patient with prolonged dyspnea and interstitial oedema of lung. A condition of mitral valve replacement (Hancock biological mitral valve prosthesis) is known. In TTE (not shown) I saw a
distinct regurgitation beside the mitral valve prosthesis. So in TEE I could demonstrate a distinct paraprosthetic leckage with regurgitation in left upper pulmonary vein. 3D-reconstruction could
localised the paraprosthetic leckage between mitral valve prosthesis and LAA.
