[The pathology of mitral porcine valves. Echocardiographic relief in 5 cases with intra-para-prosthetic regurgitation (author's transl)].
Echocardiograms were performed in five patients with severe mitral porcine valve insufficiency due to the para-valvular leak in three cases and to a torn and flail cusp in two cases. We believe that diastolic fluttering of the vusps, decrease or increase of diastolic slope of either the stent or the anterior leaflet as well as decrease of the amplitude of motion of the leaflets cannot be regarded as typical diagnostic features as previously described. In our experience specific signs are only represented by a chaotic diastolic movement of one or both leaflets.
