about 80 y old patient with distinct dyspnoea, recurrend lung oedema and tachykardia. In TTE we found a calcification of posterior cup of mitral valve with severe mitral valve insufficiency. In TEE we could demonstrate a mitral valve prolaps of posterior cup: it seems that there is a \"fixed\" prolaps of posterior cup caused by calcification. The apex of posterior cup shows the picture of flail leaflet. The mitral valve insufficiency is high grade with distinct regurgitation in the pulmonary veins. What do you think? Is this a typical picture of mitral valve prolaps?
