ballerina-foot pattern

bal·le·ri·na-foot pat·tern

a vigorous posteromedial contraction of the left ventricle coupled with convexity anteriorly sometimes resulting from poor contraction of the opposing anterior wall; it is the most frequent dyssynergy observed in the prolapsed mitral valve leaflet syndrome (even with a normal anterior wall) and produces a configuration of angiographic dye in the right anterior oblique projection resembling a ballerina's foot.
