N2 - We report a case of massive posterior mitral annular calcification causing severe systolic anterior motion of the anterior mitral leaflet and dynamic left ventricular outflow tract obstruction. Mechanism of genesis of systolic anterior motion by this unusual mechanism is illustrated. Importance of recognizing this mechanism and its implications for surgical therapy are discussed. Our patient also had liquefaction necrosis of mitral annular calcification causing its extension into left ventricular myocardium mimicking a tumor.
