Spontaneously Resolved Systolic Anterior Motion of Native Mitral Valve Leaflet After Transcatheter Mitral Valve Replacement.

Systolic anterior motion of a mitral leaflet can occur by various mechanisms and it is one of the causes of left ventricular outflow tract obstruction after transcatheter mitral valve replacement. We present a case of systolic anterior motion that resolved spontaneously as the anterior mitral leaflet adhered to the prosthesis. ( Level of Difficulty: Intermediate. ).
