A Heart Inside the Heart: Blood Cyst of Mitral Valve

Abstract

We report a case of giant blood cyst originating from the anterior mitral valve leaflet, which was discovered during a two-dimensional echocardiography examination performed for investigation of a systolic murmur in a 34-year-old healthy man. Three-dimensional microbubble-enhanced images showed a heart-shape appearance that may be pathognomonic for blood cyst of the mitral valve.
