Anomalous Mitral Arcade

Abstract

Described in three infants is an anomaly of the mitral valvular mechanism which has the following characteristic: connection of the left ventricular papillary muscles to the anterior mitral leaflet, either directly or through the interposition of unusually short chordae. The condition has been named "anomalous mitral arcade." The anatomic aberration appears to cause incompetence of the mitral valve.
