Abstract

We report the first documented case of isolated double-orifice mitral valve causing significant left ventricular outflow tract obstruction in an infant. Echocardiography revealed a complete bridge-type double-orifice mitral valve with aberrant chordal insertion into the interventricular septum, producing severe left ventricular outflow tract obstruction. This rare presentation underscores the importance of meticulous echocardiographic assessment for accurate diagnosis and surgical planning.
