Communication between left ventricle and right atrium – http://id.who.int/icd/entity/1370033158

A congenital cardiac malformation characterised by deficiency of the atrioventricular component of the membranous septum permitting shunting of blood from the left ventricle to the right atrium. Additional information: this is an isolated deficiency of the atrioventricular septum without a common atrioventricular junction and its associated spectrum of lesions, such as a common atrioventricular valve, with characteristic interatrial and-or interventricular septal communications. This Communication between left ventricle and right atrium (sometimes referred to as a Direct Gerbode defect) may be confused with ventricular septal defects where a deficiency of tricuspid valvar tissue permits ventriculo-atrial shunting subsequent to initial interventricular shunting (left ventricle to right ventricle to right atrium), the so-called Indirect Gerbode defect.
