LA87.41 Atrioventricular septal defect with communication at the ventricular level only

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

A congenital cardiac malformation that is a variant of an atrioventricular septal defect (atrioventricular canal defect) with an interventricular communication just below the atrioventricular valve, no interatrial communication just above the atrioventricular valve, separate right and left atrioventricular valvar orifices, and varying degrees of malformation of the left sided component of the common atrioventricular valve. Additional information: the bridging leaflets of the common atrioventricular valve are bound to the atrial septum so that the potential for shunting through the atrioventricular septal defect is possible only at the ventricular level and not at the atrial level.
