Q23.8**: This term is not in ICD-10. Crossmap to higher order term: "Other congenital malformations of aortic and mitral valves"

Coding Notes

This term should not be used for the so-called mitral cleft of a common atrioventricular valve, as this malformation in a patient with a common atrioventricular valve is actually the zone of apposition between the superior and inferior bridging leaflets, and not a divided valve leaflet.
