Coding Notes

Shone’s syndrome consists of multilevel hypoplasia or obstruction of the left-heart. The syndrome is based on the original report from Shone that was based on analysis of 8 autopsied cases and described the tendency of these four obstructive, or potentially obstructive, conditions to coexist. Only 2 of the 8 cases exhibited all four conditions, with the other cases exhibiting only two or three of the anomalies.
