Cyanotic Heart Disease

Pronunciation: sy-ah-NOT-ik

A category of congenital heart defects that result in decreased oxygen levels in the blood, causing bluish discoloration.

Full Definition

Cyanotic heart disease refers to congenital heart defects that cause mixing of oxygenated and deoxygenated blood, resulting in reduced oxygen saturation and characteristic blue discoloration of the skin and mucous membranes. These conditions typically involve abnormal blood flow patterns or structural anomalies that prevent proper oxygenation. Editors should distinguish this from acyanotic heart disease and ensure proper capitalization in formal medical writing.

Usage

Usage note: Capitalize when referring to the specific disease category; lowercase when used descriptively.
