All the following are Congenital heart diseases with Oligemic Lung fields except:
**Core Concept**
Congenital heart diseases (CHDs) can be broadly classified into two groups based on their impact on pulmonary blood flow. Some CHDs result in increased pulmonary blood flow (e.g., atrial septal defects, ventricular septal defects), while others lead to decreased pulmonary blood flow (e.g., pulmonary stenosis, tetralogy of Fallot). The latter group is characterized by oligemic lung fields, which are indicative of reduced blood flow to the lungs.
**Why the Correct Answer is Right**
Oligemic lung fields are typically seen in CHDs that involve obstruction to blood flow from the right ventricle to the pulmonary artery or from the left ventricle to the systemic circulation. Tetralogy of Fallot (TOF) is a classic example of a CHD with oligemic lung fields due to the presence of pulmonary stenosis, which restricts blood flow to the lungs.

**Clinical Pearl / High-Yield Fact**
A key clinical feature of CHDs with oligemic lung fields is the presence of cyanosis, which is a bluish discoloration of the skin and mucous membranes due to reduced oxygenation of the blood. Cyanosis is typically more pronounced in CHDs with significant obstruction to blood flow to the lungs.
