Which type of congenital heart defects are acyanotic and have left to right shunts?

The type of congenital heart defects that are acyanotic and have left to right shunts are properly identified as "not trouble defects." These defects typically allow blood to flow from the higher pressure left side of the heart to the lower pressure right side, resulting in extra blood that returns to the lungs rather than being pumped out to the body. This scenario does not create a mixing of oxygenated and deoxygenated blood that would lead to cyanosis, hence they are termed acyanotic.

Common examples include conditions such as atrial septal defects (ASD) and ventricular septal defects (VSD). While they may lead to increased blood flow to the lungs, they usually do not compromise the overall oxygenation of the blood and can often be managed effectively, making them less 'troublesome' compared to other types of heart defects that may result in cyanosis due to right to left shunting. Understanding this concept is crucial since it helps differentiate between various heart defect presentations and their clinical implications.
