It is present since birth and leads to low oxygen level in blood. A cardiac shunt is an abnormal flow of blood between the chambers of heart. [tandurust.com]

Another method for predicting the type of shunt present is the age at presentation. VSDs and atrioventricular septal defects (AVSDs) present early in life, usually in infancy. [radiologykey.com]

• Asymptomatic

  Clinical findings Patients are usually asymptomatic until complications occur (see below). [amboss.com]

  The severity of the condition depends on the size of the shunt but is usually asymptomatic in infants. [healthhype.com]

  In isolation, these defects may be asymptomatic, or they may produce symptoms which can range from mild to severe, and which can either have an acute or a delayed onset. [ipfs.io]
