Your doctor will check your baby’s heartbeat with the help of a stethoscope, take a complete medical history, and perform other tests.
A tracheal echocardiogram (TEE) is taken by numbing the throat and then pulling a thin tube with an ultrasound device down the throat and into the esophagus, close to the heart.
The echocardiogram is an ultrasound of the heart when saline bubbles are injected into the bloodstream.
Radio and magnetic waves are used to take pictures of the heart in MRI.
