Heart birth defects can be diagnosed by a variety of tests. If a defect is suspected in an unborn baby, the doctor can do a fetal echocardiogram, or an ultrasound in the womb. After birth, a regular echocardiogram may be used. In addition, an electrocardiogram, which tests heart activity, may be used. Chest x-rays can show if there are issues with the heart, while pulse oximetry tests can tell if there is not enough oxygen in the blood. Lastly, a doctor may use a catheter to the heart to complete additional testing.

How are heart birth defects diagnosed?

How can physical and emotional stress affect my heart health?
Brigham and Women's Hospital answeredStrenuous physical exertion could certainly increase the demands of the heart muscle for oxygen -- one way in which angina attacks occur. Rises in blood pressure and heart rate, as well as the force of heart action with extreme effort or emotion, might also promote rupture of atherosclerotic plaques, considered a common cause of heart attacks. With respect to stent thrombosis, some hormones that are elevated during physical and other stresses may make blood platelets more "sticky," potentially precipitating blood clot formation in stents.
What are venovenous collaterals?
Cyanotic single ventricle congenital heart disease is a heart defect that is present at birth in which only one lower chamber of the heart pumps blood. The term cyanotic describes the bluish color of the child’s skin that results from a lack of oxygen in the bloodstream.
At some stages of palliative (symptom-reducing) surgery for cyanotic single ventricle congenital heart disease, small veins may open up and become larger. The small veins that enlarge are called venovenous collaterals. They allow blue blood to bypass the lungs and go directly back to the heart. This may result in an excessive blueness (cyanosis) of the child’s skin.
Coils and devices delivered within the blood vessel via a thin tube called a catheter can be used to stop (occlude) blood flow from bypassing the lungs. When the blood is able to enter the lungs, it can pick up oxygen that is necessary to support healthy functioning, and the child’s skin will return to a normal color.
