'surgical correction'

Atrial Septal Defects (ASDs) that aren't diagnosed until adulthood can damage the heart and lungs, shortening life. Many babies born with ASDs don't have symptoms. By the age of 30, adults may notice symptoms such as shortness of breath, heart palpitations, fatigue, swelling in the legs, feet or abdomen and heart murmurs. Small ASDs may close on their own. Medium-to-large-sized ASDs may need closure by device or surgical correction.
