Atrial Septal Defect

Many babies born with atrial septal defects do not exhibit signs and symptoms. In adults, signs or symptoms usually begin by age 30, depending on the size of the defect and the flow across. However, for some cases, the signs and symptoms may not occur until years later.

Signs and symptoms of Atrial Septal Defects (ASD) may include:

• Heart palpitations or skipped beats
• Frequent lung infections
• Shortness of breath, especially when exercising
• Fatigue
• Swelling of legs, feet or abdomen
• Stroke
• Heart murmur, a whooshing sound that can be heard through a stethoscope
