Interatrial communications (atrial septal defects)

Patients require endocarditis prophylaxis for the first 6 months after device or surgical closure of an interatrial communication, and indefinitely if they have unrepaired cyanotic heart disease. Patients should report symptoms of fever, chest or abdominal pain, vomiting, syncope, or fatigue immediately. Restrictions on physical activities are generally not required. Patients with Eisenmenger syndrome should avoid pregnancy, dehydration, and high altitudes.
