Evaluation of syncope in adult congenital heart disease.

Approximately one million adults in the United States have congenital heart disease. The practitioner who sees one of these patients presenting with syncope must have a thorough understanding of: the underlying disease process; the associated congenital heart abnormalities; the type of surgery performed; the potential surgical residua; and the natural and unnatural history of this type of heart disease. Several types of congenital heart disease including: atrial septal defects; ventricular septal defects; left-sided obstructive lesions; Ebstein Anomaly; tetralogy of Fallot; and transposition of the great arteries are reviewed.
