Congenitally corrected transposition of the great arteries with a patent foramen ovale in an 81-year-old man--a case report.

Congenitally corrected transposition of the great arteries is a rare cardiac anomaly with a poor prognosis. In this report, the authors describe an 81-year-old man admitted to the hospital with generalized fatigue, chest pain, and cyanosis. Computed tomography and cardiac catheterization revealed corrected transposition of the great arteries. Transesophageal echocardiography disclosed moderate right atrioventricular regurgitation and a right-to-left shunt across a patent foramen ovale during systole. Because this patient had no other congenital cardiac anomalies, the right-to-left shunt through the patent foramen ovale was thought to be the major cause of cyanosis.
