Natural history of complex transposition of great arteries in an adult: a case report

AbstractBackground:Transposition of the great arteries is the most common cyanotic cardiac lesion in newborns. Transposition of the great arteries without surgical correction is fatal during the first year of life. Contemporary outcome studies have shown that survival rates after surgery are excellent and most patients live to adulthood.Case summary:Woman with complex transposition of the great arteries with atrial and ventricular septal defects and subvalvular and valvular pulmonary stenosis, who has survived until the age of 31 years without surgery. The diagnosis was made by echocardiography and cardiac magnetic resonance. She underwent successful corrective surgical treatment after this age, by means of a Jatene operation.Conclusion:In transposition of the great arteries patients, a high index of cases dies in the first month of life. Our case represents a natural history of the complex transposition of the great arteries. Non-invasive imaging studies are very useful for the diagnosis and follow-up of patients with transposition of the great arteries, especially echocardiography and cardiac magnetic resonance. In our case, the multimodality approach and the corrective surgery allowed her to survive.
