[Long-term results of anatomic repair of transposition of great vessels].
The long-term complications after anatomical repair of transposition of the great arteries (TGA) were analysed in a prospective study of 30 successive patients, from August 1996 to October 1999, who were presumed asymptomatic and investigated 10 years after surgery. All underwent clinical examination, ECG, stress Thallium 201 myocardial scintigraphy, Doppler echocardiography, Holter ECG, pulmonary perfusion scintigraphy, right and left cardiac catheterization with selective coronary angiography. Five patients had coronary lesions (4 thromboses and 1 coronary-pulmonary artery fistula). The other abnormalities observed were mild bilateral stenosis of the two pulmonary arteries (1 case), grade 1 aortic regurgitation (6 cases), including 1 case of aortic root dilatation. Type B to E coronary circulations (Yacoub classification) were not significantly correlated with coronary artery disease in this series (p = 0.06). For the diagnosis of these lesions, myocardial scintigraphy and Doppler echocardiographic detection of wall motion abnormalities had a sensitivity of 50% and respective specificities of 88% and 35%. Long-term results after anatomical repair of TGA are satisfactory. However, the high incidence of coronary lesions makes regular follow-up and systematic coronary angiography necessary in all children.
