Coronary Arteries after Jatene Operation for Transposition of Great Arteries: The Role of CT Coronary Angiography on Follow-up
Antonio Joaquim Marinho-da-Silva
This Short Editorial is referred by the Research article "Evaluation of Coronary Circulation after Arterial Switch Operation".
The correction of transposition of the great arteries (TGA) by the Jatene technique was one of the greatest achievements of cardiac surgery in congenital heart disease. By replacing the transposed arteries in their proper anatomical arrangement, this technique — atrial switch operation (ASO) – achieves a normal spatial arterial relationship. However, this new arrangement requires excision of the coronary artery buttons and their implantation in the new aorta. The difficulty of this step relates to the type of coronary origin and distance to the new insertion site.
Once this anatomical normalization step has been achieved, cardiac functional normalization is sought. The most common post-surgical complications are related to the complexity of associated anomalies (ventricular septal defect (VSD), coarctation of the aorta, valve stenosis, and others), suture sites of the neovessels, pulmonary ramification and dilation of the neoaorta, Not neglectable and object of concern, late complications of either congenital or acquired coronary circulation are well known. The actual incidence of such complications ranges from 0,8% to 27,5% according to reporting series and time of follow-up. ,
