Long Term Outcomes of Arterial Switch Operation At The Transposition of the Great Arteries

Purpose: In this study, we present an assessment of late term outcomes of patients with the diagnosis of transposition of the great arteries of who were applied arterial switch operation between 2007 and 2017 in our clinic.Methods: Medical records of the patients who were applied arterial switch operation and kept in long term follow-up, were analyzed retrospectively. The mean follow-up time of the patients was 62 months. The patients after discharge were examined via transthoracic echocardiography with regard to the necessity of reoperation requirement. Results: There was no mortality in late term follow-up. Functional classification of the patients were NYHA I and II. Only in three patients (5.1%), complications that requiring surgical treatment were observed in long term follow-up. Enlargement operation with a patch was applied to two patients due to a stenosis in pulmonary artery. A valve sparing reconstruction with a Dacron patch was applied to one patient owing to neoartic root dilatation. Discussion: Despite arterial switch operation are able to be successfully performed with a high long term survival rate in experienced centers in the treatment of transposition of the great arteries, the patients should be kept in close follow-up considering the development of possible late complications.
