Follow-up of Arterial Switch Operation

Abstract

This report describes the experience of the Leiden University Hospital with the arterial switch operation for transposition of the great arteries, with and without ventricular septal defect, and for the Taussig-Bing-anomaly. The longest follow-up was 13 years and 9 months. Follow-up shows good results with almost all surviving patients in functional class I and with a sinus rhythm. Supravalvular pulmonary artery stenosis is noted in some of the patients but is almost always mild and does not show any tendency to progression. Insufficiency of the aortic valve is seen less frequently. Until now it has not caused great concern but, of course, follow-up is still limited.
