Long-term outcome of sirolimus-eluting stent implantation for left main coronary artery stenosis in infancy.

Drug-eluting stents (DES) have markedly reduced the incidence of coronary in-stent restenosis. However, DES may be still vulnerable to coronary thrombus, and the long-term outcome remains unknown, especially in infancy. Here, we present a 9-month-old infant, who developed severe stenosis of the left main coronary artery after surgery for Brand-White-Garland syndrome, and was successfully treated with DES. He was healthy and his cardiac function had improved to the normal level at 6 years old. An angiographic examination and computed tomography showed the complete persistence of DES and no evidence of intimal thickening.
