[Stent implantation as therapy of first choice in adults with coarctation]

Stent implantation for coarctation of the aorta is an alternative to surgery or balloon dilation. We report our results in 12 patients with a median age of 22 years (10 to 28 years) and a body weight of 60 kg (32 to 97 kg). Nine patients had native stenosis and three had recoarctation after surgery. Invasively measured systolic pressure gradients ranged from 20 to 100 mmHg. Nine patients suffered from brachiocephalic hypertension. Eleven implantations were successful with a median dilatation of 17 mm (15-25 mm). Residual gradients were 0-5 mmHg in seven patients, 5-10 mmHg in three and 15 mmHg in one patient with postoperative recoarctation. Twenty-one months (2-37 months) after intervention, no hemodynamically relevant intimal proliferations, no restenosis, and no aneurysms were present. Thus, stent implantation is a very promising therapy for coarctation of the aorta in adults and is on its way to becoming the therapy of first choice.
