title: Transcatheter double stent implantation for treatment of middle aortic coarctation syndrome.
abstract: A 13-year-old boy presented with severe systemic hypertension. His upper limb blood pressure measured 190/100 mm Hg and lower limb blood pressure measured 98/64 mm Hg. The brachial pulses were bounding and femoral pulses were not palpable. Echocardiography and magnetic resonance angiography confirmed middle aortic syndrome. There was severe diffuse thoraco-abdominal coarctation with continuous Doppler run-off. Cardiac catheterization was undertaken and using a retrograde approach two Advanta V12 stents were implanted in the complex thoraco-abdominal coarctation. The gradient across the coarctation was reduced from 80 to 40 mm Hg gradient with a significant improvement in the luminal diameter of the aorta. His upper limb blood pressure reduced to 142/78 mm Hg six weeks later.
