Coarctation of aorta is a rare cause of secondary hypertension, premature death will occur if no appropriate treatment is given. Before 1980, the only effective treatment was surgery, and recurrent stenosis was frequent. After then several works on percutaneous transluminal angioplasty of this disease were reported, with promising short-term and long-term results, especially in children and young adults. This report concerns a 19-year-old male who had hypertension for four years; the hypertension was caused by coarctation of the aorta, confirmed by cardiac catheterization and angiography. Average blood pressure (BP) of his upper extremities was 200/110 mmHg which dropped to 150/90 mmHg immediately, and still two years, after angioplasty, whereas BP of the lower extremities maintained at about 150/80 mmHg measured by Korotkoff technique. Follow-up transesophageal echocardiography found no coarctation or aneurysm at the dilatation site one year later. Magnetic resonance imaging, performed two years later, showed an almost normal aortic wall at the coaxctation. The postoperative course was uneventful, and patient follow-up at the cardiology clinic has regularly shown an average BP around 150/80 mmHg.
