[Coronary angioplasty in a 12-year-old child]

Coronary artery disease is seldom reported in patients under 20 years of age. We present here the case of a 12 years old male, with systemic high blood pressure who had 2 episodes of typical chest pain. He underwent a submaximal exercise treadmill test which was negative. He then underwent cinecoronarography that revealed a 78% (measured by the caliper) obstruction in the proximal segment of the circumflex coronary artery with 3 mm of extension. The left coronary artery and the left ventricle were normal. The patient was subjected to a percutaneous transluminal coronary angioplasty, which was successful and left a 12% (measured by caliper) residual stenosis. The late angiographic restudy (5 months after the procedure) showed the maintenance of the immediate success of the procedure.
