Coarctation of the aorta is nowadays rarely observed among adult population, as it is usually detected and treated during infancy. The natural history of this disease however is known to lead to early death due to the consequences of severe arterial hypertension. We report on 3 patients older than 30 years, recently operated on in our cardiosurgical units. Two of them were foreigners recently arrived in Switzerland, of 46 and 32 years old respectively. The medical examination highlighted severe hypertension and bilateral absence of femoral pulses. The third patient was a Swiss citizen and had a similar examination. Chest X-rays clearly showed rib notching, and the suspected diagnosis was confirmed with angiography. Three different surgical techniques were chosen, according to the peroperative situation. In one case, the stenosis was resected and an end-to-end anastomosis could be performed. In another case, the occlusion was complete and extended over 3 centimeters. The resected segment was replaced by a prosthetic graft. In the third case, we performed a synthetic patch graft aortoplasty. Postoperative care were simple in every cases. Coarctation of the aorta must be evoked among the possible etiologies of severe hypertension, as the surgical treatment is of real benefit and with reduced morbidity.
