    Abstract:
    BACKGROUND: The aim of this study was to determine the outcome after surgical repair of aortic coarctation in adults, analysing its effect on arterial blood pressure. METHODS: Twenty-five adults (9 women, 16 men), mean age 43.4 years (19 to 70 years), underwent aortic coarctation surgical repair. All patients suffered from preoperative hypertension. Mean blood pressure was 182/97 mm Hg. Sixteen (64%) patients demonstrated reduced load capacity. Operative technique was resection and end-to-end anastomosis for 5 patients (20%), interposition of a Dacron-tube graft for 3 patients (12%), Dacron-patch dilatation was performed in 7 (28%) patients, and in 10 (40%) patients we performed an extra-anatomical bypass graft. RESULTS: Early mortality occurred in 1 patient (4%). The mean blood pressure was reduced [systolic 182 mm Hg vs. 139 mm Hg (p < 0.001), diastolic 97 mm Hg vs. 83 mm Hg (p < 0.001)] in all patients. In 12 patients, blood pressure normalized immediately after surgery, in 7 patients it remained slightly elevated (systolic blood pressure between 140-160 mm Hg), and 1 patient suffered from prolonged arterial hypertension. Preoperatively, all patients were treated with antihypertensive drugs. Eleven of 20 patients received long-term medication during follow- up. In the remaining 4 patients, medication lists were unobtainable in retrospect. The mean follow-up was 7.1 years (min. 1.0 years; max. 16.6 years). One patient (5%) died from cardiac failure 12.4 years after the operation. On average, the New York Heart Association (NYHA) class was improved by 0.92. CONCLUSIONS: The surgical repair of aortic coarctation in adults can be performed with low surgical risk. Surgery reduces hypertension and permits more effective medical treatment.
