Long-term observation of adults after successful repair of aortic coarctation

INTRODUCTION: Despite successful repair of aortic coarctation, cardiovascular complications occur. AIM: To analyse type and frequency of late complications and their impact on exercise capacity in adults after aortic coarctation repair. MATERIAL AND METHODS: Fifty-eight adults after aortic coarctation repair, 36 male, median age 27.46 ±10.57, were compared to 30 healthy volunteers. Physical examination, transthoracic echocardiography, carotid intima-media thickness measurement, cardiopulmonary exercise test and 24-hour ambulatory blood pressure monitoring were performed. RESULTS: = 0.046. There was no association of any cardio-pulmonary parameters with time from surgery, type of operation or echocardiography results. CONCLUSIONS: Adults after aortic coarctation repair suffer from arterial hypertension, recurrent aortic stenosis, aortic aneurysms, and coronary artery disease. Reduced exercise capacity in cardio-pulmonary exercise test is related to hypertensive reaction and chronotropic incompetence.
