OBJECTIVE: To analyse the anatomo-clinical characteristics of the coarctation of the aorta at different ages of presentation as well as the findings and results of its surgical correction at different periods. PATIENTS AND METHODS: We retrospectively studied the clinical and angiographic data, as well as the intraoperative findings and surgical outcomes of 82 consecutive patients (54 M and 28 F) with coarctation of the aorta. Mean age was 16.2 +/- 13.7 years (1 month to 63 years). The patients were divided into three groups according to age: Group A (n = 10) under 1 year; Group B (n = 30) from 1 to 12 years and Group C (n = 42) over 12 years. RESULTS: A preductal form was found in 20.7% cases (50.0%, 30.0% and 7.1% of groups A, B, and C respectively; p = 0.003). An associated left-to-right shunt was present in 19.5% (40.0%, 16.7% and 16.7% of groups A, B and C respectively; p = NS). The first manifestation of the disease was different in groups A, B and C. Among group A patients, congestive heart failure was the most frequent presentation (70.0%). In group B, the most frequent presentation (30%) was as an incidental finding in an asymptomatic patient. Finally, systemic hypertension or its complications predominated among group C patients (38.0%). Left ventricular hypertrophy on ECG was present in 0.0%, 30.0% and 54.7% of patients in groups A, B and C (p = 0.003) respectively. Postoperative complications including death, hypertensive crisis and re-coarctation were observed in 90.0%, 33.3% and 21.4% in groups A, B and C (p = 0.01) respectively. CONCLUSIONS: Among patients with coarctation of the aorta, the age of clinical presentation allows us to define groups of patients with different anatomical characteristics, clinical course and postoperative outcome.
