CERVANTES SALAZAR, Jorge Luis et al. Sugical treatment of aortic coarctation: Long-term results at National Institute of Cardiology of Mexico. Arch. Cardiol. Méx. [online]. 2006, vol.76, n.1, pp.63-68. ISSN 1665-1731.

Objectives: Evaluate long term evolution of patients submitted to surgery for coarctation of the aorta. Compare event free survival in younger vs older patients at the time of surgical correction. Methods: We reviewed the clinical records of patients operated for coarctation of the aorta from January 1 1980 to December 31 1994. The mean follow-up ranged from 9 to 23 years (mean 10.9 y). Final events registered were recoarctation, death, systemic hypertension, endocarditis, stroke, aneurisms. Results: Two hundred and sixteen patients were found with mean age 13 ± 12 y male gender was most frequent (61%). Recoarctation was found in 13 patients (6.02%), persistent hypertension in 14.1%. Event free survival at 10 years was 86.2%. In patients less than 10 y was 89% vs 80.2% in older patients. Hypertension free survival in patients less than 10 y was 98.3% vs 80.1% in older patients (p < 0.001). Conclusions: Our data confirms that surgical treatment for coarctation of the aorta is associated with low morbidity and mortality at long term with reduced rate of recoarctation (7%). Early correction (< 10 y) is associated with a better long term survival. Hypertension and use of pharmacologic treatment are reduced after surgery and persist in the long term evolution.
