Abstract

MARQUEZ-GONZALEZ, Horacio et al. Late complications of aortic coarctation treatment: a mexican cohort study with more than 10-year follow-up. Rev. Mex. Cardiol [online]. 2015, vol.26, n.4, pp.169-173. ISSN 0188-2198.

Aortic coarctation's (CoA) prevalence is 0.2 in every 1000 live births. Therapeutic options include surgery and, for the last 20 years, interventional cardiology. Objective: To determine the complications of CoA and examine their association with the type of treatment recieved. Methods: Patients that underwent CoA treatment and had follow-up in our center were included. They were included according to treatment in 3 groups: balloon aortoplasty (group 1), stent aortoplasty (group 2) and open surgery (group 3). Patients who suffered from interrupted aortic arch and those who received treatment in other hospitals or presented complications detected in other hospitals were excluded. Data analysis: Descriptive statistics with central mean tendency and dispersion according to distribution, inferential statistics, X-square, ANOVA/Kruskal-Wallis and Kaplan Meier analysis of survival. Results: n =166, age = 18 (range 13-25), 118 male (71%), 48 in group 1, 57 in group 2 and 61 in group 3. The mean follow-up was 15 years. From the analyzed complications, those with statistical significance were: persistent systemic arterial hypertension (group 1, 15%; group 2, 34%; group 3, 41%, p < 0.001) and re-intervention (group 1, 58%; group 2, 11%; group 3, 36%), p = 0.03. Conclusions: The balloon aortoplasty presents greater percentage of reoperation; and aortoplasty stent has fewer complications, but these are manifested in less time
