METHODS: We performed an observational retrospective study of 51 paediatric patients subjected to percutaneous closure of an ASD in the \"Complejo Hospitalario Universitario de La Coruña\", between 1999 and 2008.
RESULTS: A total of 51 procedures were performed, with an average of follow-up of 57.2 months. 75.7% of the families knew about the prophylaxis of endocarditis. This percentage was higher if less time had passed since the intervention and was also higher depending on the educational level of the parents. A total of 50% never stopped carrying out the endocarditis prophylaxis. In this case, a relationship was also observed, with the educational level of the parents and with the time passed since the intervention (P=0.004). The majority (73%) of the patients never had to carry out endocarditis prophylaxis.
CONCLUSIONS: The latest guidelines on antibiotic prophylaxis of endocarditis are increasingly restrictive in their indications in order to promote a more rational use of antibiotics. More studies are needed on the indications of antibiotic prophylaxis in endocarditis in patients with an intracardiac device, in order to establish concrete or evidence-based guidelines. Meanwhile, it is our responsibility to avoid the indiscriminate application of antibiotics, and involve the families and other health professionals.
