Intervencionismo coronario percutáneo en Navarra. Resultados de un centro de bajo volumen intervencionista

Abstract

Background. Percutaneous coronary intervention (PCI) is currently a basic therapeutic option in patients with coronary artery disease. To carry this out specialists must be trained and accredited. It is known that the number of procedures performed each year influences results. We suggest that some low volume centres may also get good results.Methods. Prospective analysis of clinical features and immediate results obtained in our centre following PCI performed between 2006 and 2012 and retrospective analysis of overall survival, outcome-free survival and restenosis in patients treated between 2006 and 2009. The clinical features, acute and long-term events (complications, survival and mortality) of our group were compared with other published studies.Results. In our centre the likelihood of complications in a PCI was 9% with an overall mortality of 2%. PCI mortality in stable coronary disease was 0.43% and in acute coronary syndrome 6.25%. Complications at the vascular access site was 1.44% and restenosis at nine months, in patients undergoing PCI for the first time, was 5.2%.Conclusions. Although a high interventionist volume has been shown to reduce the rate of complications and improve long-term evolution, some low volume interventional centres can obtain similar results to those of high volume interventional centres.Key words.
