Caracterización de los efectos tisulares en los segmentos adyacentes a los stents liberadores de paclitaxel según el análisis de datos de radiofrecuencia procedentes de ecocardiografía intravascular seriada: estudio BETAX (BEside TAXus)

Serial expansive vascular remodeling was observed at proximal and distal stent edges. Remodeling occurred in response to tissue growth, which was mainly due to increased fibrofatty tissue.
