    [ES] Este trabajo analiza la historicidad de la narración épica conocida como Leyenda de los Infantes de Lara. Frente a la visión tradicional, que atribuía a este relato una gran fidelidad a los hechos históricos, se sugiere una imagen más compleja, que mezcla elementos nuevos y más antiguos: 1) Un posible núcleo histórico consistente en la historia de Ruy Velázquez; 2) Una parte más compacta formada por la trama de la venganza de sangre, que enlaza la traición con la venganza de Mudarra. Frente a la idea tradicional de que la venganza es una completa ficción elaborada mucho tiempo después, se sugiere que traición y venganza constituyen una unidad lógica, aunque no se relacione con hechos históricos concretos. Es muy probable que el núcleo central de la leyenda, tal y como nos ha llegado, sea más bien un conjunto amplio de temas y motivos entretejidos con hechos históricos más o menos desfigurados. Finalmente, todas estas piezas cobran sentido en su contexto geográfico: la leyenda parece estar reflejando un conflicto entre Lara y Salas, leído desde el punto de vista de Salas, con una clara hostilidad hacia Lara.Peer reviewe

    Abstract Background Contemporary transcatheter and minimally invasive approaches allow for improved cosmesis and eliminate sternotomy; however, access to a ‘Heart Team’ approach to minimally invasive atrial septal defect (ASD) repair remains limited in Canada. Methods Retrospective chart review of all minimally invasive atrial septal defect repairs performed between 2009 and 2017 at a quaternary cardiac care centre were included. We compared residual shunt, functional status, periprocedural complications, and hospital lengths-of-stay between patients undergoing transcatheter and minimally invasive endoscopic ASD repair. Results Between 2009 and 2017, 61 consecutive patients underwent ASD repair at a single centre: 28 patients underwent transcatheter closure (64.3% female; median age 57, interquartile range 43–70.5) and 33 patients underwent minimally invasive endoscopic repair (72.7% female; median age 37, interquartile range 24–50). Patient demographics were similar between the two groups with the exception of transcatheter patients having smaller defect size (1.65 cm versus 2.35 cm, p = 0.002). Procedural success was 93% (26/28) and 100% (33/33) for transcatheter and minimally invasive groups (p = 0.21), respectively. Periprocedural complications were similarly low between the two groups with the exception of longer hospital length-of-stay in the surgical patients (5 days vs 1 day, p < 0.0001). Over a follow-up period (transcatheter: 0.5–56.5 months, surgical: 0.25–89 months), there was no difference in residual shunt (14.3% versus 6.1%, p = 0.4) or NYHA I Functional Class (88.5% versus 96.9%, p = 0.21). Conclusion Transcatheter and minimally invasive approaches to ASD repair are safe and feasible in selected patients using a ‘Heart Team’ approach and represent attractive alternatives to median sternotomy
