This single-centre propensity matched study aimed to compare the outcomes between patients undergoing transapical TAVI or surgical aortic valve replacement in patients who have previously undergone cardiac surgery. Patients who underwent procedures between 2005 and 2012 were included with 40 patients in each group following propensity matching. The majority of patients in both the redo TAVI and redo surgical AVR group had previously undergone CABG. Post-operative permanent neurological defect was more common in the redo surgical AVR group with a trend towards lower 30-day mortality in the redo TAVI group. At four years follow up there was no difference in overall survival between the groups but there was a statistically significant difference in major adverse events which was driven by the rate of permanent neurological deficit in the redo surgical AVR group. The incidence of mild/moderate paravalvular leak in the redo TAVI group was 33%.
