Alternative treatment option for high risk surgical candidates after previous cardiac surgery: The Scottish National TAVI Programme experience

Results Mean logistic Euroscore was 29.6 for redo-TAVI compared to 18.6 for redo-SAVR (p < 0.05). Type of previous cardiac surgery performed in each redo group is summarised in Table 1. TAVI access was transfemoral (65.5%), transapical (6.7%), or trans-aortic (27.8%). Despite a higher incidence of MACE (major adverse cardiac events) in SAVR patients, results indicated no significant differences between two groups in terms of all-cause and cardiovascular related mortality, stroke, myocardial infarction. In details, hospital mortality was higher in SAVR group (5.1%) compared to TAVI group (2.2%), although it did not reach statistical significance. There was a higher incidence of CVA in the SAVR versus TAVI group (6.8% vs. 2.2%; p = 0.385). Patients were found to require permanent pacemaker insertion more often after TAVI (10% vs 3.4%; p = 0.2). Finally, average length of post-operative hospital stay was significantly shorter in TAVI than SAVR group (5.4 vs 10.4 days ; p < 0.00001).
