  1. Patient characteristics after removal of patients/records which met an exclusion criterion. A total of 243 records from 124 patients (38 MVR, 57 AVR, 29 TAVI) was analyzed. We are reporting on 38 patients with MVR, 17 of whom appeared in [12]; on 57 patients with AVR, 26 and 34 of whom appeared in [12] and [13], respectively; and on 29 patients with TAVI, 24 of whom appeared in [13]. p values for categories ‘age’ and ‘time of surgery’ resulted from the Kruskal-Wallis test; for the remaining categories, the cross-table χ2 test of independence was applied. Note that the characteristics within the groups change accordingly the patients which could be used at a given time instant. aIn 15 patients, transfemoral access was performed and in 14 patients, through the left ventricular apex (overall 29 patients). At time instants preOP, 1d postOP, and 7d postOP, 12, 8, and 8 transfemoral patients and 12, 8, and 6 patients were included into the analysis. bThe information was available for 29/22/19 (MVR), 42/33/28 (AVR), and 18/14/14 (TAVI) patients. sd, standard deviation; n.s., not significant.
